This is Apollo/Saturn Launch Control T minus 1 hour 30 minutes 55 seconds and counting. All elements are GO with the countdown at this time, the countdown aimed at landing 2 astronauts on the Moon. At this time the spacecraft Test Conductor Skip Chauvin going through some checks with astronaut Mike Collins aboard the spacecraft. We're winding up this important emergency detection system test that Neil Armstrong has been participating in. Meanwhile, at the 320 foot level the closeout crew now placing the boost protective cover over the hatch now that we have completed the cabin purge and have the proper cabin environment inside the cabin. We have also performed leak checks to assure ourselves that the cabin atmosphere is valid. This boost protective cover is used during the early phases of a powered flight and it is jettisoned with the escape tower shortly after second stage ignition. Here in the firing room the launch vehicle test team's still keeping a close eye on the status of the propellants aboard the Saturn V launch vehicle. We're back to 100 percent supply with the liquid hydrogen fuel in the third stage. This problem with the leaking valve is no problem at this time. We've actually bypassed the valve that we are maintaining our hydrogen supply aboard the vehicle. All aspects GO, the weather is very satisfactory this morning, a thin cloud cover about 15,000 feet, temperature at launch time exected to be about 85 degrees. At T minus I hour, 29 minutes, 30 seconds and counting, this is Kennedy Launch Control.

At this point in the countdown Spacecraft Commander Neil Armstrong once again appears to be the busiest worker in the spacecraft as he is performing a series of alignment checks associated with the guidance system in the spacecraft. He is working these checks with the spacecraft test conductor as the test conductor reads out the various procedures and Armstrong responds to them. The astronauts aboard the spacecraft also were informed by the spacecraft conductor a short while ago that the launch vehicle is GO at this time. The hydrogen problem that we did encounter earlier has been solved. That is real good news said Armstrong and then he went back to work shortly thereafter. We are now coming up on the 1 hour, 20 minute mark in the countdown. This is Kennedy Launch Control.

This is Apollo Saturn Launch Control. T minus one hour, 11 minutes, 55 seconds and counting. The countdown for Apollo 11 still going very satisfactorily at this time. In most cases we're a matter of 5 or 10 minutes ahead of the countdown procedures. The crew in the white room at the 10 and 20 foot level who have been aiding the astronauts up to this time are just in the process of finishing up their work. They've been advised by the spacecraft test conductor that they'll probably be able to move out in about 3 minutes or so. Once this is accomplished, once the close-out crew does depart, we'll be ready to move that swing-arm back - swing-arm 9. It will be moved 12 degrees away from the spacecraft hatch which is about 5 feet away from the hatch. Once this is accomplished, we will arm the pyrotechnic systems in the spacecraft so in the event of a possible catastrophic condition below them, the launch vehicle, while still on the pad, the astronauts could fire that escape rocket and separate from the rocket in difficulty. The close-out crew are about to depart at this time. That swing-arm remains about 12 degrees away from the spacecraft hatch as mentioned - 5 feet or so until the 5-minute mark in the count when it's fully retracted to it's fall-back position. The obvious reason here is in the event we do have to get the astronauts out in a hurry, the swing-arm is in a stand-by position and could be moved rapidly back to the hatch - to the hatch level so the astronauts could depart in the event of an emergency. We're coming up on T minus 1 hour, 10 minutes, and 20 seconds. This is Kennedy Launch Control.

Astronaut Neil Armstrong has just completed a series of checks on that big service propulsion system engine that sits below him in the stack. We want to assure ourselves before liftoff that that engine can respond to commands from inside the spacecraft. As Neil Armstrong moved his rotational hand controller we assured ourselves that the engine did respond by swiveling or gimballing. This is - course is important for maneuvers in space. The countdown is still proceeding very satisfactorily other than two minor problems essentially picked up the count at 11 pm eastern daylight time last night, all has gone well. As we approach the one hour mark now, in the count of series of radio frequency and telemetry checks will be in progress with the launch vehicle.

We alert the astronauts because there is a little jolt when this arm is moved away. It will remain in that position some 5 feet away from the spacecraft until the 5 minute mark in the count when it's completely pulled away to its retracted position. It's coming up now in 5 seconds, the swing arm will come back. Mark. The swing arm now coming back from the spacecraft.

The hard work on the spacecraft at this point in the countdown - Astronaut Buzz Aldrin in the middle seat. He's been working with the spacecraft test conductor on setting up proper switch settings in preparation for pressurizing the reaction control system. These are these big thrusters on the side of the service module. There's actually 16 of them in 4 quadrants around the service module. They are used for maneuvers in space. We pressurized that system before liftoff. That particular operation will be coming up in some 5 minutes or so. In preparation for it, Buzz Aldrin who has most of the switches in front of him has been preparing for that particular event. The launch vehicle people keeping an eye on the status of the various propellants aboard the Saturn V launch vehicle. Just at liftoff, we will have the vehicle weighing close to 6 and a half million pounds on the launch pad. There's more that a million gallons of propellants aboard the 3 stages of Saturn V. The report here in the control center are the propellants are stable. They did look a little while ago at the RP 1, the high-grade kerosend fuel that's used in the first stage of the Saturn V to make sure it was at it's top level.

As far as the launch vehicle people are concerned, it's a - some final checks of the destruct system aboard the three stages of the Saturn-5 launch vehicle. In the event during powered flight that the vehicle strayed rather violently off course, the main safety officer could take action to destroy the vehicle which obviously would occur after the astronauts were separated by their escape tower from the faulty vehicle. We'll make a check of the destruct system to assure that if the signal is required to get through that, in fact, it will. This is what is coming up here in the control center at this time.

The countdown still proceeding very satisfactorily at this time. We've got by an important test with the launch vehicle checking out the various batteries in the 3 stages and instrument unit of the Saturn V. We remain on external power through most of the count to preserve those batteries which must be used during the powered flight. We've just taken a look at them by going internal and then switching back to external again. The batteries all look good. The next time we go internal will be at the 50 second mark with those batteries and they will remain, of course, on internal power during the flight. The lunar module, which has been rather inactive during these latter phases of the count also is going on internal power at this time on the 2 batteries on the ascent stage and the 4 batteries on the descent stage. For the next 20 minutes we will take a look at some systems in the lunar module and then power down at about the 10 minute mark in the count, power down the telemetry to preserve the power of the LM. The lunar module on Apollo 11, of course, when it separates from the command module in lunar orbit, will have the call sign Eagle.

Close to 3/4 of a million gallons of propellants were loaded during these 5 hours. Following that the astronauts, the prime crew, were awakened at 4:15 a.m. Eastern Daylight as planned in their countdown, and proceeded to have their physical examination in which they were declared flight ready. They sat down for the normal astronaut meal on launch day as far as breakfast is concerned, orange Juice, steaks, scrambled eggs, toast and coffee. The 3 pilots were joined by 2 of their coleagues at breakfast, Director of Flight Crew Operations Deke Slayton and the backup command module pilot Bill Anders who has been named the Executive Secretary of the National Aeronautics and Space Council. The astronauts departed from their crew quarters. After checking out their suits they departed from the crew quarters at 6:27 a.m. and some 27 minutes later and 8 miles away from the crew quarters at the Kennedy Space Center a top the launch pad at complex 39, 6:54 a.m. the commander, astronaut Neil Armstrong, was the first aboard the spacecraft. He was followed about 5 minutes later by Mike Collins and finally Buzz Aldrin, the man who is sitting in the middle seat during liftoff, was the third astronaut to come aboard. Two minor problems have been encountered during the count. Early in the count a malfunction light came on here in the control center indicating that we might have a communication problem at the launch pad. Nothing to do with the spacecraft, but it indicated we possibly might not be able to talk to some key technicians we had at the pad. The problem turned out to be very minor, a simple adjustment of some equipment beneath the pad remedied the problem. There was no, in fact, no equipment problem involved. The second problem, we did encounter a leaky valve in part of the equipment that is used to replenish the hydrogen fuel supply on the third stage of the Saturn V launch vehicle. A team of technicians were sent up to the launch pad at about the time the astronauts were traveling to the pad. They tightened some bolts and we were able to bypass this valve and to proceed with our countdown. The weather is certainly GO. It's a beautiful morning for a launch to the Moon. We expect a temperature of about 85 degrees in the Kennedy Space Center area. The wind is about 10 knots from the southeast, and the weather condition in the round-the-world track, according to reports to the Manned Space Flight Meterology group indicate all weather conditions are acceptable for launch.

The astronauts aboard the spacecraft have had a little chance to rest over the last few minutes or so. At least they have not been busy with procedures with the spacecraft test conductor. In the meantime we have been performing final checks on the tracking beacons and the instrument unit which is used as a guidiance system during the powered phase of flight. Once we get down to the 3-minute and 10-second mark in the countdown, we'll go on an automatic sequence. As far as the launch vehicle is concerned all aspects from there on down will be automatic, run by the ground master computer here in the firing room. This will lead up to the 8.9-minute mark in the countdown when the ignition sequence will begin in those five engines of the first stage, the S-IC stage of Saturn V. At the 2-second mark we'll get information and a signal that all engines are running and at the zero mark in the countdown once we get the commit signal, the signal that says that the thrust is proper and acceptable, we then will get a commit and liftoff as the hold-on arms release the vehicle.

CAPCOM
Roger. Could you give us comments on how the transposition and docking was? Over.

SC
I thought it went pretty well, Houston. Although I expect I used more gas than I've been using in the simulator. The turn around maneuver, I went pitch accel command and started to pitch up, and then when I started to pitch up, and then when I put manual attitude pitch back to rate command for some reason it - it stopped its pitch rate, and I had to go back to accel command and hit what I thought was an extra proceed on the DSKY. And during the course of that we drifted slightly further away from the S-IV B than I expected. I expected to be out about 66 feet. My guess would be I was around 100 or so, and therefore I expect I used a bit more coming back in. Except for using a little more gas, and I've used a few numbers on that everything went nominally.

Designed to put the third stage of the launch vehicle into a trajectory that will take it behind the trailing edge of the moon and then into a solar orbit. The crew did not witness this maneuver. The command was not in the proper attitude where they could see the S-IVB at the time. We've advised the crew that we do not believe that we'll do the first midcourse correction. That we'll wait for midcourse correction 2 tomorrow and expect a DELTA V to be performed in that maneuver of about 21.3 feet per second.

Lunar Module Pilot, Buzz Aldrin apparently got out of his pressure suit about 1 hour earlier or about 7 hours ground elapsed time. The spacecraft is currently 44,529 nautical miles from earth and the velocity has dropped now to 8983 feet per second. We do have, rather poor lock with the spacecraft antenna at this time accounting for the noise on the air to ground circuit. We'll take down the circuit until we reestablish better lock and we'll record any conversations that occur in the interim. At 9 hours, 14 minutes this is Apollo Control Houston.

Hello, Apollo 11. Houston. We've been noting some funnies on the O2 flow indicator. For instance, we kind of got a suspicion that the transducer - we expected to see an O2 flow pegged high with the waste stowage vent to VENT. It was not. We also noted some funny indications when you closed the waste stowage vent valve. We're going to take a look at this through the night, and we'll be with you in the morning with an assessment of the problem. Also, we'd like to ask specifically, when you place the waste stowage vent valve to vent does the detent - correction - does the arrow line up with the detent? Over.

flow, as we would have expected at this point. This would indicate that the enrichment of the cabin atmosphere, which was 60 percent oxygen, 40 percent nitrogen at launch and which is normally enriched with pure oxygen during the course of the/flight, is not enriching as rapidly as we would expect. This could be a transducer problem - one of the devices that measuzes the O2 flow rate - or possibly a partial obstruction of one of the vents. The problem is not thought to be significant at this point, and we'll be monitoring the O2 flow during the night.

It's working good so far, Charlie. We've got one installed on the water gun and the other one installed on the spigot down in the LEV, and we - like to mention one problem with them is that they leak at the junction between the food bag and the water filter, however with that extension they seem to be working pretty good.

At about 11 hours, 20 minutes we said good-night to them from Mission Control and they're beginning their sleep period about 2 hours early. The additional time available for sleep was made available by deleting the mid-course correction. The first opportunity which occurred at 11 hours, 45 minutes. That mid-course correction has been moved to mid-course correction 2 to the opportunity of mid-course correction 2 of which would occur tomorrow. The last conversation we had with the crew, we received a status report and a report that they had taken no medication and were "fit as a fiddle". We also got a report from Mike Collins on the gas separation unit which is being flown on this flight. This consists of 2 stainless steel cylinders about 5 inches long and about an inch to an inch and half in diameter. The cylinders are attached to the water gun or to the water spigot on the food preparation panel and remove the gas from the water that flows through the filter. The filter actually has 2 filters inside. One which attracts water and one which repels it, in the process removing the gas. Mike Collins reported that the filters seem to be working quite well. That the water was coming out almost free of bubbles. He did report that they had a minor problem with a leak at the junction between the food bag and the filter. Mission Control advised that we would give that some thought and try to come up with some solution to it when they wake up tomorrow.

We have not been able to visually pick up the Hawaiian Island chain but we can clearly see the western coast of North America, the United States, the San Joaquin Valley. The High Sierra's, Baja, California and Mexico down as far as Acapulco and the Yucatan Penninsula and you can see on through Central America to the northern coast of South America, Venezeula and Columbia.

That concludes the unscheduled television transmission. That transmission came in about 2 hours ago at a ground elapsed time of 10:32:40 beginning, lasted about 16 and a half minutes. At the beginning of the transmission Apollo 11 was about 50,980 nautical miles from earth and at the conclusion about 52,248 nautical miles. At the present time, the crew is in a scheduled rest period. They did indicate before going into the rest period, when we last heard from them, that they would probably use part of the time to get a bite to eat and then get some sleep. At this time Apollo 11 is 59,908 nautical miles from earth, traveling at a speed of 7,569 feet per second. At 12 hours 31 minutes, this is Mission Control, Houston.

This is Apollo Control at 12 hours 47 minutes. We've just put in a call to the crew. Flight Director, Gene Kranz, verified with the surgeon that they had not gone to sleep at this point and Capsule Communicator, Charlie Duke, has put in the call. We'll pick up the tape of the converstion and then stand by for any following live communication with the crew.

CAPCOM
Roger. When you stopped, or correction, when you terminated the noun 65, it appears to us, you get a verb 46 which collapsed the deadband back to 0.5. We're okay as long as you do not turn on any auto RCS select switches. Over.

SC
Okay. I've got that one, Jack. We're ready to ... Roger.

CAPCOM
Roger, verb 34 would have been a better procedure.

SC
Yeah.

PAO
This is Apollo Control. We don't anticipate a great deal of further conversation wit the crew. We expect they will attempt to get some sleep shortly. The converstion that just ended, we advised that through one of the computer programs, the deadband for that area of excursions which the guidance system will allow befor firing the RCS thrusters to correct it. It had been narrowed from 30 degrees to 1/2 a degree. What this would mean, if the RCS jets were enabled, is that unless the crew reselected the 30 degree deadband, the jets would be firing more frequently to keep the spacecraft within the narrower limits. Since the spacecraft is very stable at this point, very few wobbling motions, it was felt that the narrower deadband was acceptable; the jets are not enabled, and the crew would not be disturbed by firing of the Reaction Control System jets even if the spacecraft moved out of the 1/2-degree deadband. In the event of any large excursions, which we would not expect, based on the passive thermal control mode, used in Apollo 10. It would be possible to awaken the crew from the ground and have the situation corrected. We would not expect, however, for the spacecraft attitude to change significantly during the night, and we do intend to continue in the passive thermal control mode as it is presently set up. At this time Apollo 11 is 61,509 nautical miles from earth, traveling at a speed of 7,449 feet per second, which would translate to about 5,000 miles an hour. At 12 hours 54 minutes, this is Apollo Control, Houston.

Agnew, ranking government official at the Apollo 11 blastoff Wednesday, apparently was speaking for himself and not necessarily for the Nixon administration when he said, "We should, in my judgement, put a man on Mars by the end of this Century". Laredo, Texas, AP: Immigration officials in Nuevo Laredo announced Wednesday that hippies will be refused tourists cards to enter Mexico unless they take a bath and get haircuts. Nuberto Cazaras, Chief of Mexican Immigration in Nuevo Laredo, said authorities in Mexico City, Alcapulco, and other popular tourist spots have registered complaints about the hippies. United Press International: Initial reaction to President Nixon's granting of a holiday Monday to federal employees so they can observe a national day of participation in the Apollo 11 moon landing mission mostly was one of surprise. Rodney Bidner, Associated Press: London AP: Europe is moon struck by the Apollo 11 mission.

Okay. For today, we'd like you on P-23 to make a trunnion bias determination prior to P-23 sitings as called out in procedures and also one afterward. Our intent here is to check out the possibility that some sort of thermal effect may be giving you errors in the angular readout in the section. The bias that you get beforehand should be incorporated, that is proceed on NOUN 87 after you get 2 consecutive measurements equal it will then point 003 degrees, and of course move the trunnion off a couple of degrees between the measurements. The Earth should be a lot smaller in your field of view today, I'm sure you're a lot more qualified to tell us about that than we are, but to insure that you're getting a good angle measurement between the star and the Earth horizon, the section M-line, which is the line that runs through the 2 hash marks and is perpendicular to the R-line, should be parallel to the Earth horizon at the substellar point. And then the actual super imposition of the star on the horizon can be made at any point in the field of view of the section above, below, or on the M-line. We recommend the marks be made as rapidly as possible after the AUTO maneuver.

Houston, Apollo 11.

CAPCOM
Go ahead, 11.

SC
Okay, we're stopping PTC now and maneuvering to our P52 and optics cal attitude. And we're going to the P23. What I was trying to tell you yesterday was about that. The M line is not anywhere parallel to the horizon at the roll, pitch and yaw which you give me to go to for the substellar point, and I was trying to maneuver off to get it parallel to the horizon when you all said that was unnecessary.

CAPCOM
Roger, 11. I guess in keeping the cups of coffee strong, why you get that one.

SC
Well - okay - well, this morning, let's just see how close it comes to being parallel to the M line. Before we started marking for the first time it appeared that the computation of - of those three angles was somewhat off, and that I was wasting a lot of gas by going to those three angles and then having to make a large attitude changes after that to get the M line parallel, and in some cases it appeared to be just an accepted attitude required, and you all said that it wasn't needed. So I was marking in some cases with the M line not parallel. I thought perhaps you had some processer for computing that offset and making sense out of that data, but as far as I know we gotta have the M line parallel.

CAPCOM
Roger, 11. We don't have that capability. We do require that the M line be parallel to the horizon in order to get a good mark. We feel that possibly the - the state vector information that you were using for your maneuver basis yesterday may have needed to be updated a little, and if you'll stand by a second we'll give you an evaluation of what we feel you'll get today by the auto maneuver.

SC
Okay.

SC
Houston, Apollo 11. Over.

CAPCOM
Go ahead, 11.

CAPCOM
Yes, please, stand by a second.

SC
Okay.

CAPCOM
11, this is Houston. On our TM here we're only seeing values in 2 registars. Can you read us out the contents of registar 3, please.

SC
Registar 3 minus 3 balls 2 4.

CAPCOM
Roger, minus 3 balls, 2 4, and you can go ahead and proceed.

SC
Okay, proceeding at this time.

CAPCOM
11, Houston, after you've completed P52, we'd like the up flight you on state vector, so we can start out clean on this P23, over.

SC
Okay. Houston, are you observing the higher O2 flow on fuel cell 3? Houston, Apollo 11, it triggers the master alarm 3 times now - there it goes number 4. It goes up to about 1.4 and then oscilates back down to about 1.1 , over.

CAPCOM
Roger, we saw them 1.3 now, on TM - stand by a second.

SC
And we're through now for state vector.

CAPCOM
Roger, give us accept, please.

SC
Roger.

CAPCOM
11, Houston. On our O2 flow fuel cell 3, apparently it was flowing a little higher than the other two during purge, but the flow rate is acceptable, over.

SC
Roger, it seems to be flowing a little bit more, and actually putting out more current than the other two, also, over.

APOLLO 11 MISSION COMMENTARY    7-17-69     CDT 8:56  -  GET 24:24  -  TAPE 90/1

SC
- 37. Is that all right for the optics calibration to save some gas, or do you want to go over to Star 40?

CAPCOM
Star 37 will be fine for the optics calibration and we haven't noticed a VERB 66 yet after our state vector uplink. Over.

SC
Okay.

CAPCOM
When you move into P-23, we recommend that you use the CMC computer angles for your auto maneuver. See how that works out. If it doesn't bring you up with the M-line parallel to the horizon to the substellar point, we will see if we can get you some ground computed angles. I guess the big thing here is to make sure that the M-line is parallel to substellar points so we can get a good angular measurement. Over.

SC
Yes, I believe.

CAPCOM
Roger. Roger.

PAO
Star 37 is Nunki. Apollo 11 is now in program 52 which is realignment of the platform prior to beginning the cislunar navigation operation.

SC
This is Apollo 11. Marking on this star, I get a 987 twice in a row of five balls so that's sufficient for a count.

CAPCOM
That's certainly very sufficient.

SC
Okay.

SC
Now I want to go to P00 and I am going to take your three angles and do a verify of 49 maneuver to your substellar point. Okay?

CAPCOM
Okay. We recommend that for the first star, if we gave you a new state vector, we'd like to try the CMC computed angles for your auto maneuver.

SC
Okay.

CAPCOM
And have you hit PROCEED on this display to enter the zero?

SC
Not yet.

SC
No, we haven't changed any cannisters this morning.

Okay. Then you can plan on accomplishing that after P-23 is over and you've got the LEB clear.

Roger, we copy. And that is for Star Zero 1?

SC
Star Zero 1 right near the horizon. Code 110.

CAPCOM
Roger.

SC
Houston, Apollo 11. On this star the auto maneuver works just fine and I am right at the substellar point. Everything looks beautiful except there is no star in sight. It is just not visible.

CAPCOM
Roger. Is this for Star 01?

SC
That's correct.

CAPCOM
You are not getting any reflections or anything like that that would obscure your vision, are you?

SC
Well, of course, the earth is pretty bright and the black sky, instead of being black, has sort of a rosy glow to it and the star, unless it is a very bright one, is probably lost somewhere in that glow, but it is just not visible. I maneuvered the reticle considerably above the horizon to make sure that the star is not lost in the brightness below the horizon. However, even when I get the reticle considerably above the horison so the star should be seen against the black background, it still is not visible.

CAPCOM
Roger, we copy. Stand by a minute, please.

CAPCOM
11, this is Houston. Can you read us the shaft and trunnion angle off the counters?

That's right. I - I haven't entered, I gave it back to the computer for a second.

In general, the color of the oceans is mostly uniform and it's, oh bright and darker blue except for that region that's about 1/8th of an earth's radius in diameter, and in this circular area the blue of the water turns a grayish color and I'm sure that's where the sun's rays are being reflected back on up toward us. Over.

CAPCOM
Roger, Buzz. We noticed the same thing, It's very similar to looking at a light shining on something like a billiard ball or bowling ball. You get this bright spot in the blue of the water and that turns it sort of a grayish color.

SC
Yes. Is there a Navy term for that?

CAPCOM
A lot of gray paint.

CAPCOM
11, Houston.

SC
Go ahead, Houston.

CAPCOM
Mike, are you satisfied with P23 now?

SC
Yes, I'm happy with the last updates we got, you know, in terms of what it did to our state vector. Still not altogether happy with the various procedures. If we could pick stars within the smaller range of trunnion angles so that you could allow P23 to pick its own maneuver and go to that substellar point and then have that star visible, that would seem to me to be the simplest and best way to do it,

CAPCOM
How about the horizon now? Is it pretty well defined where it's no longer hazy?

SC
Yes, we're far enough out now that the - I think the horizon definition variation is lost in the noise.

SC
Hey, Jim.

CAPCOM
Go ahead, Buzz.

SC
Looks like the best outstanding view is through the monocular is just steady it out and let it close when it's in front of your eye and then you kind of float up next to it so you're not touching it at all. It has a very slow drift and you get a better view that way.

CAPCOM
Sounds good.

CAPCOM
How does it feel to be airborne again, Buzz?

SC
Well, I'll tell you, I've been having a ball floating around inside here, back and forth up to one place and back to another. It's just like being outside except more comfortable.

SC
- the PTC. It cooled off somewhat with the windows buttoned up and we've seen suit temperatures of about - the high 40's and cabin temperatures in the low 60's. But this seems to be still a little bit on the warm side.

CAPCOM
I understand it got a little warm during the day and cooled down a little bit when you put the shades up, but you're still a little bit warm. Have you have any moisture condensation or anything like that on the wall?

SC
No, we haven't been able to detect any moisture anyplace in the spacecraft. It seems to be fine.

SC
One of the hydrogen filters - the one that we've got on the hot water - seems to keep flowing when you remove one of the food bags from it. Its flow rate is quite small right near the end of one out, and that contributes a little bit of moisture to the atmosphere.

SC
Yes, that hydrogen thing, it's, I'm not sure, but I think it's a back pressure problem. If the thing sees any back pressure at all, like when the bag is attached, well the flow rate will slowly decrease to where its almost zero, and you wait, and you wait, and you wait for that last ounce. You think you have it, and you remove the bag, and then you very rapidly thereafter see maybe a glob the size of a dime or a quarter come out and just hang there. That appears to be true even though the opening into the bag is not restricted.

CAPCOM
Understand.

SC
In general, I think they do quite a good job, especially on the guns when we're moving a lot of the hydrogen bubbles.

CAPCOM
Are the water temperatures good? Are you getting hot water?

SC
Yes, it seems reasonably warm.

SC
We made 3 cups of coffee today. The last one - you know when all the plumbing was warmed up, the hydrogen gun and everything, was warmest of the 3. I don't know who had that one - Neil, did you have that one? How was your coffee? You didn't drink it till later, did you? Anyway, it's pretty good. It's not piping hot, but it beats stone cold coffee.

CAPCOM
11, this is Houston. As a result of our venting through the waste management drain we concluded that your O2 flow rate sensor is in fact malfunctioning. I mentioned when you start this through the cyclic water accumulator dump that even though it was moving, probably indicating a higher flow rate, it didn't seem to be indicating a flow rate that is high enough, and based on that and the flow that we're getting right now we concluded that the transducer is malfunctioning. We'd like to continue the O2 flow for about another hour, shuting off at about 31 hours    GET to get the O2 concentration in the vehicle up in the vehicles where it will be acceptable for the LM checkout. Over.

Okay. Does it look to you like it just has a bias on it?

Okay. Well, for this TV program coming up in a couple of hours, you might give some thought to how you want us to stop PTC, if you do, for the best high gain angle and also it would be nice if you could stop us at such an attitude that we'd have the Earth out of one of our windows.

CAPCOM
Roger, 11. We're thinking about that.

SC
Okay.

CAPCOM
Hello, Apollo 11; Houston. We got some pipa biases and general drift updates for you if you give us to an accept. Over.

SC
Okay, Charlie. Stand by one.

CAPCOM
Roger, 11. The - Okay, thank you much. Our biggest drift on the gyros is 0.03 degrees per hour with only X-gyro. On the pipas, the wide pipa's the biggest and it's 0.006 feet per second so we just kinda tweak it up. The biggest we have is about one sigma on both gyros and accelerometers.

SC
Sounds good.

CAPCOM
The system really looks good to us.

SC
And here, Charlie.

CAPCOM
11, Houston. You can go back to block. We accept the load in.

SC
Okay. Roger.

This is Apollo Control at 31 hours, 22 minutes. We're scheduled to begin the change of shift briefing shortly. During the briefing we will record any conversations with the crew and play those back following the briefing. At 31 hours, 22 minutes, this is Apollo Control.

This is Apollo Control at 32 hours 21 minutes. During the Change of Shift Press Conference we had about 3 minutes of conversation with the crew. During that conversation, Buzz Aldrin reported on - what appeared to be a weather disturbance off Cuba and the Caribbean and we also had some descriptions from Aldrin on the view of Earth from the spacecraft's present position. We'll played that back for you now and then stand by for any further live conversation with the crew.

SC
You sure do get a perspective in this thing in Zero G? Right now Neil's got his feet on the forward hatch and he can with his arms reach - oh - five windows. He can reach down into - oh, the LEB where the overboard drain is. He can practically reach over in the cockpit.

CAPCOM
Sounds like plastic man to me.

SC
I'm hiding under the left hand couch trying to stay out of his way.

CAPCOM
Be a good idea, Mike.

SC
All right Houston, Apollo 11. Do you have a cloud over the Houston area right now?

CAPCOM
Roger. We just had really big thunderstorm here about a hour ago. Couple of storms around the area right now.

SC
Yeah, I see one fairly large and isolated one. There are couple of more off to the left but this one looks fairly good size. It could very well be the one that just passed over you. It looks like the Cape has been having a little bit of rain too.

CAPCOM
Roger. The one we had here came in from the west and is moving east or nearly so as far as I could tell.

SC
Have news, this sextant is fantastic. I can see Alaska right up - right up along the LM and I am running the cross hairs right now down the coast of California, west coast of Mexico, Yucatan Peninsula, up around the Gulf, Florida, Cuba, down Central America and I'm running into the South now.

CAPCOM
Roger. It sounds like a pretty fantastic view.

SC
The guys in the weather office out at Patrick wanted a report on the top but I guess all we can say is that we are above them.

CAPCOM
Rog. We'll pass it on OMEGO.

SC
Houston, do you see any predominant weather systems as far as funnel type? Any buildup of tropical storm type? Over.

CAPCOM
Not any large ones. There are a couple of smaller disturbances - there is one maybe 300 miles north of Cuba but it doesn't look like.

Roger, - I am not sure I caught all of that.

CAPCOM
Roger, 11, if you will break out your alternate and contingency check list for the CSM, we got an update to some of the erasable loads on page F2-20, over.

Okay, we will be getting that out and you can give us the attitude for the (garble)

CAPCOM
Roger 11. Your TV attitude will be roll 261, pitch 090, yaw 000. High gain angle pitch plus 28, yaw 271. That puts the left-hand window pointed at the Earth. We recommend exiting PTC with your updated procedure in the check list. Over.

SC
Roger. We copy roll 21 - 261, pitch 090, yaw 000, high gain pitch plus 28 Yaw 271. (garble) Over.

CAPCOM
That's affirmative.

SC
Charlie, I have a couple of questions on the PTC. It seems to me that the easiest way to stop it would be - we're essentially on course at 0 degrees yaw and close to up a 90 degree pitch. It is just a question of stopping at 260 roll roughly and how about for a procedure going manual attitude three to REG command and then seeing how our deadband has already collasped, I will turn on our Panel 8 RCS thrusters at which time it should stop at whatever attitude it binds itself in and if I will do all of that as it comes up on 261 degrees roll we should stop right there - in that position.

CAPCOM
Sounds pretty good. Stand by one

SC
In other words, it might save on gas

Hello Apollo 11, Houston, with a recommendation on the exiting PTCM, over.

SC
Go ahead.

CAPCOM
Roger, Mike. We'd like to see you go to excell command on the manual attitude switches. Then to turn on the auto RCS select switches, and then go right to manned. That will prevent us from firing jets uncoupled, over.

SC
Okay, fine and I would guess go right command and roll first and then followed by pitch and yaw.

CAPCOM
Okay, that sounds good if, and when you get to the roll attitude desired just go right command at that time and that'll stop us right on.

SC
Yea I agree Charlie, that sounds right.

CAPCOM
Rog.

PAO
This is Apollo Control at 32 hours 39 minutes. This is a relative quiet period in the flight plan. The crew will be getting the spacecraft set up for the passive thermal control termination, and the Television transmission. Capcom Charlie Duke has just put in a call. We'll pick that up.

CAPCOM
Playing with the P37 while ago and we collapsed the dead-band back down. The dap assumed that the dead band was centered around the new attitude that we happened to be at at that time. Since then we've drifted out a couple of degrees in both pitch and yaw from that attitude, such that if we did the proceedure as we call it up to you of going excell command, turning on all of the auto RCS select switches and the rate command it would attempt to fly back to the pitch and yaw attitude that it had when the dead band collapsed. We can prevent that by just immediately priod to going to right command on the manual attitude switches, if you cycle the spacecraft control switch to SCS, then back CMC, over.

SC
Sounds like a winner.

CAPCOM
Okay.

Oh yes Charlie, I can see (garbled) now, and I can see the coast line is clear and those clouds are just inland a few miles.

Looks like the south east part of the country is all socked in. California looks nice, the San Joaquin Valley shows up as a real dark spot with a lighter brown around the side of it. You can't tell that it's green, it looks just sort of dark gray or maybe even a real dark blue.

Negative, Charlie. I just - I don't have that resolution, but to give you some idea, I can, in the lower sextant scope, I can see, after knowing what I'm looking for, I can see Padre Island. I can just barely make out the fact that there's a thin slit of land and then there's a little dark zone which is the Laguna Madre between it and the mainland.

This is Apollo Control at 33 hours, 34 minutes. We've been advised that we are getting television transmission from Goldstone at the present time. This is an unscheduled TV transmission apparently of the crew checking out their onboard system.

PAO
We have lost lock on the high gain antenna at this time. Apollo 11 is presently 127,991 nautical miles from Earth, traveling at a speed of about 4400 feet per second. The regularly scheduled time for the television transmission is 6:47 p.m. Central Daylight Time, and we are anticipating that that transmission will occur as scheduled.

We're getting momentary lock-on. We seem to have a somewhat better picture now. Here's a call to the crew from Capcom Charlie Duke.

Hello, Apollo 11; Houston. Over.

Okay. Thank you, Charlie.

CAPCOM
And also, President Nixon has reported - declared a day of participation on Monday for all Federal employees to enable everybody to follow your activities on the surface. Many state and city governments and businesses throughout the country are also giving their employees the day off, so it looks like you're going to have a pretty large audience for this EVA.

This is Apollo Control at 33 hours, 41 minutes. We are going to be standing by here in Mission Control for the possibility that the crew would want to transmit that television pass early. The scheduled time for it was 6:47 Central Daylight time and about 15 minutes was scheduled. That would be at a ground elapsed time of 34 hours and we will have the system set up here in Mission Control to receive and release television should the crew decide to send us the transmission early.

PAO
This is Apollo Control at 33 hours, 45 minutes and we do have a correction to the time given for the beginning of that TV nominally. The flight time is beginning at 34 hours to 34 hours, 15 minutes ground elapsed time. The previous conversion of that, that we gave you for Central Daylight Time was in error, it should be 6:32 P.M. Central Daylight Time beginning, assuming we start as the flight plan nominally has a transmission listed at 34 hours ground elapsed time. At the present time, Apollo 11 is 128,431 nautical miles from earth and the velocity continuing to drop off slowly, now reads 4386 feet per second.

You're seeing Earth, as we see it, out our left-hand window, just a little more than a half earth. We're looking at the eastern Pacific Ocean, and the north half of the top half of the screen, we can see North America, Alaska, United States, Canada, Mexico, and Central America. South America becomes invisible just beyond the terminator or inside the shadow. We can see the earth's ... a definite blue cast. See white bands of major cloud formations across the earth and can see coastlines, picked out the western US, San Joaquin Valley, the Sierra mountain range, the peninsula of Baja, California, and we see some cloud formations over southeastern US. There's one definite mild storm southwest of Alaska. Looks like about 500 to 1,000 miles and another very minor storm showing the south end of the screen near the - Oh, a long ways off of the equator, probably 45 degrees at a more south latitude. Can pick out the browns in the land forms pretty well. Greens do not show up very well. Some greens showing along the northeastern - northwestern coast of the United States and northeastern coast of Canada.

Roger. It's a pretty good picture of clarity, here. We're having - Can you tell us It appears to us that there are two of the same cloud formations trending eastwest. One approximately along the equator, and one around 30 or so south latitude. Can you tell us exactly where those cross the land masses? Over.

SC
Yes. They cross just south of the lower part of Mexico, probably through Central America. That is the equatorial band which we assume to be the intertropical convergence zone. Another band, which stands about 30 south correctly seems to appear to join equator

at the far left, or just beyond the horizon on the left edge of earth, or at least it looks like it's going to China. We don't have an explanation for that banding.

CAPCOM
Roger, Neil. Thank you.

SC
It also appears that just to the left of the terminator, up in the northern hemisphere, there's a cloud band trending a gap in the cloud, trending northwest southeast. It appears to us that that comes in about over the northern United States, or perhaps the Central United States. Is that about correct? Over.

I can see on the monitor the thing you were talking about but right now I can't get my eye to the window to pick out just where it crosses the shoreline.

SC
We can't observe much green from the spacecraft.

CAPCOM
Roger. On this monitor, the land masses appear to be just a darker grayish color rather than a brown.

SC
Well, it's true that we do not have the depths of color at this range that we enjoyed at 50,000 miles out. However, the oceans still are a definite blue and the continents are generally brownish in cast, although it is true that they're tending more toward gray now than they were at the closer range.

SC
Cue cards have a no. We have no intention of competing with the professionals. Believe me. We are very comfortable up here, though. We do have a happy home. There's plenty of room for the three of us and I think we're all willing to find our favorite little corner to sit in. 0 g's very comfortable but after a while, you get to the point where you sort of get tired of rattling around and banging off the ceiling and the floor and the side, so you tend to find a little corner somewhere and put your knees up, or something like that to wedge yourself in, and that's seems more at home.

CAPCOM
Roger, looks like Neil is coming in 5 by, there, 11. Mike, see you in the background. The definition is really outstanding. The colors are good. It's a real good picture we're getting here of Commander Armstrong. We - Buzz, when you take the camera over towards the window where the sun's shafting through it, it tends to black it out, though.

Now right behind my window of course we have the sun and the sun is illuminating the star charts that we see. This line represents the ecliptic plane and these line vertical lines represent our reference system that the spacecraft is using at this time.

We really have them, Charlie. We've got all kinds of good stuff. We've got coffee up here in the upper left and the breakfast items and bacon in little small bits, beverages like fruit drink and over in the centerpart we have, oh all kinds of things. Let me pull one out here and see what it is.

CAPCOM
Rog.

SC
Would you believe you're looking at chicken stew here. All you have to do is 3 ounces of hot water for 5 or 10 minutes. Now we get our hot water out of a little spigot here with the filter on it that filters any gasses that may be in the drinking water out, and we just stick the end of this little tube in the end of the spigot and pull the trigger three times for 3 ounces of hot water and then mush it up and slice the end off it and there you go. Beautiful chicken stew.

This is Apollo Control at 34 hours, 46 minutes. Apollo 11 is presently 131,000 nautical miles from Earth, traveling at a speed of about 4300 feet per second. During the TV transmission the crew advised that they may possibly be able to take the color television camera into the lunar module with them tomorrow at about 56 hours, 30 minutes, ground elapsed time. They reported that the cables had been checked and are perfectly long enough to take them into the lunar module. During the next hour or so the activity here in Mission Control will be revolving on, getting the crew set up for their rest period and eat period. This will be a very long rest period tonight, scheduled 10 hours. That will begin according to the flight plan, at about 37 hours, ground elapsed time. However, we would anticipate if activities move along as they appear to be at this point, we are somewhat ahead of the flight plan, that perhaps again tonight we would be able to get the crew into their rest period and sleep period a little bit early.

For a brief moment there we had a picture of a somewhat placid Neil Armstrong closing his eyes momentarily. Another crewman to his left, I'm not sure at this point, that I can make out who it was, it did appear it might have been Mike Collins.

SC
Houston, Apollo 11.

CAPCOM
Go ahead 11.

SC
Charlie, is that you.

CAPCOM
That's me, how are you today?

SC
Just fine, how's the old white team today?

CAPCOM
The old white team's bright eyed and bushy tailed. We're ever alert down here.

SC
Ever alert, hey you got any medics down there watching high grade. I'm trying to do some running in place down here and I'm wondering just out of curosity whether it brings my heart rate up.

CAPCOM
Well they will spring into action here momentarily, stand by.

PAO
That was Mike Collins commenting that he was doing some running in place exercises, and we may get a brief view of that a little later on in this transmission if this picture stabilizes and holds still for us.

CAPCOM
Hello 11, we see your heart beat.

SC
(garbled) We're all running in place up here. You wouldn't believe it.

CAPCOM
I'd like to see that sight. Why don't you give us a TV picture of that one.

SC
I think Buz is trying. He got it.

CAPCOM
Okay it's coming in at Goldstone Buz. We don't have it here in the center.

SC
I imagine that didn't help out the PTC very much.

SC
I don't know whether it's the vibration or what it is but it makes the, pitch and yaw rate needles on the FDAI jump up and down a little bit when we jump up and down.

CAPCOM
Rog, Goldstoners say they see you running there Mike.

SC
Okay.

SC
Ask him what he's running from.

CAPCOM
Eleven, Houston. Mike we see about a 96 heart beat now.

SC
Okay, thank you.

SC
Well that's all that's reasonable without getting hot and sweaty.

Goldstone should be getting about the best picture of the earth, we can get, right now Charlie.

CAPCOM
Roger Mike. Thank you much.

SC
We got a little distortion horizontal direction from our damping on our monitor. I wonder if they're getting the same thing.

CAPCOM
Stand by Buzz. I let you know.

SC
I guess it'd be more described as a waviness.

CAPCOM
Goldstone, M & O. Houston, Capcom.

GOLDSTONE M & O
Goldstone, M & O.

CAPCOM
Okay. The crews complaining of some horizontal banding on their monitor. Do you all see that on your picture?

GOLDSTONE
Stand by.

GOLDSTONE
No we don't see it right now. Don't have anything in focus Charlie.

CAPCOM
Roger. He's checking on it. I'll see if they had it earlier. Stand by.

SC
I guess when we were showing the DSKY or when we were showing the earth, might be the better time.

CAPCOM
Okay.

GOLDSTONE
Houston, Capcom Goldstone.

CAPCOM
Go ahead.

GOLDSTONE
Okay. Our TV people confirmed they see this horizontal band.

CAPCOM
Okay.

CAPCOM
11, Houston. The Goldstone TV people also see the banding when same time you all do. Over.

SC
Okay. Would they call it a horizontal waviness from our banding, maybe?

CAPCOM
I'm not talking to him directly. Stand by Buzz. Let me see how they describe it.

CAPCOM
Goldstone M & O, Houston Capcom. Could you put the TV down a little please?

GOLDSTONE
Capcom, Goldstone. Roger.

GOLDSTONE
Houston Capcom, Goldstone M & O Net 1.

CAPCOM
Go.

GOLDSTONE
The TV people do not have access to that one in that area. Suggest we use NET 2 for that purpose.

CAPCOM
Okay. Go into NET 2.

CAPCOM
Hello Apollo 11, Houston. The Goldstone TV guy said that they had some horizontal banding across the upper part of the picture and across the lower part. They would consider the lines just strayed, no waviness at all. Over.

SC
Roger understand. They do think

APOLLO 11 MISSION COMMENTARY    7-17-69     CDT 21:30  -  GET 36:57  -  TAPE 137/2

SC
they do distort vertical lines, though?

CAPCOM
Say again about the vertical lines, Buzz.

SC
Roger. When there's a vertical line, these horizontal bands tends to put small waves in them.

CAPCOM
Roger. I copy. He didn't mention that. Stand by, I'll check again.

CAPCOM
Hello 11, Houston. The Goldstone TV said that when you did a sharp vertical line on the picture, where the horizontal banding goes across it, does appear to bend it slightly. The same as Apollo 10, they said. Looks okay to them. Over.

SC
Okay. Understand it's not our monitor, must be the transmitter or something.

CAPCOM
Roger. I guess so Buzz. We'll have them look into it and see if they can suggest anything.

CAPCOM
Hello Apollo 11, Houston. We've lost our command interface with Goldstone. We'd like you to switch to OMNI DELTA. Over.

SC
Roger. (garble) DELTA.

CAPCOM
Roger.

CAPCOM
Hello Apollo 11, Houston. We'd like you to terminate the O2 purge if you've not done so already and the TV camera people says the lines are inherent in the camera Buzz, and it's something that we expected. Over.

Charlie, how far out can you pick up TV off the OMNI?

CAPCOM
Stand by.

CAPCOM
Apollo 11, Houston. We're just about at the limit where we can get any kind of picture at all on the OMNI on the TV. It - The picture is, I guess, it'd be just almost zero at this point.

SC
Okay, well for this TV program coming up in a couple of hours, you might give some thought to how you want us to stop PTC. If you do, for the best high gain angle, and also it'd be nice if you could stop us at such an attitude that we'd have the earth out of one of our windows.

CAPCOM
Roger, 11. We're thinking about that.

PAO
This is Apollo Control. That concludes the replay of the test transmission from Apollo 11. That transmission occurred about 2 hours prior to the regularly scheduled TV transmission this evening. The crew, apparently, testing out the onboard system, and we received about 52 minutes of intermittant television using the spacecraft OMNI directional antennas. And as you could see, as particularly near the end, this is just - appears to be just about the limit television reception from the OMNI antennas. At the time of the transmission, Apollo 11 was about 121,000 nautical miles from earth. During the replay of that television transmission, we accumulated a very short amount of tape, one or two brief comments from the crew who are in their sleep period at this time. We'll play back that tape conversation for you now.

Hello Apollo 11, Houston. One request the optics switched to 0 and we have a lot of theories of why it maneuvered at 7/10ths a moment ago Mike, but no real definite answer. We'll be back with you later, over.

SC
Okay, no rush, Charlie.

SC
Houston, Apollo 11.

CAPCOM
Roger, Mike I think we can explain that 7/10ths rate. When we - the first half through to show through the VERB 49 so we had a large error between our actual PU and desired PU in roll and with that situation the DAP or the vehicle will roll or maneuver rather at a rate - that is loaded in which was 3/10ths plus 4/10ths rate and it will limit it 4/10ths above the desired rate. So, that is, if we have a large enough angle between the desired and the actual which we did, so therefore the rate was 4/10ths plus 3/10ths which would give you the 7/10ths, over.

SC
Okay, thank you.

CAPCOM

At this time Apollo 11 is 137,219 nautical miles from Earth. The spacecraft is traveling at a speed of 4132 feet per second. Here at Mission Control things have settled down into a rather quiet nightime routine. We said good night to the crew about 36 hours - 36 hours 9 minutes to be exact, a little over a hour ago. We did hear from them once or twice since then and we anticipate that this time are probably getting settled down to begin their 10 hours sleep period.

Houston, Apollo 11. We've got the continent of Africa raising - facing toward us right now, and of course, everything's getting smaller and smaller as time goes on. The Mediterranean is completely clear. The sun looks like it's about to set around Madagascar. The equatorial belt of Africa stands out quite clearly. We're seeing the dark green or a muddy colored green compared to the sandier colors in the southern tip of Africa and, of course, the Sahara shoreline coast of Africa. There's a rather remarkable cloud that appears in the vicinity of the border between Afganistan and Pakistan. It's just about to go into the sunset now. It is casting a very large shadow (garble). The end of the cloud near the tropical conversions clouds all along the equator clearly separates the clockwise and the counterclockwise cloud formation for us.

CAPCOM
Okay, we copy the width of the Persian Gulf, and yes that - all I can give you first hand is a single isolated data point, and that is that it was clear here in Houston this morning. That's a pretty localized observation. As a result of your waste water dump, it looks like the PTC mode has been disturbed somewhat. We're showing you about 20 degrees out in pitch right now on about 6 degrees in yaw which is significantly greater- about twice as much - a little more than twice as much as the deviation you had prior to the waste water dump. We're watching it down here, though, and we'll let you know if we think any corrective action is required. Over.

CAPCOM
I guess the smallest object that you could pick out looking through it would give us a pretty good idea.

Roger. We have been working under the assumption that we would take about an hour for the interference from a waste water dump to dissipate to the point where you can reasonably take star sightings for platform alignment navigation or something of this sort. If you have a spare minute or two, could you comment on the observation conditions now. Over?

Yes. Stand by a minute, Bruce.

CAPCOM
Okay.

SC
My guess would be that a telescope is rather useless, but you can differentiate in the sextant between water droplets and stars by the difference in their motion.

CAPCOM
Okay, Mike. I guess that we've still got - what you are saying is that we've still got a lot of water droplets visible, but you can pick them out and distinguish them in the sextant then.

Right. I think so, but Buzz is looking through it now. Just a second.

Houston, Apollo 11. It looks like at this time the sextant would be quite usable for any alignment. There's actually very few verticals that need to be aligned.

CAPCOM
Roger, Buzz. How about the telescope? Is it useful now?

SC
Well, it's not quite as useful. It doesn't seem to be. Depending on the position of the sun it's got that band that seems to go across the center. I don't think it's because of the waste water particles that it would lack it's effectiveness. Over.

CAPCOM
Roger. What - is this band something that's deposited on the outside of the optics? Over.

SC
Now, it's a reflection from the sun.

CAPCOM
Roger.

SC
The sun bounces off the LM structure. With the LM attached the telescope is just about useless. Those star charts that Ed has provided, I think would be most useful if we had to use the - if for some reason we had to burn through the telescope we could those as a guide for what we're looking at and say, well, that bright blob over there has got to be that star because that's the position we're in, but so far we've not been able to pick out any decent star patterns while docked with the LM using the telescope.

Roger. In Washington, the Senate Finance Committee has approved extension of the Income Tax Surtax, but a Senate vote on the bill apparently seemed remote. In Austin, State Representative Ray Lemmon of Houston has been nominated as the National Director of the American Society for Oceanography. Lemmon has proposed a study of the possibility of establishing an institute of oceanography in Texas. This would be the first such institute on the Western Gulf of Mexico. In Minneapolis, Minnesota, the weather bureau after recapping today's weather showing a high of 88 and a low of 72, has noted "snowfall: none." From St. Petersburg, Florida, comes a radio report from a Norwegian Explorer, Thor Heyerdahl which said that the crew of his papyrus boat RA will sail into Bridgetown, Barbados, despite damage from heavy seas. The crew, however, will sleep on an escort vessel. Norman Baker, navigator of the expedition, said the crew was aboard the RA today repairing damage from storms this past week which split the footing of the mast. Part of the broken mast was jettisoned overboard. The vessel was 725 miles east of Barbados. "It is possible but uncomfortable to sleep aboard the RA," Baker said in the radio report. "But the purpose of our voyage is not a test of strength or human endurance." That is the reason why the crew was spending nights aboard the escort vessel Shenandoah, which rendezvoused with the RA on Tuesday. In sports, the Houston Oilers are showing plenty of enthusiasm in their early preseason workouts at Kerrville and Coach Wally Lemm says he is impressed with the fine group of rookies. National League baseball - was it yesterday - Thursday - St. Louis 11, Philadelphia 3; Montreal 5, over Pittsburgh 4; Atlanta 12, Cincinnati 2; San Franscisco 14, and Los Angeles 13.

with gas in the food bags like the janitor reported?

SC
Well, that's intermittently affirmative, Bruce. We have these 2 hydrogen filters which work fine as long as you don't hook them up to a food bag. But the entry way into the food bag has enough back pressure to cause the filters to start loosing their efficiency. A couple of times I've been tempted to go through that dryout procedure, but we found that simply by leaving the filters alone for a couple of hours, their efficiency seems to be restored.

CAPCOM
Roger, we copy.

SC
Their efficiency ranges anywhere from darn near perfect to terrible just depending on the individual characteristics of the food bags we're putting through it. Some of the food bags are so crumpled near the entry way that there's no way we can work them loose to prevent back pressure.

Oh, okay. You're right.

SC
Okay, it's loose now. Coming down.

CAPCOM
Roger.

CAPCOM
Looks like it's a little bit easier than doing that in the chamber. Over.

SC
You bet. It's the only way it's pretty massive but it goes where you direct it.

CAPCOM
11, Houston. That's beautiful picture now, we've got. We're going to have 12 seconds delaying. Adjust and just bringing it down by the optics now.

SC
Mike must have done a smooth job in that docking. There isn't a dent or a mark on the probe.

CAPCOM
Rog. We're really getting a great picture, here. Over.

CAPCOM
11, Houston. With a 12-foot cable, we estimate you should have about 5 to 6 feet excess when you get the camera into the LM. Over.

SC
Roger.

CAPCOM
We can see the probe now. A correction, the drogue.

SC
Roger.

SC
Okay, drogue removal is coming next.

CAPCOM
Roger. As we suspected.

PAO
Once removal of the drogue is completed, they will have access to the LM hatch and be able to go into the tunnel.

CAPCOM
11, Houston. Now it's a good view of storage area under the couch.

CAPCOM
11, Houston. Looks like it's pretty crowded in there with that drogue. Over.

SC
Oh, it's not really bad. This TV cable is getting in the way.

CAPCOM
We see lots of arms.

CAPCOM
We see lots of arms.

SC
The only problem, Charlie, is these TV stage hands don't know where they stand.

CAPCOM
Well, you got to really have a union card there. We can't really complain too much, I guess.

PAO
This unscheduled televison transmission has now run about 18 minutes, and we have no estimate at this point as to how long it will continue. Mike Collins reported that it would - we would go ahead with the regularly scheduled one when they are in the LM.

CAPCOM
Apollo 11, Houston. Do you have a little white dot in the bottom of your monitor - TV monitor? Over.

SC
Roger. We do.

CAPCOM
Roger. I guess part of the camera's been burnt out down there. These are really beautiful pictures here, Buzz. Real clear.

SC
Okay. We might have got just a little bit of nothing there. Is it just a one small white dot?

CAPCOM
That's affirmative.

PAO
Have a good view here of the computer display and keyboard assembly with the green lights flashing.

SC
We went up in the tunnel checking the roll angle, Charlie, and it's 2.05 degrees.

CAPCOM
Roger. Copy. 2.05 on the roll cal.

SC
And that's a plus.

CAPCOM
Roger. Plus.

PAO
The reference to the roll cal, or roll calibration index marker in the tunnel, which shows how far off exact 0 the 2 vehicles were when the docking occurred.

CAPCOM
11, Houston. The tunnel looks pretty clear to us. Somebody going up there now. Over.

SC
It's Mike checking his connectors up there now.

CAPCOM
Roger.

CAPCOM
11, Houston. The lighting up in there looks very good to us at this time. Over.

SC
I think that's mostly the camera. It's subdued to say the least.

CAPCOM
Roger. It's funny. It's gathering pretty well to us. We see everything quite clearly up in there.

SC
Anyhow, the dock latches look good today just like they did yesterday. Everything up in there looks just fine.

CAPCOM
That sounds fine to us. Over.

PAO
Mike Collins reporting there on the appearance of the latches.

APOLLO 11 MISSION COMMENTARY    7-18-69     CDT 15:57  -  GET 55:25  -  TAPE 175/2

CAPCOM
11, Houston. We can read the decals up there on the LM hatch.

SC
Well, let me move it up and see how much you can read.

CAPCOM
Okay.

CAPCOM
We can see the LM umbilical connection quite well, Buzz. We see you zooming in on one of the decals now. It's - to reset, unlatch handle, latch behind grip and pull back 2 full strokes. That's about all we can make out.

SC
You got an A plus.

CAPCOM
Thank you very much, sir. At least I passed my eye test.

SC
I'm standing six feet from it, Charlie. You can read it better than I can. There's something wrong with your system.

CAPCOM
Roger.

PAO
An interested observer of these amazingly clear pictures coming to us from more than 175,000 miles out in space is Astronaut Gene Cernan, who got a first hand view of some of this same area of the spacecraft during his Apollo 10 flight.

CAPCOM
That's a real good view of the LM hatch handle there, 11. Over.

SC
Roger.

SC
Looks like we'll be ready to go into the LM early if that's okay with you all down there,

CAPCOM
Roger. It's fine with us, Neil. Go ahead anytime you wish. Over.

SC
Okay.

CAPCOM
11, Houston. The white spot you see on your monitor - our TV people say it is a burn spot, but they expect it to dissipate after a couple of hours. Over.

SC
Roger. Thank you.

Okay, the dump valve is actuated.

CAPCOM
Roger, copy, then we see it very clarly. Is that you Buzz with your hand on it?

SC
Yeah.

CAPCOM
11, Houston. We're really amazed at the quality of the picture up in the tunnel. It's really superb, over.

SC
It is considering the amount of light up in there. Hey, we are about to open our hatch now.

CAPCOM
Rog. There is that same guy when you opened up the door, why, he is waiting there for you and he turns the lights on.

SC
How about that. It's like the refrigerator.

PAO
That conversation between Charlie Duke and Mike Collins referring to the automatic light that comes on in the LM when the hatch is opened.

CAPCOM
Buzz, the view by your left shoulder there is so good we can see the ascent engine cover, the velcro on it, and that's' about all we can make out right now. Now we see the helmets, do we?

SC
We don't see anything loose up there.

CAPCOM
Well, great. Looks good to us. We see the helmet storage space.

CAPCOM
11, Houston. We got a view of the PLSS there, off the right of our screen.

CAPCOM
11, Houston. Buzzy already in? Over.

SC
Roger. I'm halfway in, hanging out, or turning around, I guess.

CAPCOM
Roger.

PAO
Buzz Aldrin, reporting that he's halfway into the LM. His view is inside the LM cabin.

CAPCOM
Apollo 11, Houston. We'd like you to read out the LCG reservoir sight level. Over.

SC
Okay. Stand by.

CAPCOM
11, we have a good view of the window there. It looks like the sun is finally coming through the shade.

SC
Yes, I'm afraid it's - we're just about plus z toward the sun.

CAPCOM
That's affirmative. This attitude put both windows right toward the sun - the LM. Over.

SC
Well, that may be good in some ways, but -

CAPCOM
We had a view, Buzz, of the utility light cord. Utility's on.

SC
Yes, let me show you a view looking the other way.

CAPCOM
Roger. And we see right now the utility light or either the flood light up there.

CAPCOM
I think now I see the utility light is still in the stowage bag. Hey, that's a great shot right there. We see you in there. Guess that's Neil and Mike. Better be, anyway.

APOLLO 11 MISSION COMMENTARY    7-18-69     CDT 16:07  -  GET 55:35  -  TAPE 176/2

CAPCOM
We see you waving.

PAO
Buzz Aldrin has apparently carried the camera into the LM with him, showing us Neil Armstrong and Mike Collins back in the CSM.

CAPCOM
11, Houston. That's really a beautiful shot.

CAPCOM
11, Houston. We didn't quite decipher that signal that just came from the CMP.

SC
Just saying hello. On the LCG sight gage, you got about - it looks like - the white mark that's in the plunger is about a quarter to three eighths inch out into the green away from the red. Is that what you like to see? Over.

CAPCOM
Stand by. Right, Buzz; that looks good to us. Thank you much.

SC
It is the white index, is it not, that you're interested in comparing whether it's in the red or green?

CAPCOM
Stand by. That's affirmative, Buzz. It looks good. That's a good reading for us. Over.

SC
Okay.

CAPCOM
We had a shot momentarily - a moment ago of the suit disconnect valve.

SC
I'll open up the windows and see what the lighting condition's going to be like.

CAPCOM
11, Houston. That's a real good view we have of the AOT. You're back there, Buzz, and notice you're taking down one of the window shades. Over.

CAPCOM
The light is superb.

SC
How's the sun coming in? How's the sun coming in from this direction going to affect what you can see?

CAPCOM
It made it really super. The lighting is excellent in the LM right now. We can make out the AOT, the ISA, and the left-hand window- there's a little glare off of that, but the LMP side the - with the shade down it's really excellent. Over.

SC
Well, let's - I'm turned around, why I took the shade off my side first.

CAPCOM
Roger. We copy. The light level for the TV is really excellent. Over.

SC
The lighting in the LM is very nice, just like completely daylight, and everything is just beautiful. A good bit lighter than the tunnel was earlier.

CAPCOM
Roger. We got a good view now of the DEDA and also, Buzz's ATA.

PAO
This ingress to the lunar module came about 40 minutes ahead of the flight plan, and we would presume that the unscheduled TV is perhaps merging with the schedule a little bit early.

SC
Every thing seems to be in place down there.

CAPCOM
Roger, we got the dump valves in view, over.

SC
Roger.

CAPCOM
Eleven, Houston. We see you're removing the ISA now, folding it up, putting it up by the AOT. The instrument pannels are coming into view behind.

SC
Yea, I think probably it'd be best since we've done an SPS burn to put it back over the instrument panel instead of putting it up over the PLSS on the rechart station. Would you care to comment on that one. We can do either, just as easily.

CAPCOM
Stand by we'll have an answer for you momentarily.

CAPCOM
Eleven, Houston. It's really a super shot of the thing displaying.

SC
The vehicle is suprisingly free of any debris floating around, it's very clean.

CAPCOM
Roger.

CAPCOM
Eleven, Houston. It's pretty hard to describe this view. It's really great.

SC
Now you know how we feel.

SC
Okay Neils OCS is about 57, 58 hundred.

CAPCOM
Copy.

SC
And mine is about 58 hundred also.

CAPCOM
Copy.

PAO
Aldrins hand resting on one of the portable life support systems which will be used on the moons surface.

Eleven, Houston. That's a good shot of Neils PLSS there, over.

SC
Yea that's fine.

CAPCOM
Eleven Houston just a moment ago we had a good shot of your PLSS Buz, and the two helmet stowage bags, and now behind your left shoulder Buz, we have your DSKY and the ACA.

PAO
We're not quite sure who's holding the camera at this point. Apparently it's drifting freely inside the cabin. Or more likely attached to some convenient point within the LM cabin.

SC
We're going to go ahead and take all the loose data on back into the command module, Charlie.

CAPCOM
Roger.

This television transmission has now been running about 42 minutes, and the spacecraft now about 176 thousand miles from earth.

CAPCOM
Apollo 11 Houston. Buz it appears that you didn't put on the sun filter and viewing the sun through the AOT, over.

SC
Yea, unfortunately it looks like it's down a little bit more towards (garbled) than I can be able to see in the MT.

CAPCOM
Roger.

SC
We've got a beautiful view of the side of the command module out of the AOT looking in the left rear deton.

CAPCOM
Rog.

SC
I can see the hatch and all the EVA hand rails. First time we've seen the silvery outside of the command module. I can read the letters on the hatch cover, it's a boost cover release, and the big yellow arrow that points toward the opening place where the 20B goes.

CAPCOM
Rog. Great shot now back down into the -

SC
And left on the - -

CAPCOM
Go ahead Buz, over.

SC
Say again.

CAPCOM
I was just saying we got a great shot looking back into the command module.

SC
Okay. And the left decent I can see the rendezvous radar, and I move to the forward detent and that's about all I've got. I'm looking eyeball to eyeball.

CAPCOM
Rog.

PAO
Neil Armstrong has apparently been holding the camera, looking back down through the tunnel it appears now that he's handed the camera to Buz Aldrin. As he is still looking back through the tunnel we see Mike Collins in the background there.

SC
Charlie is there any concern about the duration that we ought to have the window shades open?

CAPCOM
Stand by.

SC
We don't have any circulation in here and it might get a little on the warm side.

CAPCOM
Rog.

SC
We'll put up a couple of hoses in the command module here and get a little circulation going.

Apollo 11, Houston. As far as the window shapes go in this LM is nothing except for crew comfort. I don't think we've got any systems problem. Be sure to put them back up when you egress. Over.

SC
That we will do.

SC
Charlie, I'll give you a view out of the overhead window, back looking at the Command Module, right hand rendezvous window.

CAPCOM
Roger.

CAPCOM
Well we see it now. Thanks a lot Buzz. It's a good view through the over head.

SC
One (garble) is on by the overhead.

CAPCOM
Roger.

CAPCOM
There we go. We've got it now.

SC
There wasn't very much debris in the Command Module or the LM. We found very few loose particles of bolts, nuts and screws and lint Very few in each spacecraft. They were very clean.

CAPCOM
Roger. Sounds good.

CAPCOM
11, Houston. We have a good view out of the rendezvous - correction the overhead window of the LM. We don't see anybody standing back at it though. Over.

SC
Charlie can you see Mike's two eyeballs staring out through the nautical window?

CAPCOM
11, Houston. Stand by. We haven't picked him up yet.

SC
They're looking through a lot of layers of glass.

CAPCOM
11, Houston. We had a slight glimpse of Mike in the rendezvous window at that time. It's pretty murky looking in there though.

SC
Okay. Here he is. I've got him. I've got him on the monitor now.

CAPCOM
Okay. We see him staring back at us now. Hello in there.

CAPCOM
Apollo 11, Houston. Our recommendation to the ISA is to store it back over the instrument panel. Over.

SC
Roger. Will do.

PAO
This transmission has been running about 54 minutes at this point.

CAPCOM
11, Houston. We can make out the markings on the panel. We read system a assent fuel, S in oxidizer. QUADS 1, QUAD 4. It's really unbelievable the definition we're getting down here off that little camera. Over.

CAPCOM
We can even see the barber pole on

We can read the markings on the instruments for the glycol pressure quantity, quantity, TC O2. You can read the scale on the eight ball. Over.

CAPCOM
11, Houston. We seen across these barber pole and we had the Velcro patches back up to the RCS systems now. We can see the markings on the meters, green and red bands, in limits. We see you raised the cover on the abort stage. We don't recommend that.

SC
Yes. We're going to tape that one over.

CAPCOM
Roger.

SC
Going to tape that one over.

CAPCOM
We concur.

SC
The restraints in here do a pretty good job of pulling my pants down.

CAPCOM

At this point, we've had to take the color down momentarily. We've run out of tape in the color conversion recorder. We estimate we'll have the black and white for about 5 minutes while the tape changes in process and then continue to convert in color after that point.

CAPCOM
Roger, stand by. We'll have an answer.

CAPCOM
11, Houston. On that TV, our commentary - The monitor I was looking at was delayed about 12 seconds, 12 to 15 seconds while it went through our color converter. It was probably - You thought I was praising, but we were looking at it 15 seconds after you broadcasted. 11, Houston.

SC
We understood that, Charlie.

CAPCOM
Okay, on the LM cameras, we'd like you to do it on LOI day with the LM power. Over.

SC
Okay, that's what we'll do.

PAO
The black and white view that you're seeing now is the unconverted color pictures that comes down from the spacecraft. The flicker, of course, is taken out in the conversion process. We've now been receiving television pictures from the spacecraft for about 1 hour.

SC
Checklist stowage packet, it's, got a 16-millimeter camera in it and it's got this little cylinder and I guess - I don't understand what it is. Maybe you can tell us.

CAPCOM
Roger. Stand by. We can't figure it out either.

SC
It's got an arrow on the back and it says "turn", but I'm afraid to turn it.

CAPCOM
11, your friendly geologist says it's the camera crank. Excuse me, for the 16 sequence camera if it jams. Over.

SC
All very well. Thank you.

Now we're back with the color.

CAPCOM
The shades couldn't quite hack it, there, Buzz. Over.

SC
Houston, 11. Are you still getting high bit rate off the OMNI's at this distance?

CAPCOM
Stand by, Mike.

You' re welcome.

CAPCOM
Apollo 11, Houston. Neil, with this attitude, you look like you're about 12 feet along.

SC
It seems like I always find myself upside-down in whatever I'm doing around here.

CAPCOM
Apollo 11, Houston. Could you give us a few comments on your crew comfort with the CSM hoses moving you around? Over.

SC
Well, it's picking up a little bit of circulation in here.

CAPCOM
What do you estimate the temperature is, Buzz? Over.

SC
I'd say maybe 73, 75.

CAPCOM
Rog.

SC
It's hard to tell at this density and pressure of gas, but comfort level is about the same as the command module. It was warmer, or stuffier when we first got in, but it seems to be improving.

CAPCOM
Houston copies that.

CAPCOM
11, Houston.

SC
You may be able to see some -

CAPCOM
Go ahead.

SC
Some particles jumping around on your screen. That's just dust particles that are being eliminated by sun shafting in the window.

I can just barely see the hand rail on the front porch from this position on the right hand window.

CAPCOM
Roger.

CAPCOM
Eleven, Houston. Our view of the panel eleven is, gets brighter then darker. Are you changing the F-stop at all, over.

SC
Now what's happening is we get pretty close to the window now and then drives the automatic light control into the stop I think.

CAPCOM
I think that's right.

SC
Yea I had the switch on outside while I was going through the overhead window. That may be what's contributing to some of it.

CAPCOM
Roger. Eleven, Houston, we seem to be picking up a few more dust particles now. We see them quite clearly on the screen now, over.

SC
Yea I'm choking on one ever so often.

CAPCOM
Eleven, Houston. Your show is going out to the US now. We're about to get this satelite up. It'll be transmitted to some other countries after that, over.

SC
Roger. I'm checking out this window bracket. Where I'll be putting it for the EVA pictures of Neil going down the ladder.

CAPCOM
Roger.

SC
Apollo 11, Houston. We keep mrveling about the color and the clear of your picture. It's really difficult to describe. It's just perfect, over.

CAPCOM
And Eleven, it doesn't look like you're having too much trouble with that bracket up there, Buzz.

SC
Roger, those new knobs really make it easy to twist the thing and get it cinched down quite tight.

CAPCOM
Rog.

CAPCOM
Eleven, Houston. Buzz, how does the alignment look?

SC
It looks pretty good as well as I can tell without the gear extended. I can't get a real definitive answer, but you couldn't fix it any place to see much more out of the window without holding it for the whole time.

CAPCOM
Roger looks like to us it's going to work real well.

SC
Give me enough room to - Yea I think so.

CAPCOM
Buzz we see you putting your window guard in place there and back up to the ISA now.

SC
Houston ask if they know if the 90 degree bracket can be stowed in the commanders stowage assembly.

SC
Our monitor shows pretty good, clear pictures from this angle. Alley found the 90 degree bracket.

That's about the position we'll be putting the camera in after the initial descend on the ladder, and it'll be taken 1 frame per second for most of the EVA.

CAPCOM
Houston copies out.

CAPCOM
That's a real good view of that camera.

SC
Our monitor is a little bit wavey, so it's hard for us to tell when we're - when we've got a steady picture for you.

CAPCOM
11, we have no complaints at all. We don't see that waviness on our picture. It's just really great. Over.

SC
Do the edges of the window look like straight lines to you?

CAPCOM
That's affirmative.

SC
Okay, they don't in our monitor and that leads us to make some corrections to the camera, which probably aren't required sometime.

CAPCOM
Buzz, we have no complaints at all. It's a magnificent picture.

PAO
We've been receiving television now from the spacecraft for about an hour and 20 minutes. Apollo 11 presently 177,000 miles from earth.

CAPCOM
What was that, Buzz, you're chasing now?

SC
That was me picking up some particles of paint that were floating through the air in front of our camera, there.

CAPCOM
Rog. Now we got it. It appears to us that Neil's to check the velcro map there.

CAPCOM
Okay Buzz, we see the card up now.

SC
Okay, for those of you that don't know, this is where we log most of our data for each of the LM maneuvers and we have another card like this but the timeline broke that we had layed down on the table in front of the - down there at this play keyboard, and it's on this timeline that we have all our procedures. And we obviously have to hold these in place in zero "G" so we make use of the velcro patches on the back and on the table so we can attach these down here and then we just turn the pages over when we go to a new sequences in our timeline of procedures.

CAPCOM

CAPCOM
11, that's real good camera work.

SC
That'll be the most unusual position a cameraman's ever had, hanging by his toes from a tunnel and taking the picture upside down.

CAPCOM
Roger. You're doing a super job. We got a good view of the cross pointer, there. We had a good view of the tapemeter.

SC
We're giving you a picture now, of the floor of the cabin. I think you can see the - one of the two portable life support systems backpacks here in the center, and on each side, we have two helmet visors. I'll remove one of them and show you a little closer view of what this looks like.

CAPCOM
Roger.

SC
Inside the helmet visors, are the EVA gloves, with the blue tips. I'm about to take those out now.

CAPCOM

SC
Okay. You did say this was going out now, didn't you?

CAPCOM
Stand by. I think so.

CAPCOM

It's like old home week Charlie to get back into the LM again.

CAPCOM
Roger. I can imagine.

SC
It's a ... from the bottom of the LM to the aft bulkhead of the Command Module. Must be about - or 16, 20 feet. It's not a disorienting one at all but it's most interesting to contemplate just pushing off from one and bounding on into the other vehicle all the way through the tunnel.

CAPCOM
Roger. Must be some experience. Is Collins going to go in and look around?

SC
We're willing to let him go but he hasn't come up with the price of the ticket yet.

CAPCOM
Roger. I'd advised him to keep his hands off the switches.

SC
If I can get him to keep his hands off my DSKY, it'd be a fair swap.

CAPCOM
Roger.

SC
That's why I've been eating so much today. I haven't had anything to do today. He won't let me touch it any more.

It appears now that we have a view of earth out the window.

CAPCOM
11, Houston. If that's not the earth, we're in trouble.

SC
That's the earth and we have a very good view of it. Today they're a few more cloudbands on than yesterday when we came down to you but it's a beautiful sight.

PAO
That description from Neil Armstrong?

SC
We had some horizontal banding in our TV monitor. Are we transmitting that to you or do you have a clear picture?

CAPCOM
Neil we have a very clear picture. The only thing that we see is a little white dot in the bottom of our screen which our TV guy says is an apparently burned out spot in the camera but it should come back. Over.

No. Those are the same 3 ones that we have.

Okay.

How far out are we now, Charlie?

That's the way it looks Charlie. Same as yesterday.

CAPCOM
Roger.

SC
Just keep the Pacific Ocean nice and clear and calm on splash day is all we ask.

SC
Charlie. I'd like to say hello to all my fellow scouts and scouters at Farragut State Park in Idaho having a national jamboree there this week and Apollo 11 like to send them best wishes.

CAPCOM
Thank you Apollo 11. I'm sure that if they didn't hear that, they'll get the word through the news, so they'll appreciate that.

CAPCOM

Hello Apollo 11, Houston. Could you give us an idea of about how long it will be before you start close - closing the LM back up? Over.

SC
We got a little more work to do up here - Charlie, we are going to make sure that we have everything transferred around and stowed the way we want it. Try to get a little bit ahead on tomorrow's timeline. I suppose we could be out of there in another half hour or so if it was necessary.

CAPCOM
Roger, Neil. We are not trying to push you. We are just trying to get an idea of about water dumps and about starting up the PTC again. Take your sweet time over.

SC
Okay, we would like - to - get a flight plan update from you for the next couple of hours here. When you think what the various constraints might be and what - what order you might like us to do things.

CAPCOM
Roger, standby, we'll have that to you in a moment.

PAO
This is Apollo Control at 56 hours 51 minutes. Buzz Aldrin has now been in the lunar module for a little over an hour and 13 minutes. We estimate that Neil Armstrong has perhaps been in the LM about 15 or 20 minutes less than that. Due to the length of that television transmission, the change of shift press conference has been cancelled. The particpants were unable to wait for the duration of the press conference and with other duties and the press conference has been cancelled. At 56 hours 52 minutes, this is Apollo Control.

Okay. Fine.

PAO
This is Apollo Control at 57 hours, 3 minutes. The decision as you heard relayed up to the crew there, that we would go into the passive thermal control mode with the spacecraft in a slow roll at 58 hours in the flight plan. I would rule out further television for today. I would also like to repeat that the change of shift press conference for the previous shift was cancelled due to the length of that television transmission, and we do expect to have a change of shift briefing following this shift probably between 11:30 and 12:pm CDT. At the present time, Apollo 11 is 178,236 nautical miles from Earth, and the velocity has dropped down now to 3146 feet per second. At 57 hours, 4 minutes, this is Mission Control, Houston.

This is Apollo Control at 57 hours 44 minutes. We've had no further reports from the crew to indicate whether or not Neil Armstrong and Buzz Aldrin have returned to the command module. And I guess that would answer our question. Neil Armstrong reporting that they are finished with their work in the LM, will be coming out shortly. Apollo 11 is now 179,490 nautical miles from earth. Traveling at a speed of 3,121 feet per second. In a little less than 3 hours, we'll pass a milestone of sorts, as the spacecraft passes into the lunar sphere of influence. And what we mean by that, is that at that point, the spacecraft will be under the dominant influence of the moon's gravity. The moon's gravitational force will have the predominant effect on the trajectory of the spacecraft. And at that point, our displays in Mission Control monitoring velocity and altitude will switch from earth reference to moon reference. We'll then begin monitoring the progress of the spacecraft as it continues to accelerate toward the moon. At 57 hours 46 minutes, this is Apollo Control.

Hello Apollo 11, Houston. We're standing by to watch your startup on the PTC at any time. You can start off at the verb 49. Over.

This is Apollo Control. That was Neil Armstrong reporting that they are now reinstalling the probe and drogue, which is just about on the flight plan schedule, and they reported that they would be putting the spacecraft in a slow roll shortly to maintain passive thermal control. In that mode the spacecraft rotates at the rate of about 3 revolutions per hour to maintain even heating. We have a precise time on that sphere of influence change, the point of which the moon - for calculation purposes here. Mission Control, comes under the predominate influence - the spacecraft comes under the predominate influence of the moon's gravitational field, and we now calculate that that will occur at 61 hours, 39 minutes, 55 seconds, ground elapsed time.

Over.

Okay, if any of those in the flight plan. The secondary radiator, for example.

This is Apollo Control at 59 hours, 9 minutes. Apollo 11 now 182,000 nautical miles from Earth, and the velocity down to 3072 feet per second. We've had very little conversation from the spacecraft in the past 40 minutes or so. At this time the flight plan calls for the crew to be getting ready to begin their eat period. That would be followed by a 9 hour rest period. We have one change to the flight plan to pass along. The television transmission which had been scheduled at 100 hours, 20 minutes to 100 hours, 50 minutes in the flight plan has been deleted. This transmission was to have occurred during the formation flying prior to the powered descent to the lunar surface. The decision to delete the TV transmission from the flight plan was made due to a lack of available satelite channels to relay the signal from the tracking site of Madrid to Houston for conversion. The intermittent music that we're getting is apparently coming from the spacecraft. The crew has onboard portable tape recorders with music on the tapes. As they store their own comments on the tape, the music of course is erased, and apparently the music is triggering the VOX operated microphones and we're getting intermittent music down from the spacecraft.

Houston, Apollo 11, ready to copy your update.

CAPCOM
Roger, stand by.

CAPCOM
Okay Buzz, the first item, is that we have indications that your landing sight obliques are not in the proper position. If you will check we think that the intermediate scale landing sight oblique is stowed in the CSM lunar land mark book. We think that the large scale, landing sight oblique is stowed in the back of the LM lunar surface map book, over.

SC
I think I heard you Charlie, but I'm not sure that I understand.

CAPCOM
Roger, according to our storage list the landing sight oblique should be in the transfer bag. In the back up set of data, the intermediate scale oblique is in the CSM lunar landmark book and the large scale oblique is in the back of the LM lunar surface map book, and that's the reason we think that they might be, not where you think they are, over.

SC
Okay, we've got three obieques. The last one is one I asked for recently. It's just a blow up of the second one. The first one is one that's got dotted lines on it, indicating hidden view and 50 degree LPD, and all three of those are in the transfer book, over.

CAPCOM
Roger, fine. We were wrong in our back up set. We had those out of place. Looks like the on board data is good. We just wanted to let you check on that one. We have an update on the APS DIPS fuel cord, that you place on the panel. It's a typo error. If you'll break out that little card, we've got to correct that typo error, over.

CAPCOM
Okay, Buzz. Last entry is down under RCS and it is a typo error under the three - in the line three axis attitude control. We proceed to the right at PDI plus 05 you'll see one axis. The line goes all the way to low gate to touchdown. That's incorrect. The line should stop under 5 minutes to low gate, over.

SC
Okay, we are stopping at it 5 minutes to low gate.

CAPCOM
That's affirm. That completes that card. The rest of the update are just really for your information based on our 58 hour platform - look at the platform. We are really in good shape. Your gyros have almost no drift in them since - plotted update we were looking at X of a minus 2.24 MERU, Y of . plus .87 Z of minus .11. Since the update, which was based on the 52 hour P52, I believe. We gave you a X drift of plus .79, yaw of plus 1.06, Z of plus .02 MERU. I see between the 52 hour and the 57 hour alignments work did not really give us enough time to get a real good, completely valid update on the drift check. So we're real satisfied with the way the gyros are looking. The PIPA'S are looking great also. We are in real good shape with those also, over.

CAPCOM
Roger, thank you Mike, could you give us some help? This PTC is strange, it's not like anything we've seen before. We were wondering if you'all have had any events of any odd data that could help us out, over.

SC
I didn't understand that. Say again.

CAPCOM
Roger, we're looking at a, sort of a funny looking PTC. We've already drifted out to 70 degrees in pitch and we're wondering if you all had any vents or any such thing as that, that could have caused us to pick up these rates to drive us off, over.

SC
Negative, Charlie. We don't know of anything.

Unless it's got something to do with that entry from the position that we want to be in. I don't know.

CAPCOM
Roger, when we started off it looked real fine to us, now it's drifting off with a funny pattern that we haven't seen previously on a flight, and we're just trying to figure out, I think we'll probably start it over again. We'll be with you momentarily, over.

SC
Okay.

CAPCOM
Apollo 11 Houston. We hate to say it, but we'd like to terminate this PTC and start over again. We have no assurance that we're going to get it through the sleep period. With this funny configuration, or funny pattern. We'd like you to stop it now and go back to pitch 090 yaw 0 and roll, whatever you stop on, over.

PAO
This is Apollo Control at 59 hours 57 minutes. A few moments ago you heard Capcom Charlie Duke advise the crew to terminate the passive thermal control mode that they are presently in and reestablish the three revolution per hour roll rate about the spacecraft longitudal axis that is used for thermal control. We had noticed a unexplained deviation from the attitude that the spacecraft was set up in. In this roll mode ideally it would roll about the longitudal axis with very little wobble and if wobble is introduced for one reason or another, the reaction control system jets would come on as soon as the motion out of the prescribed plane had ocurred and gone beyond prescribed limits, in this case 30 degrees to correct. The jet firings on past missions do tend to disturb the crews sleep. Rather than have the reaction control system jets come on during the night and perhaps have to awaken the crew to reestablish the passive thermal control at that time we elected to correct it now.

At this time, Apollo 11 is 183,544 nautical miles from earth and the velocity, holding fairly constant now, at about 3042 feet per second. It's been moving down towards 3000 feet per second and seems to be leveling off somewhat.

This is Apollo Control at 60 hours 37 minutes. We said good bye - goodnight to the crew about 10 minutes ago. We expect that they will be settling down their rest period shortly. And at the present time, Apollo 11 is 184,600 nautical miles from earth. The spacecraft velocity is presently 3,023 feet per second. I understand there has been some interest in a comment made by Neil Armstrong during the television transmission about the EVA floodlight. Armstrong's remark was that the mast which the light is mounted on, appeared charred. He reported that the light works but had apparently the mast that supported it had apparently been damaged during the launch phase. This light would be used in the event of a contingency EVA. It would have no function in a normal mission such as we are presently flying. And in the event that a extravehicular activity was necessary for transfer of the crew from the LM into the command service module, the light would be an aid in providing exterior lighting of the hand rails, but would - repeat, that it'd have no function in a normal mission and the charring which Armstrong reported is not considered significant at this time. We don't expect to have any further conversation with the crew. We will continue to record any remarks that we get and play those back. The passive thermal control mode, which was reestablished, appears to be functioning well at this time and all spacecraft systems are functioning normally. At 100 - rather 60 hours 39 minutes, this is Apollo Control, Houston.

Okay. Did it look like it was all right and just all of a sudden start diverting?

CAPCOM
Negative, if you look at the plot which we'll save for you and let you see it post flight. It started off immediately on the first rev and just spiraled out to about oh, 20 to 20 degrees in pitch, and then it seemed to be setting up a spiral around an off set pitch point of about 20 degrees off from 90 degrees, but we didn't want to take a chance that it would become stable at that point. We thought it might diverge so we told you and started over again, over.

This is Apollo Control at 61 hours, 39 minutes. We've had no further conversation with the crew since our last report. Flight Surgeon says there is no indication at this time that they have begun to sleep, but we expect they'll be getting to sleep here shortly. Coming up in less than 10 seconds now, we'll be crossing into the sphere of influence of the moon. A computational changeover will be made here in Mission Control. At this point as the moon's gravitational force becomes the dominant effect on the spacecraft trajectory, and our displays will shift from Earth reference to moon reference. At that point, which occurred a few seconds ago, the spacecraft was at a distance of 186,437 nautical miles from Earth, and 33,822 nautical miles from the moon. The velocity with respect to the Earth was 2990 feet per second, and with respect to the moon, about 3272 feet per second. The passive thermal control mode that was set up for the second time by the crew appears to be holding well at this point, and all spacecraft systems are functioning normally.

Midcourse correction burn number 4 has been deleted from the Flight Plan on the recommendation to Flight Director Glynn Lunney from the Flight Dynamics Officer, Jay Green. The maneuver, had it been carried out as planned, would be in the neighborhood of one-half foot per second velocity change.

That is if no maneuver is made. The spacecraft cabin pressure now holding at 4.7 pounds per square inch. Temperature 60 degrees F. The planned sleep period has another hour and one-half to go but as mentioned earlier it will likely run another couple hours in as much as midcourse correction burn number 4 will not be made and the crew will not have to spend the time preparing to do the burn, align the platform and do all the chores necessary for doing a maneuver of this sort.

Okay, 11. It turns out that the engine performance during both of your burns so far this mission has been the same as it was on engine acceptance tests.

We expect single bank operation to be 90 - that is 90 psi on the gage with an actual chamber pressure of 95 psi. In dual bank operation the chamber pressure is 94 psi on the gage with an actual of 99 psi. 80 psi on the gage onboard correlates to 83 psi actual, and we recommend that you stick to LOI termination cue of 80 psi on the gage - that is no change to the mission rules.

And Houston. I suggest that along the ecliptic line we can see - throwing the light out to 2 lunar diameters from this location. The bright light only extends out about - about an eight to a quarter of the lunar radius.

CAPCOM
Roger. Understand that you can see the corona approximately 200 solar diameters out along the ecliptic, and the bright light extends out approximately 1/8 to I quarter lunar radius. Over.

SC
That's 2 lunar- 2 lunar diameters along the ecliptic in the bright part, right, a quarter to an eights of a lunar radius out, and that's perpendicular to the ecliptic line on the south pole.

CAPCOM

SC
Houston, it's been a real change for us. Now we are able to see stars again and recognize constellations for the first time on the trip. The sky is full of stars, just like the nights out on earth. But all the way here, we have just been able to see stars occasionally and perhaps trough the monoculars, but not recognize any star pattern.

CAPCOM
I guess it has turned into night up there early, hasn't it?

SC
Really has.

PAO
This is Apollo Control at 72 hours, 7 minutes. Apollo 11 is 9761 nautical miles from the moon, velocity 4217 feet per second. Weight 9612 pounds.

CAPCOM
Apollo 11, this is Houston. How do you read? Over.

SC
Okay. We went to high gain. Looks like you had a little trouble getting signal strength there.

CAPCOM
Roger. We missed the OMNI switch there. Over.

SC
All right. On the secondary loop check when we went to flow on secondary radiators, the quantity dropped from 40 percent down to 36 in the first 10 seconds and then stabilized at 36 for the remainder of the 30 seconds.

CAPCOM
Apollo 11, this is Houston. We believe that is the normal system of operation. The radiators are expected to be very cold right now and apparently the decrease is always due to contraction in the fluid. Over.

SC
Okay. We will go ahead with the procedure just as though there were no decrease in accumulated quantity. Right?

CAPCOM
Roger. Press on.

SC
Houston, the secondary radiator flow check is complete and satisfactory.

CAPCOM
Houston. Roger. Out.

SC
And that is a good deal because we don't have to have any meetings about whether we are going to do it or don't do it anymore.

CAPCOM
Apollo 11, this is Houston. If you have a minute or so free, we can read you up the morning news here.

SC
Go right, ahead, let's hear it.

CAPCOM
Roger, hot from the wires of the MSC Public Affairs Office especially prepared for the crew of Apollo 11.

CAPCOM
First off, it looks like it's going to be impossible to get away from the fact that you guys are dominating all the news back here on Earth. Even Pravda in Russia is headlining the mission and calls Neil, "The Czar of the Ship." I think maybe they got the wrong mission. West Germany has declared Monday to be "Apollo Day." school children in Bavaria have been given the day off. Post Office clerks have been encouraged to bring radios to work and Frankfurt is installing TV sets in public places. BBC in London is considering a special radio alarm system to call people to their TV sets in case there is a change in the EVA time on the moon. And in Italy, Pope Paul VI has arranged for a special color TV circuit at his summer residence in order to watch you, even though Italian television is still black and white. Back here in Houston, your three wives and children got together for lunch yesterday at Buzz's house. And according to Pat it turned out to be a gabfest. The children swam and did some high jumping over at Buzz's bamboo pole. In Moscow, space engineer Anatoly Koritsky, was quoted by Tass as saying that Luna 15 could accomplish everything that has been done by earlier Luna spacecraft. This was taken by he press to mean Luna 15 could investigate the gravitational fields, photograph the moon and go down to the surface to scoop up a bit for analysis. Even the kids at camp got into the news when Mike, Jr. was quoted as replying "yeah" when somebody asked him if his daddy was going to be in history - then after a short pause he asked, "What is history?" In Washington, President Nixon is planning to use his executive power to streamline the Interstate Commerce Commission. According to industry sources, it was reported Nixon would trim the commission from 11 to 7 members by not making new appointments. And the big news around Houston today concerns the Astros. In the Sports World the Houston Astros rallied in the 9th inning at Cincinnati to dump the Reds 7 to 4. Going into the 9th however, things looked pretty bleak. The Astros were trailing 4 to 3. Then with one out Jesus Aiou stroked a single to the right field. John Edwards hit another single to the right, Sandy Valdespino hit a double to bring in the tying run. Julio Gotay was walked and Joe Morgan dropped a bunt for the game winning play. A wild throw to the plate allowed another run to score. Then a sacrifice fly by Denis Menke Brought in the final run. They really came through in the 9th. And other games in the National League.

SC
Yeah, those Astros have really been catching those flys since they put a roof on the stadium.

APOLLO 11 MISSION COMMENTARY    7-19-69     CDT 9:01  -  GET 72:29  -  TAPE 217/2

CAPCOM
Good work. In other games in the National League, New York beat Montreal 5 to 2; Pittsburgh beat St. Louis 4 to 1; and Atlanta over San Diego in the first game of a double header 6 to 2. Im the American League, Detroit beat Cleveland 4 to nothing; New York trounced Washington 5 to nothing; Baltimore out hit - Boston out hit Baltimore to score 6 runs to the Orioles' 2; and Chicago beat Kansas City 6 to 1. Okay, in golf world, Tommy Jacobs, infrequent competitor in recent years took the lead in the Philadelphia Golf Classic yesterday. His second round score was 139. You might be interested in knowing, since you are already on the way, that a Houston astrologer, Ruby Graham says that all the signs are right for your trip to the moon. She says that Neil is clever, Mike has good judgement, and Buzz can work out intricate problems. She also says Neil tends to see the world through rose colored glasses, but he is always ready to help the afflicted or distressed. Neil, you are also supposed to have quote, "intuition that enables you to interpret life with feeling," unquote. Buzz is to be very sociable and cannot bear to be alone in addition to having excellent critical ability. Since she didn't know what hour Mike was born, she has decided that he either has the same attributes as Neil or he is inventive with an unconventional attitude that might seem eccentric to the unimaginative. And last but not -

SC
Who said all that? (laughter)

CAPCOM
Ruby Graham, an astrologer here in Houston. Now that we've got a check with Flight Operations for all the signs of the mission, and then we, of course, had to make sure that everything was really all set.

CAPCOM
Okay, following Tommy Jacobs, we have a hot smoking word from a Houston astrologer by the name of Ruby Graham. She say that all the signs are right for your trip to the moon. Neil is clever, Mike has good judgement, and Buzz can work out intricate problems. She also says Neil tends to see the world through rose colored glasses, but he is always ready to help the afflicted and distressed.

This is Apollo Control at 75 hours 26 minutes. We're 15 minutes away from loss of signal. Apollo 11 is 9066 miles from the Moon, velocity 6511 feet per second. We're 23 minutes away from the LOI burn.

PAO
Flight Director Cliff Charlesworth polling flight controllers for the GO/NO-GO status for LOI now.

CAPCOM
Apollo 11, this is Houston. Over.

SC
Roger, go ahead Houston, Apollo 11.

CAPCOM
11, this is Houston. You are GO for LOI. Over.

SC
Roger, GO for LOI.

CAPCOM
And we're showing about 10 minutes and 30 seconds to LOS. I would like to remind you to enable the BD roll on the auto RCS switches. Over.

SC
Roger, and confirm you want PG on low going over the hill. Over.

CAPCOM
That's affirmative, 11.

SC
Roger.

PAO
That was Buzz Aldrin confirming the GO.

SC
If you want to, I'll put it back to HIGH until just before LOS. Over.

CAPCOM
Negative 11. LOW is okay for now. Over.

SC
Roger.

SC
Houston, do you want to give me a time check, please?

CAPCOM
Roger. I'll give you a mark at 13 minutes and 30 seconds to ignition.

SC
Okay, and then a GET, please.

CAPCOM
Stand by a minute.

CAPCOM
I'll give you a time hack on the GET at 75 hours 37 minutes and I'll show you a bias at about a second and a half to allow for the time of flight.

SC
Okay.

CAPCOM
Stand by. Mark, 75 hours 37 minutes GET.

SC
Thank you.

CAPCOM
And I'll give you a time hack on time to ignition at 12 minutes to ignition. Over.

SC
Okay.

CAPCOM
Stand by for a MARK at TIG minus 12. MARK TIG minus 12.

SC
You were right on, Bruce, thank you.

CAPCOM
Roger, out.

PAO
We are 3 minutes away from loss of signal. Apollo 11 is 425 nautical miles from the Moon, velocity 7368 feet per second, weight 96,012 pounds.

CAPCOM

CAPCOM
Apollo 11, this is Houston. All your systems are looking good going around the corner and we'll see you on the other side. Over.

SC
Roger. Everything looks okay up here.

APOLLO 11 MISSION COMMENTARY    7-19-69     CDT 11:58  -  GET 75:26  -  TAPE 228/2

CAPCOM
Roger, out.

PAO
And we've had loss of signal as Apollo 11 goes behind the Moon. We were showing a distance to the Moon of 309 nautical miles at LOS, velocity 7664 feet per second. Weight was 96,012 pounds. We're 7 minutes 45 seconds away from the LOI number 1 burn, which will take place behind the Moon out of communications. Here in the Control Center 2 members of the backup crew, Bill Anders and Jim Lovell, have joined Bruce McCandless at the CAPCOM console. Fred Haise, the third member of the backup crew, has just come in, too, and Deke Slayton, Director of Flight Crew Operations, is at that console. The viewing room is filling up. Among those we noticed on the front row in the viewing room are Astronauts Tom Stafford, John Glenn, Gene Cernan, Dave Scott, Al Worden, and Jack Swigert. With a good lunar orbit insertion burn the Madrid station should acquire Apollo 11 at 76 hours 15 minutes 29 seconds. Aquisition time for no burn 76 hours 05 minutes 30 seconds.

PAO
This is Apollo Control at 75 hours, 49 minutes. Apollo 11 should have started this long burn duration 6 minutes, 2 seconds, DELTA V 2917 feet per second. Given that burn we expect an orbit of 61 by 169.2 nautical miles. We're 24 and one-half minutes away from acquisition of signal with a good burn. The clock has not yet started counting for the other acquisition time. We'll take this lying down now and come back just prior to the acquisition in time for no burn. This is Mission Control, Houston.

PAO
- and we'll stand by.

We are passed the burn acquisition now and we have received no signal.

PAO
It's very quiet here in the control room. Most of the controllers seated at their consoles, a few standing up, but very quiet.

PAO
We're 7 minutes from acquisition time.

PAO
If Apollo 11 achieved only a partial burn, we could receive a signal any time so we will continue to stay up until acquisition time of 76 hours, 15 minutes, 29 seconds. That time is the initial acquisition time, but it could take a little longer to lock onto the signal for voice communications. We are 4 minutes away now.

PAO
There are a few conversations taking place here in the control room, but not very many. Most of the people are waiting quietly, watching and listening. Not talking.

PAO
That noise is just bring up the system. We have not acquired a signal. We're a minute and one-half away from acquisition time.

PAO
30 seconds.

PAO
Madrid AOS, Madrid AOS.

PAO
Telemetry indicates that the crew is working on the antenna angles to bring the high gain antenna to bear.

SC
(Spacecraft signal very weak - inaudible)

CAPCOM
Apollo 11, this is Houston. Are you in the process of acquiring high gain antenna? Over.

CAPCOM
Apollo 11, Apollo 11, this is Houston. How do you read?

SC
Read you loud and clear, Houston.

CAPCOM
Roger. Reading you the same now. Could you repeat your burn status report. We copied the residuals burn time and that was about it. Send the whole thing again, please.

SC
They were like perfect. DELTA T 0, burn time 557, ten values on the angles, BGX minus .1, BGY minus .1, BGZ plus .1, no trim, minus 6.8 on DELTA VC, fuel was 38.8, OX 39.0 plus 50 on balance, we ran an increase on the PUGS, NOUN 44, show us in a 60.9 by 169.9.

CAPCOM
Roger, we copy your burn status report, and the spacecraft is looking good to us on telemetry.

SC
(garble)

PAO
That burn report was by Neil Armstrong.

APOLLO 11 MISSION COMMENTARY    7-19-69     CDT 12:55  -  GET 76:23  -  TAPE 232/1

PAO
This is Apollo Control. We're showing spacecraft weight in lunar orbit of 72,004 pounds.

SC
Apollo 11. We're getting this first view of the landing approach. This time we are going over the Taruntius crater and the pictures and maps brought back by Apollos 8 and 10 give us a very good preview of what to look at here. It looks very much like the pictures, but like the difference between watching a real football game and watching it on TV - no substitute for actually being here.

CAPCOM
Roger. We concur and we surely wish we could see it first hand, also.

PAO
That was Neil Armstrong.

SC
We're going over the Messier series of craters right at the time, looking vertically down on them and Messier A we can see a good size blocks in the bottom of the crater. I don't know what the altitude is now but that indicates that those are pretty good size blocks.

CAPCOM
Okay. Just roughly it looks like you are about 120 miles or 130 miles right now. Make that 127 miles.

SC
We're approaching PDI point now, over.

SC
There's Secchi in sight.

SC
We're'going over Mt. Marilyn at the present time and its ignition point.

CAPCOM
Roger. Thank you. And our preliminary tracking data for the first few minutes shows you in a 61.6 by 169.5 orbit over.

SC
Roger.

CAPCOM
And Jim is smiling.

CAPCOM
Apollo 11, this is Houston. Over.

SC
Go ahead.

CAPCOM
11, Houston. During your SPS burn as played back on tape down here, we've observed the nitrogen tank BRAVO pressure in the SPS system dropping a little bit more than we anticipated. It's holding steady right now. We'll continue to watch it and keep you posted if anything comes up. Over.

SC
Roger. Thank you.

CAPCOM
Right. And it has held - -

SC
Currently going over mascon map.

CAPCOM
Okay.

SC
And Boothill, Duke Island, Sidewinder, looking at mass one W that's the yaw round checkpoint, and just coming into the terminator at - at the terminator it's ash and gray. If you get further away from the terminator, it gets to he a lighter gray, and as you get closer to the subsolar point, you can definitely see browns and tans on the ground according to the last Apollo 11 observation anyway.

CAPCOM
Roger, 11. We're recording your comments for posterity.

SC
Okay.

PAO
And again, that was Neil Armstrong with the report.

SC
In the background do they accuse us of being compromisers?

SC
And landing site is well into the dark here. I don't think we're going to be able to see anything of the landing site this early.

CAPCOM
Apollo 11, this is Houston. When you have a free minute, could you give us your onboard readout of N2 tank BRAVO, please, and we'd like to make sure you understand that ever since you stopped thrusting with the SPS the temperature in the tank has remained steady. Over. Make that the pressures remained steady.

SC
Rog. We understand tank pressure has stayed steady. Thank you.

SC
Roger. We're showing the N2 tank pressure and the tank BRAVO to be 1960, something like that, and alpha is, oh, about 2250. Over.

CAPCOM
Roger. We show 2249 in alpha and 1946 down here.

SC
All right.

SC
Houston, Apollo 11. How about coming up with some roll, pitch, and yaw angles in which to stop this so called orb rate that I'm doing.

CAPCOM
Roger. Stand by.

APOLLO 11 MISSION COMMENTARY    7-19-69     CDT 13:11  -  GET 76:39  -  TAPE 233/2

CAPCOM
We'll have them for you in a minute. Roger.

SC
Okay, and it's time to stop also.

CAPCOM
Yes indeed.

CAPCOM
Apollo 11, this is Houston. Over.

SC
Go ahead, Houston.

CAPCOM
Roger. We show you in the flight plan today in orbital rate until about 79 hours, 10 minutes. Do you have some particular attitude or reason for wanting to go inertial? Over.

SC
No, that's fine. I just wanted to confirm that. Until 79:10 then we'll breeze around here in orbit.

CAPCOM
Roger. And we've got an observation you can make if you have some time up there. There's been some lunar transient events reported in the vicinity of Arastorckus. Over.

SC
Roger. We just went into spacecraft darkness. Until then, why we couldn't see a thing down below us, but now with earthshine, the visibility is oh, pretty fair. I'm looking back behind me I can see the corona from where the sun has just set, and we'll get out the map and see what we can find around Arastorkus.

CAPCOM
Okay, Arastorkus is at angle echo 9 on your ACO chart. It's about 394 miles north of track, however, at your present altitude which is about 167 nautical miles, it ought to be over - that is within view of your horizon, 23 degrees north, 47 west, and take a look and see if you see anything worth noting up there. Over.

SC
Hold a second.

CAPCOM
Roger, out.

PAO
That was Buzz Aldrin discussing the earth shine.

SC
Houston, 11. It might help us a little bit if you could give us a time of crossing 45 west.

CAPCOM
Say again, please 11.

SC
You might give us a time of crossing of 45 west and then we'll know when to start searching for Aristarchus.

CAPCOM
Roger, you'll be crossing 45 west at 77:04:10 or about 40 seconds from now. Over. 30 seconds from now.

SC
Okay.

CAPCOM
Apollo 11, when we lose the S-band we'd like to get OMNI CHARLIE from you and update my last. That 77:04 was the time when Aristarchus should become visible over your horizon. 77:12 is point of closest approach south of it. Over.

SC
Okay, that sounds better because we just went by Copernicus a little bit ago.

CAPCOM
Roger, we show you at about 27 'degrees longitude right now.

SC
Righto.

SC
Houston, when a star sets up here there's no doubt about it. One instant it's there and the next instant it's just completely gone.

CAPCOM
Roger, we copy.

CAPCOM
Apollo 11, this is Houston. We request you use OMNI CHARLIE at this time. Over.

SC
Okay, going to OMNI CHARLIE.

CAPCOM
Roger, out.

SC
Houston, Apollo 11.

CAPCOM
Apollo 11, this is Houston. Go ahead.

SC
Roger. Seems to me we know orbits so precisely and know where the stars are precisely and the time setting of a star or a planet to a very fine degree that this might be a pretty good means of measuring the altitude of the horizon.

CAPCOM
Roger.

SC
Hey, Houston, I'm looking north up toward Aristarchus now, and I can't really tell at that distance whether I am really looking at Aristarchus, but there's an area that is considerably more illuminated than the surrounding area. It just has - seems to have a slight amount of fluorescence to it. As a crater can be seen in the area around the crater is quite bright.

CAPCOM
Roger 11, we copy.

APOLLO 11 MISSION COMMENTARY    7-19-69     CDT 13:46  -  GET 77:14  -  TAPE 235/1

SC
Houston, Apollo 11, looking out the same area now and it does seem to be - reflective ability of earthshine I'm not sure whether it was worked out to be about zero phase, well, at least there 'is one wall of the crater that seems to be more illuminated than the others and that one (garble) lining up with the earth and does seem to put it about at zero phase. That area is definitely lighter than anything else that (garble). I am not sure that I am really identifying any phosphorescence, but that definitely is lighter than anything else.

CAPCOM
11, this is Houston. Can you discern any difference in color of the illumination and is that an inner or outer wall from the crater. Over.

SC
I checked an inner wall in the crater.

SC
No, there doesn't appear to be any color involved in it, Bruce.

CAPCOM
Roger. You said inner wall, would that be the inner edge of the northern surface?

SC
I guess it would be the inner part of the west northwest part. The part that would be more nearly normal if you were looking at it from the earth.

CAPCOM
11, Houston. Have you used the monoculars on this? Over.

SC
Stand by one.

SC
Roger. (Garble) caused me to lose my (garble). It is supposed to be here somewhere but I can't find it.

CAPCOM
11, this is Houston. We're (garble).

SC
Houston, we will give it a try, if we have the opportunity on next - when we are not in the middle of lunch and try to find the monocular.

CAPCOM
Roger. Copied you that time and expect in the next rev you had better be getting ready for LOI, 2, so, let's wind this up and we've got some other things to start you on. Over.

SC
Okay.

PAO
Apollo 11 will be in acquisition for another 20 minutes during its first revolution of the moon.

SC
Okay, you ready to switch to high gain now?

CAPCOM
That's affirmative. 11, Houston. Do you read?

SC
Roger. We read you. It seems to be rather marginal for the high gain.

CAPCOM
Roger. We concur.

SC
Houston, Apollo 11. Could you give us a time of crossing the prime meridian 150 west? Over.

CAPCOM
Roger. Stand by about a half a second, here. Okay, your time of crossing of 150 west meridian will be 775005. Over.

SC
Roger, Houston, we'll try to have it ready.

CAPCOM
This is Houston. We are inquiring if it is your plan to. Over.

SC
It never was our plan to, but it's in the flight plan so I guess we'll do it.

CAPCOM
Houston, roger, out.

11, Houston.

SC
Roger, go ahead.

CAPCOM
For use in connection with the prime meridian crossing you have an orbital period now of 2 hours 8 minutes and 37 seconds. Over.

SC
Thank you.

CAPCOM
Roger, out.

CAPCOM
Apollo 11, this is Houston. A little over 2 minutes to LOS. All your systems parameters and orbit are looking good from the ground. We have AOS on the other side at 78:23:31. Over.

SC
Roger, 78:23:21.

CAPCOM
Roger, that was 31 on the end.

SC
Okay.

PAO
This is Apollo Control. We've had loss of signal from Apollo 11 on its first lunar revolution. We will acquire the spacecraft on the next revolution at 78 hours 23 minutes 31 seconds. The orbital period for Apollo 11's present orbit 2 hours 8 minutes 37 seconds, and as you heard we passed up to the crew information that we would perform the LOI 2 burn using only bank A. The banks are the drive mechanisms for the ball values in the service propulsion system. They open and close these ball valves. The valves allow the fuel and oxidizer to flow into the engine. There are redundant valves and redundant banks, banks A and B. There was apparently - they are driven by nitrogen and that was the reference to the pressure drop there. It was apparently a leak in nitrogen tank B during the LOI 1 burn. This burn was performed with both banks open. The engine can be operated with only bank. It's apparent that the tank leaked only during the burn while the bank was actuated. Pressure has held steady since the end of the burn and the experts are reducing the data and looking at the leak rate, determining whether it was constant throughout the burn, precisely what the situation is. We're showing pressure in tank B of 1960 psi. In tank A 2250 psi. Both of these are well above the red lines of 400 pounds psi.

This is Apollo Control, Houston at 77 hours, 48 minutes now into the flight of Apollo 11. Here in Mission Control Center, Houston we're at the process of changing shifts. Cliff Charlesworth's green team of flight controllers very shortly will be leaving their consoles. Meanwhile Apollo 11 is passing over the far side of the moon out of acquisition. Our last orbital parameter readings on our flight dynamics orbital digital displays indicated an apolune of 168.5 nautical miles, a perilune of 1 - correction, a perilune of 61.2 nautical miles. We're currently planning a change of shift briefing at approximately 2:30 central daylight time or soon thereafter as practicable. The change of shift briefing will include only our flight director, Cliff Charlesworth. It's expected to be of short duration since we will have a TV pass soon after the reacquisition of the spacecraft. At 77 hours, 50 minutes into the flight of Apollo 11, this is Apollo Control, Houston.

This is Apollo Control, Houston at 78 hours, 18 minutes into the flight of Apollo 11. Apollo 11 still passing around the far side of the moon. We are less than 5 minutes now away from time of acquisition on this second revolution for Apollo 11. The station to acquire on this pass will be the Goldstone wing site which will feed the television to Mission Control Center in Houston, and thence to all parts of the country. We would expect to come up with television perhaps some several minutes after acquisition since we must first lock up on the downlink and have the scan converter in full operation. So at 78 hours, 19 minutes continuing to monitor, this is Apollo Control, Houston.

SC
Apollo 11, are you picking up our signals, okay?

CAPCOM
Apollo 11, this is Houston. Confirm. We are reading you loud and clear on voice and we have a good clear TV picture, a little gray crater on the bottom of the picture.

SC
No.

CAPCOM
I guess that is a spot on the tube.

SC
Sorry about that one.

CAPCOM
And if you give us P00 and ACCEPT, we will uplink our state vector and target load to you.

SC
Okay.

SC
Houston, Apollo 11. One of the larger craters on the back side - I noticed a small, dark speck on the outer wall and I put the monocular on it. I was able to see - oh, an area maybe a quarter of a mile in diameter. A really fresh looking dark colored pit and that seems to be in contrast with all the other fresh little craters or holes, that you can perceive on the walls of any of these craters. Around this particular one there seems to be two or three of these - especially the

one that caught my attention. Quite remarkable. Over.

CAPCOM
Roger. Do you have a location on that one?

SC
No, not of (garble). I've got several pictures of it though.

CAPCOM
Roger. We copy.

PAO
That was Buzz Aldrin making a report, a geological report on that site pass.

CAPCOM
We're getting a beautiful picture in down there now, 11. The color's coming in quite clearly and we can see the horizon and the relative blackness of space and without getting into the question of grays and browns, it looks, at least on our monitor a sort of a brownish gray.

SC
(Garble) the way they're describing it. It appears to me as though it made a difference just sitting back in the tunnel and gazing at all windows, it makes a difference which one you're looking out of. For example, the camera right now is looking out the number 5 window and it definitely gives a rosier or tanner tinge, especially when you look straight through it and not at an angle. Over.

CAPCOM
Roger, and for your information we show you at an altitude of about 92 miles above the surface right now .

SC
Okay.

SC
Houston, Apollo 11. Could you observe a difference in the N2 pressures before LOI? It seems to me as though the two were not equal on the (garbled) B tank was a little low on pressure. Over.

SC
I'm flying in an SPS minimum impulse, Houston, and it's rather difficult to keep it on a constant data. The LM wants to wander up and down. I'm not sure if it's in response to mascons or what, but I can get it completely stabiized in data and let it alone and in another couple of minutes it will have developed its own rate.

CAPCOM
This is Houston, Roger.

PAO
That was Mike Collins making that report.

SC
Houston, we'll be moving shortly from the side window to the hatch window, and we'll try and pick up some of the landmarks that we'll be looking at we approach the powered descent. Over.

CAPCOM
11, this is Houston. Roger, and we're through with the uplinks. The computer is yours, you can go to BLOCK and we'll have the information on nitrogen for you shortly. Over.

SC
Roger, copy.

SC
Okay, Houston, several minutes ago I was exactly steady on data and since then I have been moving forward, the LM pointed straight down toward the radius vector and that's been dispite a number of down minimum pitch impulses.

CAPCOM
Roger.

SC
We're over Smyth's Sea right now.

CAPCOM
Roger.

SC
We're about 88 degrees east of it I would estimate.

CAPCOM
We show you about south of the - southwest of the crater Jansky right now.

SC
The Smyth's Sea doesn't look much like a Sea. It's - the area which is devoid of craters of which is not very much is sort of a hilly looking area. It's not like the Mare at all.

CAPCOM
Roger. We copy that about the sea, and it looks like you were just giving us a zero of the crater Neper, the large crater on the left, and Jansky on the right.

PAO
That exchange between Capcom Bruce McCandless and Mike Collins aboard the Apollo 11 spacecraft.

CAPCOM
11, this is Houston. Would you care to comment on some of these craters as we go by?

SC
Roger. We're approaching the approach pass through ignition. This is equivalent to 12 minutes before ignition, and we're at about 83 degrees, I guess. 83 degrees east, Does that correspond to locations you're holding there presently?

CAPCOM
Roger. We're showing your present position as about 77 - 76 degrees east looking back towards the east.

SC
You should be looking back at Manzinus.

CAPCOM
Roger.

PAO
We've now heard from all three Apollo 11 crewmembers during this television pass. The individual talking earlier was Neil Armstrong.

SC
Crater Schubert and Gilbert in the center right now, and that sums it up at about a little over 12 minutes before powered descent. Instead of me looking - as they're looking back at it, we're looking straight down at it.

CAPCOM
Roger. We show you at an altitude now of about 110 miles, and of course, you'll be considerably lower at the initiation of powered descent.

SC
Say, Houston. Look at register 3 on the DSKY data. Update is increasing toward my desired 315 and I'll let the hand controller alone here and I'll bet you it reverses itself.

SC
Roger, 11. We're watching the DSKY now and it's still coming in beautifully on the TV.

Okay, there's - on the right side of the screen at the present time there's a triple crater with a small crater between the first and second, and the one at the bottom of the screen is Schubert Y. (Garble) it does have a central peak at Schubert Y. There's actually several of them. You can observe those, plus the rim craters at the bottom of your screen.

CAPCOM
Roger. We're seeing the central peak quite clearly now.

SC
Okay, we're zooming in now on a crater called Schubert N. Schubert N, very conical inside wall and the bottom of it here looks flat. Look at data on the DSKY it's stabilized and is holding steady now.

Three craters, three horizontal craters, that we now have in the field of view, are immediately underneath the ground track. The right-hand, the largest crater that you see, is through' the (garble).

CAPCOM
Roger, we concur on the identification of this crater.

CAPCOM
- and we show you coming up on landmark ALPHA 1 shortly.

SC
Roger, Mike is having his first look at ALPHA 1 at the present time.

SC
Yeah, it _ is a great bright crater. It is not a large one but an extremely bright one. It looks like a very recent and I would guess impact crater with rays streaming out in all directions which should make ... correction the Foaming Sea easy to see coming up on it now. Crater ... is one of the smaller ones out on the - on the floor of the Foaming Sea.

PAO
We have been some 17 minutes now into this television pass and standing by continuing to monitor.

CAPCOM
Here we can show you over the Sea of Fertility now and we ought to have Langrenus down south of track a few degrees, about 9 degrees south of track.

SC
Now the crater that is in the center of the screen now is Webb. We'll be looking straight down on it at about 6 minutes before power descent. It has a relatively flat bottom to the crater and you can see maybe two or three craters in the bottom of it on the west end wall, the wall that is now nearest the - the camera, near the bottom of the screen we should see a dimple crater there, within the outside and then coming back toward the bottom of the screen into the left, you can see a series of depressions. It is this type of connective craters that give us most interest to discover why they are in the particular pattern that they are in. I'll zoom the camera in and try and give you a closer look at it.

CAPCOM
Roger, we are observing the dimple crater now. The central peak we can see on the other photos

Well, they are not central peaks, they are depressions in the center.

And you will notice on the pitch thruster activity, I've put in oh a dozen interim impulses and pitch down and I am still far from corrective back 315. We are moving the camera over to the right window now to give you well Langrenus. It - its several central peaks and -

CAPCOM
Roger, we got Langrenus in our screen now.

CAPCOM
Okay, 11, this is Houston. We are getting a beautiful picture of Langrenus now with its really conspicious central peak.

SC
The Sea of Fertility doesn't look very fertile to me. I don't know who named it.

SC
Well, it may of been named by - a gentleman whom this crater was named after, Langrenus. Langrenus was a cartographer to the King of Spain and made one of the early reasonably accurate maps of the Moon.

CAPCOM
Roger, that is very interesting -

SC
At least it sounds better for our purposes than the Sea of Crises.

CAPCOM
Amen to that.

CAPCOM
Okay, it looks like you are coming inside now on the camera.

SC
Well, I can't get in behind to see the monitor. I'll bring the focus in but we are going to be looking down past one of the LM quads and one of the antennas almost straight down at the ground track that we will be seeing coming in now. Guess it maybe two or three minutes before power descent.

SC
All right, that should put the LM structure about in focus and I'm going to move it out to Serenity and then expand the field of view.

CAPCOM
Roger, I think we can make them out. The color really enhances the ability to discern features and craters over what we see in real time on our black and white monitor.

SC
Right, at these low sun angles there's no trace of brown, it's now returned to a very gray appearance and, like the acre says, it has a look of plaster paris to it, at this sun angle which is completely lacking in earth angle.

CAPCOM
Roger.

PAO
We're now some 25 minutes into our television pass.

SC
Okay this is very close to ignition point for power descent. Just passing Mount Maryland, a triangular shaped mountain that you see in the center of the screen. At the present time with crater secchi (garbled) on top of the far northern edge of the mountain.

CAPCOM
Roger, we're getting a good view of mount Maryland and Secchi satum.

SC
And now we're looking at what we call boot hill, occurs 20 seconds into the descent.

PAO
Watching this pass with a great deal of interest here in mission control center is Pete Conrad, the commander for the Apollo 12 mission.

SC
On the right edge of the screen crater censorinus P. Now passing the 1 minute point in power descent.

CAPCOM
Roger, and for your information your current altitude is 148 nautical miles above the surface.

SC
It should be. I'm unable to determine altitude at all looking out the window. I couldn't tell whether we were down at 60 or up at 170.

CAPCOM
I bet you could tell if you were down at 50,000 feet.

SC
I wouldn't be surprised.

SC
We're passing some steep ridges here. The edge of the moon craters that were photographed by Apollo 10, and the crew of Apollo 10 was very impressed with the steepness of these ridges when they came over them at about 50 thousand feet.

CAPCOM
Roger, we can observe there also steep even from this altitude. You've got quite a shadow being casted by the sun at these low angles.

SC
The entire surface is getting considerably darker than the surface that we looked at previously when the sun was quite high above us. The crater in the, bright crater

in the center of the screen, the smaller one is censorinus.

CAPCOM
Roger, and we show you low over 1 minute from the terminator at the present time.

SC
How's the brightness of that picture you're receiving? Do you think we ought to open F-stop some as we approach the terminator.

CAPCOM
Yea, the brightness is still doing quite well. You can go ahead and open it up a stop or two. The automatic white level compensation seems to be working beautifully.

SC
There's a good picture of Boot Hill.

CAPCOM
Roger.

SC
3 minutes and 15 seconds into the descent.

CAPCOM
Roger, we're seeing Boot Hill now.

SC
The next crater coming into the bottom of Duke Island there, and to the left, the crater, the largest of the craters, near the center of the picture right now is Maskelyne W. This is a position check during descent at about 3 minutes and 39 seconds, and it's our downrange position check, and cross range position check prior to yawing over face up to acquire the landing radar. Past this point, we would be unable to see the surface below us until getting very near the landing area.

CAPCOM
Roger, I imagine you get a, you'll get a real good look at that tomorrow afternoon.

SC
(garbled) is the one that was referred to in Apollo 10 as Sidewinder.

SC
That's a good name too. Sidewinder, and Diamondback, it looks like a couple of snakes down there in the lake bed.

SC
And we're approaching the terminator now. See the (garbled) has increased and only the sunlit side of these ridges remain illuminated, while the dark sides and the shadow will become completely black.

CAPCOM
11, this is Houston. The picture is getting a little grainy now. You might go ahead and open up the F-stop.

SC
Landing point is just barley in the darkness. That one crater, the upper part of which you see, lower part completely in darkness. The small well defined crater is Moltke, which is about a beam in the landing sight.

CAPCOM
Roger, we can just see it looks like a little less than half of its rim right now.

CAPCOM
And we can make out just barley some features on the surface, maybe from earth shine.

APOLLO 11 MISSION COMMENTARY    7-19-69     CDT 15:20  -  GET 78:48  -  TAPE 242/3

CAPCOM
Are you wide open on the F-stop, at this time.

SC
Now we are. Yea and it looks like we're just about to get the sun comming into the lens so we'll have to move the camera light.

CAPCOM
Roger.

SC
We can't see any earth shine or any surface features at all in earth shine now due to the fact that the LM is very bright and is causing our pupils to contract. It's a very fantastic view to see the terminator as you look along the edge. I think you'll agree that some of these craters that you're seeing in the picture now are really accentuated by the lengthening of the shadows, as compared to the terminator.

CAPCOM
Yes it's a very beautiful and rugged sight we've got on the screen now.

SC
And I think you've got some interesting data on thrustor firing versis pitch angle. It looks like that LM just wants to head down towards the surface is all.

CAPCOM
Roger, I have a comment here that says that's what the LM was built for, I believe.

SC
And as the moon sinks slowly in the west, Apollo 11 bids good day to you.

CAPCOM
Roger, we sort of thought it was the sun setting in the east.

This is Apollo Control, Houston at 79 hours 51 minutes now into the flight of Apollo 11. We are some 20 minutes away, at this time, of ignition for lunar orbit insertion burn number 2. This - the fine tune second burn in the series of two as we have inserted into lunar orbit. For LOI2, the Apollo 11 will be heads down. The burn will be initiated near perilune as the spacecraft passes over the far side of the moon. Retrograde, like LOI1, but unlike Apollo's 8 and 10. The burn will not be targeted to place a spacecraft into a precise circular orbit. Taking what was learned on Apollo 10, this LOI2 burn is designed to take into account predicted perturbations and gradually circularize itself. The numbers that we're looking at for LOI2, that would be time of ignition, 80 hours 11 minutes 36 Seconds, which should change our orbital parameters, giving us an apolune of 65.7 nautical miles and a perilune of 53.7 nautical miles. The Delta-V intended for this burn, 159.2 feet per second. Burn duration anticipated 17 seconds. That's a burn of short duration, but certainly important in that it establishes the proper orbital parameters for the events that lie ahead. As you heard in earlier conversation,

The bank referred to here, which there are two mechanisms that drive the ball valves open and shut, causing fuel and oxidizer to mix for ignition. At the present time in Mission Control Center, the last reference you've heard from our capsule communicator reflects that they, on their own peculiar shift schedule, are having a change of shift. Astronaut Charles Duke has arrived on the scene and we can assume will take over the responsibilities of the conversational flow with the Apollo 11 spacecraft, once we reacquire.

Houston. On your comment about the Maria lapping up to the terrain - mountain of terrain - is that an impression like a lava flow coming in around a prominence, Neil, or more looks like it's sloping up at that point? Over.

SC
It isn't true everywhere, but there's certainly places where there seems to be a slope downward towards the shoreline on the Maria. In other words, from the Maria down to the shoreline is a downward slope indicating that it might be a lava flow.

Apollo Control, Houston. At 81 hours 5 minutes into the flight. Still a period of relative quiet. Our ground readings indicate that the Apollo 11 spacecraft has completed its program of 52, that's to align the inertial platform. Indications from the ground are that it - this activity went very well. And at 81 hours 6 minutes continuing to monitor, this is Apollo Control, Houston.

PAO
This is Apollo Control, Houston, at 81 hours 15 minutes. It's been an extremely quiet pass. No doubt, the Apollo 11 crew, quite busy at this time. We expect, at the time entry is made into the lunar module, Apollo 11, as a matter of fact, will be out of acquisition, traversing over the far side of the moon. At the present time, we read an altitude, current altitude, reading of 56.7 nautical miles. Our ground displays indicate an apolune of 65.4, a perilune of 53.8 and spacecraft velocity of 5,364 feet per second. Continuing to monitor, this is Apollo Control, Houston, at 81 hours 16 minutes into the flight.

CAPCOM
Roger. Thank you much, Neil. We'll be standing by.

PAO
This is Apollo Control, Houston at 81 hours 24 minutes now into the flight. The silence of conversation between Mission Control Center, Houston and the crew has broken there moments ago. Charlie Duke called up Apollo 11 and spoke with Neil Armstrong, who indicated that the hatch was out and the probe and drogue removed and they were about ready to open the lunar module hatch. Our current altitude shows 54.7 nautical miles, apolune, 65.4, perilune, 53.8. Interestingly enough, the part of the LM activation which we will follow up most closely will be at time of reacquisition following our pass over the far side of the moon. This will be on the front side. It will afford us an opportunity for a communications check with the lunar module and there will be a transfer to LM power. At 81 hours 25 minutes, this is Apollo Control, Houston.

Apollo Control, Houston. We're now within 2 minutes from time of predicted acquisition of the Apollo 11 spacecraft. As we make this pass - near side pass, on the fourth revolution, it will be the first time that we have transferred during this mission to lunar module pilot power, and a communications check will be performed on the lunar module. We should be hearing such things as long counts being given from the spacecraft. Additionally, a new display - the lunar landing site display is now up for the first time in Mission Control Center this flight. It's essentially a blowup for the landing sites 1 and 2. We expect it to stay up through the time of lunar landing. Meanwhile a Mission Control Center Flight Director, Milt Windler, beginning to discuss with members of his Flight Control team items that might be expected after we acquire.

Apollo 11 has passed out of range with the ground, traversing now over the far side of the Moon. During this pass, we had an extremely successful communications checkout with the lunar module using its code name for the first time. Its code name of the Eagle. Buzz Aldrin performed the counting tasks in concert with Charlie Duke, the capsule communicator here on the ground, and at times Buzz's - Buzz's voice, we noted considerable enthusiasm for the way things are going, and at times Charlie Duke shared that enthusiasm and its maiden checkout in communications, the lunar module Eagle, looked good.

Meanwhile in Mission Control Center, Astronaut Owen Garriott has now replaced Charlie Duke as our Capsule Communicator. We expect that some final advisories will be passed to the Apollo 11 crew, and final report says such as crew status will be received from Neil Armstrong, Mike Collins, and Buzz Aldrin prior to the start of their sleep period. A little over - we're a little over a minute away now from scheduled time of acquisition. We'll continue to keep the line up and continue to monitor. This is Apollo Control, Houston.

This is Apollo Control, Houston. Owen Garriott getting ready to place a call.

CAPCOM
Over.

SC
Houston, Apollo 11.

CAPCOM
11, Houston. Roger. Reading you fine, and it looks like the automatic REACT went very well just because you came around the LM. We have several small items to discuss with you here just before you go to sleep. Over.

SC
Go ahead. Over.

CAPCOM
Okay, 11. First of all, on our LM systems checks. Everything went fine. I would like to remind you though tomorrow you may see an asc>ent pressure light when you activate the MC and W. There should be no problem, however. You did note that the AP - OP tank pressure was only reading 111 psi, which is normal at this point, but the below the level which will trigger your light due to the helium which has been disolved into the propellant. Over.

SC
Roger. Understand that. Thank you.

CAPCOM
Roger. And next item, the supercritical helium rise rate is nominal, and you also had that question for us about your thruster activity during the P22 on the last REV. Believe we understand that now, and you reported that your pitch was in ACCEL COMMAND and your yaw and roll were in REG COMMAND. You were firing your pitch thrusters that will couple REG into your yaw and roll axes, and the - you were at that time holding only half a degree deadband and coupling REG's into yaw and roll produced the extra firings about the yaw and roll axes. Over.

SC
Yes, that may be true. It's very peculiar coupling in that it waits longer than you would think and its

APOLLO 11 MISSION COMMENTARY    7-19-69     CDT 20:59  -  GET 84:28  -  TAPE 262/2

SC
reaction is greater than you would think. We were getting yaw rates of around four tenths of a degree per second per panel.

CAPCOM
Roger, Mike. We did play the data back and that's the way it looked upon analysis of the chart recordings back here. Over.

SC
Okay. Fine.

CAPCOM
They've also looked at the results of your landmark tracking. The marks all apparently were very good and we've got a full page of data here relative to the altitudes of the various track locations, which I won't read up to you, but I did want to let you know that the marks apparently went very well. I also have your consumables budget, particularly your RCS propellant quantities. They're Deltas from nominal if you should want them. Your work quad is quad Charlie, which is 9 percent low. I'll not read up the others unless you want them. Over.

SC
Okay, I got the O2 fuel cell purge. You want them now?

CAPCOM
I'll have to stand by just a moment.

SC
Okay. And then the other one is we're still charging battery A.

CAPCOM
11, Houston. We would like to delay the fuel cell purge until the back side of the moon, and you go ahead and - should terminate your battery charge at this time. Over.

SC
Okay; understand, I knew we had another O2 and H2 purge coming up in the morning, I wasn't sure whether you wanted to go through with this one or not. I'll wait until the next side and then do it.

CAPCOM
That's fine, Buzz.

SC
Terminate battery charging now.

CAPCOM
That's right and one other systems item here - in order to balance your cryo tanks, would you get your O2 and tank 1 and your H2 tank 2 heaters off. Over.

SC
Okay, I have O2 tank heater I off, and H2 tank heater 2 off.

CAPCOM
That's right, Mike, and we believe you have your quad Bravo and quad Charlie turned off in your DAP at this time, and a 5 degree deadband. We'd prefer a 10 degree deadband for your sleep period overnight here. Over.

SC
Okay.

CAPCOM
One Other item relative to a malfunction procedure. It's unlikely that you'll have to worry about this tomorrow, but in your malfunction list under docking on page Fll-9 there is a malfunction procedure for a high O2 flow rate at the top - under tunnel at the top of page 11-9. We would like to have you not use that malfunction procedure should you encounter the high O2 flow rate, and instead

SC
Understand and note has been made in my checklist.

CAPCOM

PAO
This is Apollo Control, Houston 84 hours, 48 minutes now into the flight. We're receiving noisy data at this time. We've requested Apollo 11 to give us a manual relock. Standing by at 84 hours, 49 minutes this is Apollo Control, Houston.

CAPCOM
Apollo 11, Houston. We're still unable to pick you up on the high gain antenna. We request you go to MANUAL from wide beam width. The Pitch and Yaw angles in your checklist. You should be able to find us there. Over.

SC
Houston, Apollo 11. How do you read now?

CAPCOM
11, Houston. Loud and clear this time. OMNI.

SC
Loud and clear. You faded out on your other transmissions. Over.

CAPCOM
Roger. Are you in wide-beam now?

SC
Negative, but I've got you locked back on again REACQING now.

CAPCOM
Roger. That's all we want. We want to stay in narrow and we're a little puzzled about why we lost you here a few minutes ago. Do you have any ideas?

SC
Sure don't. We're showing the background - 15 degrees for the pitch and about 270. That ought to be good and clear.

CAPCOM
We concur that. We still don't have any good ideas on why we were lost.

CAPCOM
11, Houston. Would you confirm that we did acquire automatically when you came around the LM for this passage. Over.

SC
That's confirmed.

CAPCOM
Thank you.

This is Apollo Control, Houston 84 hours, 56 minutes are now in the flight of Apollo 11. Our current apolune 65.1 nautical miles, current perilune 54.3 nautical miles. After receiving some noisy signal, Apollo 11 has locked back on in fine form. That was Buzz Aldrin speaking with Owen Garriott here in the Mission Control Center. I expect we will take a second look at why we had to lock on manually. As we receive any updates on this, we'll pass them along. We now read 84 hours, 57 minutes and this is Apollo Control, Houston.

As was pointed out, quad, RCS quad Charlie is now disabled following that conversational exchange between Owen Garriott and Buzz Aldrin. Buzz, the lunar module pilot apparently, quite obviously still awake. 85 hours 7 minutes now into the flight of Apollo 11 now continuing to monitor, this is Apollo Control, Houston.

CAPCOM
Apollo 11, Houston, over.

SC
Go ahead Houston.

CAPCOM
Eleven, Houston. We're going to try to check out this ability to automatically reacquire on the S-band and what we want to do is to secure our uplink carrier for about 30 seconds, then we will turn it back on and see if the spacecraft equipment will automatically reacquire. So if you do not get a call from us within about 3 minutes, that means we have not been able to reacquire and request your assistance on a manual acquisition, over.

SC
Okay, we understand.

CAPCOM
Eleven Houston, we also would appreciate if you will note the angles that the antenna tracks through in its attempt to reacquire, over.

SC
Roger, we'll do that.

APOLLO 11 MISSION COMMENTARY    7-19-69     CDT 21:44  -  GET 85:13  -  TAPE 266/1

CAPCOM
11, Houston. It looks like we're locked back up again with no delay. How does it look on board? Over.

SC
Roger. The signal strength dropped very rapidly to zero and the pitch and yaw, in about 3 seconds, moved towards 40 degrees pitch and 240 degrees yaw. Right now, we're setting on about 15 degrees pitch and roll about 265 degrees yaw. So they didn't move very far, oh, about 30 degrees apiece and then they picked right back on up again. Over.

CAPCOM
Roger. Some of the luckiest people in the background there. We copied your pitch and yaw angles.

CAPCOM
11, Houston. You give us the location of your pitch and yaw location of your position indicators. Over.

SC
Roger. They're in the same position as the antenna right now, about 15 degrees pitch and - No, wait a minute. I got them - got it at about 75 instead of 265.

CAPCOM
Okay, thank you.

CAPCOM
11, Houston. We'd like to try the same procedure once more. We'll leave the carrier a little longer and be back up for a call within 4 minutes. Over.

SC
Okay.

PAO
This is Apollo Control, Houston. At 85 hours 17 minutes now into the flight of Apollo 11. What you heard in the conversation between Owen Garriott and Buzz Aldrin was following a communications check in which we secured the uplink carrier for some 30 seconds and waited to give it a period of time of approximately 3 minutes, to see if the spacecraft would reacquire. We appeared to reacquire in fine form on this first test. We will repeat it - this test a second time, delaying approximately 4 minutes before we place a call to Apollo 11. At 85 hours 17 minutes, we currently read an altitude - spacecraft altitude of 56.1 nautical miles. Present velocity shows 5,367 feet per second. At apolune 65 nautical miles, perilune 54.4 nautical miles. Present weight in orbit remains a static 70,502 pounds. Present time in orbit as shown on our displays, 1 hour 58 minute 40 seconds. This is Apollo Control, Houston.

CAPCOM
11, Houston. We're locked back up again. Can you give us a report on how the antenna behaves?

SC
Roger. It was essentially identical as before. The pitch went to 45, 40 to 45 and then the yaw went to about 255, 245 to 255 and then it rather quickly locked up at 15 degrees pitch and 270 yaw. Over.

APOLLO 11 MISSION COMMENTARY    7-19-69     CDT 21:44  -  GET 85:13  -  TAPE 266/2

CAPCOM
11, Houston. Roger. Your angles of 45 and 255. Do I understand that as soon as the carrier dropped, it went to these angles, or did it only go to these angles after the uplink carrier was reenabled and the antenna began to reacquire. Over.

SC
No. As soon as the carrier dropped off, why it drifted over into those angles and stayed there. Then when it came back up again, why it hunted around for a while, but it didn't get any further off, gradually brought it on in to the angles where it is right now, and they the signal strength, would take several jumps as evidentally it goes from wide to medium to narrow.

CAPCOM
11, Houston. I understand, and on another subject, request you zero your optics for the night. Over.

SC
Roger. Zero.

SC
Somebody will be up.

CAPCOM
Roger. The thing that we are still puzzling on is the antenna and if - as long as there will be somebody up, why we would like to have somebody check the automatic REACQ on the next AOS.

SC
Okay, we'll do that. We haven't chlorinated the water yet and we haven't changed the lithium hydroxide. We're still finishing up dinner.

CAPCOM
Rog, Mike thank you.

PAO
This is Apollo Control, Houston, at 85 hours 29 minutes now into the flight. That was Mike Collins reporting to the capsule communicator Owen Garriott that the Apollo 11 crew completing dinner at this time. And earlier perhaps if you listened to the air/ground, you heard some music in the background, soft music which would indicate that the this was being played in concert with their evening meal. When we reacquire, we expect one of the three crew members to still be, at least one to be still awake as we run a further check on our spacecraft antenna. At 85 hours 30 minutes into the flight of Apollo 11, this is Apollo Control, Houston.

We're just finishing up our fuel cell purge hydrogen on number 3 is the last to go off. They'll be coming off just in a second.

CAPCOM
Roger, 11. Apollo 11, Houston. We believe we've tracked down the reacquisition problem we had on the previous rev. It looks like it was a receiver power supply here on the ground and no problems in the spacecraft at all. Over.

This is Apollo Control, Houston, 86 hours, 33 minutes. You heard that last exchange. The Mission Control Center has isolated our earlier loss of lock on with the S-Band antenna to a faulty power supply to Goldstone which in turn introduced noisy data causing a ground based receiver to go out of lock. This power supply, a 24 volt one, has already been replaced at Goldstone. In summary, the spacecraft looks good and the difficulty was caused here on the ground.

This is Apollo Control. 94 hours, 21 minutes ground elapse time. Should have acquisition of signal as Apollo 11 comes around on the front side of the moon on the 10th revolution. AOS is confirmed. We'll stand by Capcom's call to the crew. We have data coming in now. After having breakfast and getting all squared away after the night's rest period, the crew will have a rather busy day including the first man landing on the moon. Some of the preliminary time's being generated now for maneuvers of the day - will include separation at - a separation burn at 100 hours, 39 minutes, 50 seconds. Here goes the call.

This is Apollo Control following the separation burn at the time of 100 hours, 39 minutes, 50 seconds. The descent orbit insertion burn is now scheduled at 101 hours, 36 minutes, 13.5 seconds. Our descent initiation at 102 hours, 32 minutes, 05.1 seconds. We'll stay up live on the air-ground loop, and continue to monitor any further conversation between spacecraft communicator, Ron Evans, here in mission control and the crew of Apollo 11, which at this time is likely in the middle of their breakfast period.

PAO
This is Apollo Control still standing by as the Apollo 11 - about a third of the way through the front side pass on revolution number 10. Still in the midst of their breakfast period. Various console positions are preparing numbers for maneuver times, attitudes, and so on for the day's activities to pass to spacecraft communicator who in turn will pass them up to the crew. Probably during this pass - members of the white team of flight controllers headed up by Eugene Kranz are drifting into the control room now to relieve the night watch - black team headed by Glynn Lunney. Glynn Lunney will hold a brief change of shift press conference in the Apollo news center in MSC after the handover is complete. We'll continue to monitor the air-ground circuit for any further transmissions from Apollo 11.

During that pass, Armstrong and Aldrin in the lunar module begin checking out activating the lunar module, and they appeared to finish about 30 minutes ahead of the scheduled time in the flight plans. They began early and have maintained the pace. Both spacecraft looking very good at this time. Everything progressing very smoothly. On the next revolution, revolution 12, the crew will continue activation and checkout of lunar module systems. The following revolution, revolution 13, they will undock from the command and service module. At 97 hours, 33 minutes, this is Apollo Control.

This is Apollo Control at 98 hours, 16 minutes. We are now less than 2 minutes from reacquiring the spacecraft in its 12th revolution of the moon. At this time Armstrong and Aldrin should be completing pressure checks on their spacesuits. Coming up in this revolution, they will be running checks on the guidance platform of their LM guidance system. They will also be running checks on the reaction control system thrusters and their descent propulsion system, as well as the rendezvous radar. We will also be giving them the GO/NO GO for undocking in the following revolution. The checkout and activation up to this point has been moving along very smoothly. All systems performing well and we were ahead of the flight plan at the end of the last revolution. We will stand by now to reacquire the spacecraft. The LM and CSM are still docked and Armstrong and Aldrin within the LM. That will be their home for the next 30 hours or so. Now about 45 seconds from reacquiring. We are now about 15 seconds from reacquisition of Apollo 11. Spacecraft currently in an orbit with an apocynthion of 63 and one-half nautical miles and pericynthian of 55.9, as we are continuing to see the apocynthion drop and pericynthian raise as the orbit becomes more and more circular. We should have acquisition of signals shortly. We will have some noise on the circuits until the LM ,steerable and the CSM high gain antennas are brought into play. CAPCOM Charlie Duke putting in a call to the crew. We'll continue to stand by.

PAO
Charlie Duke asking the crew to verify in the LM that they are on their forward OMNI antenna. We are still awaiting lockup and a stronger signal. We will continue to have noice on the circuit until we get a stronger signal. We do have telemetry data from the spacecraft at this time.

to take marks on a landmark near the prime landing site. This information will be received here in Mission Control and will be used to update the Ground's knowledge of where the spacecraft is, and in turn that information will assist them in setting the precise time for the powered descent. Once the orbital navigation is completed we'll be able to get a high gain antenna and LM steerable antenna lock and we should see some improvement in the communications.

PAO
This is Apollo Control. We've had loss of signal now, and the spacecraft Eagle has been given a GO for descent orbit insertion. That maneuver to occur in 7 minutes 40 seconds. Out of contact - out of radio contact, the DOI maneuver scheduled to come at 101 hours, 36 minutes, 14 seconds, and it will be a 76.4 foot per second burn. The burn duration 29.8 seconds, and the resulting orbit for the LM will be 57.2 by 8.5 nautical miles. When next we acquire the lunar module, it should be at an altitude of about 18 nautical miles on its way down to a low point of about 50,000 feet from where the powered descent to the lunar surface will begin. As the spacecraft went around the corner, all systems on both vehicles looked very good. Everything is GO here in mission control and aboard the spacecraft for the descent orbit insertion to occur in 6 minutes, 38 seconds. This is Apollo Control, Houston, at 101 hours 29 minutes.

PAO
This is Apollo Control at lOl hours, 35 minutes. We're. now. less than one minute from the scheduled time for the descent orbit insertion maneuver performed by the lunar module on the backside of the moon. Of course, we don't have radio contact with the spacecraft. In mission control here normally maneuvers of that sort would be monitored on plot boards in front, and we have the boards set up there for the powered descent. To occur about 1/2 rev from now over landing site 1. Flight controllers standing around in little groups. Not much that we can do at this point until reacquiring spacecraft. We're now 20 minutes - or 20 seconds rather from ignition on the descent orbit insertion. It will be a 29.8 second burn of the 9800-pound thrust descent propulsion system. We should be burning at this time. The result of this maneuver will be to put the spacecraft into an orbit 57.2 by 8.5 nautical miles, and it would remain in that orbit until powered descent.

PAO
We should have a cut off by this time. That should have completed descent orbit insertion maneuver. We would expect to reacquire the command module first. Command module acquisition time is 102 hours, 14 minutes, 38 seconds. That will be just about 2 minutes prior to the time that we will have reacquired the lunar module. The LM acquisition time is 102 hours, 16 minutes, 25 secomds. That is about 37 minutes, 20 seconds from now on the CSM at about a little less than 2 minutes longer than that for the LM. At 101 hours, 37 minutes, this is Apollo Control, Houston.

PAO
This is Apollo Control at 101 hours, 54 minutes. We're now about 20 minutes, 45 seconds from reacquiring the command module on the 14th revolution. The time until the ignition for the power descent is 38 minutes, 55 seconds. Here in mission control, people still standing and waiting. I believe back in the viewing room, we probably have one of the largest assemblages of space officials that we've ever seen in one place. Included among the viewers are Dr. Thomas Paine, NASA Administrator, Jim Elms, Director of the Electronic Research Center at Cambridge, Dr. Abe Silverstein, Director of NASA's Lewis Research Center, Rocco Petrone, Director of Launch Operations at Kennedy Space Center is there. From Marshall Space Center, we have Dr. Wernher von Braun, the Director, and his Deputy, Dr. Eberhard Rees. Also a large number of Astronauts including Tom Stafford, Gene Cernan, Jim McDivitt, and John Glenn. We also see Dr. Kurt Debus, Director of the Kennedy Space Center, Dr. Edgar Cortright, Director of the Langley Research Center. Dr. S. Draper, Director of the Massachusetts Institute of Technology Instrumentations Laboratory is also in the viewing room. Here in the control room proper down on the floor a number of Astronauts including Pete Conrad, Fred Haise, Jim Lovell, and Bill Anders, and Donald K. Slayton, Director of Flight Crew Operations at the Manned Spacecraft Center. Sitting beside us in the back row of consoles here is Dr. Robert Gilruth, Director of the Manned Spacecraft Center. Further down on the line is General Sam Phillips, Director of the Apollo Program. Also Chris Kraft is here, Director of Flight Operations at the Manned Spacecraft Center, and George Low of the Apollo Spacecraft Program Manager. We also see in the back viewing room, Secretary of the Air Force, Seamans, and many others who I'm sure we can't see through the glass. We're now 18 minutes, 10 seconds until reacquisition of the spacecraft. Ignition for the power descent to the lunar surface is 36 minutes, 30 seconds away. At 101 hours, 57 minutes, this is Apollo Control, Houston.

This is Apollo Control at 102 hours 12 minutes into the flight of Apollo 11. We're now 2 minutes 53 seconds from reacquring the spacecraft, 21 minutes 23 seconds from the beginning of the powered descent to the lunar surface. It's grown quite quiet here in Mission Control. A few moments ago Flight Director Gene Kranz requested that everyone sit down, get prepared for events that are coming, and closed with a remark "Good luck to all of you". Here on the front of our display boards we have a number of big plot boards which will be used to keep track of the burn progress. Along the more important of those is one which will show the performance on onboard guidance systems, both the primary and the back up guidance system and compare the guidance systems with the Manned Space Flight Network tracking. These displays, by the time this is all over, will look a great deal like a combination Christmas tree and Fourth of July. We're now 1 minute 39 seconds from reacquiring the command module, Columbia. Acquisition of the lunar module will come a little less than 2 minutes after that. At the time we acquire the LM it should be at an altitude of about 18 nautical miles descending toward the 50,000 foot pericynthion from which point the powered descent to the lunar surface will be initiated. If for any reason the crew does not like the way things look as they are coming across the pericynthion, simply by not initiating the maneuver they will remain in a safe orbit of 60 miles by 50,000 feet, and if they desired they would be able to attempt the powered descent on the following revolution at a ground elapsed time of about 104 hours 26 minutes. We're now coming up on 30 seconds to acquisition of the command module and we'll stand by for that event.

We don't expect much in the way of a visual description of the landing area from the crew until after we get through these critical stay, no stay periods and have gotten the status to remain on the lunar surface for at least 1 command and service module revolution. All spacecraft systems continue to look good to us here on the ground.

EAGLE
Tranquility base, Houston, we recommend you exit PI2, over.

EAGLE
Houston, that may have seemed like a very long final phase. The auto targeting was taking us right into a football field, football field sized crater, with a large number of big boulders and rocks for about 1 or 2 crater diameters around us, and it required a (garbled) on the 366 and flying manually over the rock field to find a reasonably good area.

We'll get to the details of what's around here, but it looks like a collection of just about every variety of shapes, angularities, granularities, every variety of rock you could find. The colors vary pretty much depending on how you're looking relative to the 0 phase point. There doesn't appear to be too much of a general color at all, however it looks as though some of the rocks and boulders, of which there are quite a few in the near area, it looks as though there going to have some interesting colors to them, over.

The Czar has said that we wouldn't be able to tell precisely where we are the winners today. We were a little busy, worrying about program alarms and things like that. Part of the descent where we would normally be picking out our landing spot and aside from a good look at several of the craters we seen over in the final descent, I haven't been able to pick out the things on the horizons. I haven't had the reference as yet.

CAPCOM
Roger Tranquility. No sweat. We'll figure it out. Over.

You might be interested to know that I don't think I noticed any difficulty at all in adapting to 1/6g, At least, immediately natural to move in in this environment.

Neil Armstrong reporting there. No difficulty adapting to the one-sixth gravity of the moon.

EAGLE
Window is a relatively level plain crated with a fairly large number of craters of the five to fifty foot radi and from ridges small 20, 30 feet high I would guess and literally thousands of little one and two foot craters around the area. We see some angular blocks out several hundred feet in front of us that are probably 2 feet in size and have angular edges. There is a hill in view, just about on the ground track ahead of us, difficult to estimate but might be a half a mile or a mile.

CAPCOM
Roger Tranquility. We copy. Over.

COLUMBIA
Sounds like it looks a lot better now than it did yesterday at that very low sun angle. It looked rough as a cob then.

It was really rough Mike over the targeted landing area but it was extremely rough cratered and large numbers of rocks that were probably some, many larger than five or ten feet in size.

I'd say the color or the, the local surface is very comparable to what we observed from orbit at this sun angle, about 10 degrees sun angle, or that nature, it's pretty much without color. It's gray and it's a very white, chalky gray, as you look into the zero phase line and it's considerably darker gray, more like ash ashen gray as you look up 90 degrees to the sun. The, some of the surface rocks in close here that have been fractured or disturbed by the rocket engine are coated with this light gray on the outside but when they've been broken they display a dark, very dark gray interior and it looks like it could be country basalt.

From the surface, we could not see any stars out the window, but I had my overhead patch. I'm looking at the earth. It's big and bright and beautiful. Buzz is going to give a try at seeing some stars through the optics.

CAPCOM
Roger, tranquility. We understand. It must be a beautiful sight. Over.

PAO
We would like to point out that the fuel pressure problem that had been called to the attention of the crew, is in the descent system and it is probably the downstream of the tanks where a small amount of fluid has been trapped in a line and we don't expect it to cause any problem. The line should be able to take far more pressure than the fluid would exert. In the event that there was an overpressurization, we would expect that the line would spring a small leak, the pressure would drop rapidly. Again, we point out that we do not see this as a significant problem.

CAPCOM
Columbia, Houston. 2 minutes to LOS. You're looking great going over the hill. Over.

COLUMBIA
Okay, thank you. My glad to hear the system's looking good. You have a suggested attitude for me. This one here seems'alright.

Okay, thank you.

PAO
This is Apollo Control. We've had Loss of Signal now from the command module and of course, we'll maintain constant communications with the lunar module on the lunar surface. We have some heart rates for Nell Armstrong during that power descent to the lunar surface. At the time the burn was initiated, Armstrong's heart rate was 110. At touchdown on the lunar surface, he had a heart rate of 156 beats her minute, and the flight surgeon reports that his heart rate is now in the 90's. We do not have biomedical on Buzz Aldrin.

PAO
This is Apollo Control at 103 hours 32 minutes. We have an update on that touchdown time on the lunar surface. This still is not the final, official time which we will get from readout of data, but the refined time is 102 hours 45 minutes 40 seconds, which would have been 12 minutes 36 seconds after initiating the powered descent. That was 102 hours 45 minutes 40 seconds for touchdown and a total time of powered descent 12 minutes 36 seconds, and we would expect then those numbers to change perhaps a little when we get final data readouts.

We also have some updated information on the landing point. It appears that the spacecraft, Eagle, touched down at 799 degrees north, or just about on the lunar equator. And 23.46 degrees longitude, which would have put it about 4 miles from the targeted landing point downrange. We're now 54 minutes - rather 27 minutes from reacquisition of the command module, and of course, we're in constant contact with the lunar module on the surface.

This is Apollo Control, Houston at 104 hours 44 minutes. You heard that last exchange and there is a very strong indication we might have an early EVA with the hatch opend perhaps at 8:00 Houston time. One other item of significance that this the pressure rise in - depth descent propellant line downstage of the tanks has relieved all aspects of the mission, looking very good at this time. At 104 hours 45 minutes now into the flight of Apollo 11, this is Apollo Control, Houston.

This is Apollo Control, Houston at 105 hours now into the flight of Apollo 11. We expect a - our - our capsule communicator Owen Garriott to pass along data to spacecraft Columbia, momentarily. We're standing by for that. Meanwhile, I think we should discuss a little further the projected EVA. Our current plan is to have crewmembers above the Eagle to eat and relax for a little while prior to starting EVA preps. We won't know with certainity or have a reasonable time hack until about an hour before the scheduled event. Right it looks like it could occur at 8:00 Houston time. We have conversation going now with the spacecraft. We'll pick that up.

We won't know for sure about the time, with reasonable certainty until about an hour before the event. Meanwhile, as we'll soon be progressing toward man's first step on the lunar surface, we have an interesting phenomena here in the mission control center, Houston. Something we've never seen before. Our visual of the lunar module, our visual display now standing still. Our velocity digitals for Tranquility Base now reading zero. Reverting, if we could, to the terminology of an earlier form of transportion, the railroad. What we're witnessing now, is man's very first trip into space with a station stop along the route.

CAPCOM
Columbia, this is Houston. We request that you perform another P22. We'd like you to let the auto optics take care of the tracking and devote your energies to trying to pick out the LM on the Lunar surface. If you can find the LM, of course. We're looking for marks on it, but tracking of geographical features doesn't do us all that much good, over.

Okay, I'll do it. And on the ESCS system, we're having a problem with it. It seems to have gone away without any changing of J52 sensors or anything like that my glycol evaporator outlet temp is up above 50 now and it's quite comfortable in the cockpit so we'll talk more about that one later.

Okay, I was looking in the wrong place last time. Auto optics were not pointing at the coordinates you gave me.

CAPCOM
Roger.

CAPCOM
Columbia, this is Houston, over.

COLUMBIA
Go ahead.

CAPCOM
On your next pass Columbia rather than performing a P22 as scheduled, we would like you to look into the center of the coordinates we gave you which is our best analysis based on MAP physics trajectory and we also have another set of coordinates that we would like you to search in the vicinity of. This last one being based on an interpretation of the geological features that were seen by the crew on the way down. The coordinates of this second site are MIKE .7 and 8.0. I say again. MIKE .7 and 8.0. Over.

COLUMBIA
Roger, copy. MIKE .7 and 8.0. The only thing is my best tool for looking is the sextant and if I bring the sextant up, I might as well let P22 go at the same time or don't you think -

CAPCOM
Roger, if you want to go that way, crank it up and then you can drive it around and look where you want, over.

COLUMBIA
Okay.

CAPCOM
And if you can find the LM then by all means track it or make a note of where is was and we can track it on the next rev. If you are ready we have a RFSMMAT update that we can pass up to you at this time if you will give us P00 and accept, over.

COLUMBIA
Okay, P00 and accept you got and this is an updated landing site RSFMMAT. We still believe that a plane change is not required. Is that affirmative?

CAPCOM
That's affirmative, Columbia.

On our next pass I'd appreciate the S-band relay mode, over.

CAPCOM
Roger, we're working on that. There haven't been any transmissions from Tranquility Base since we last talked to you. We can not give you a full S-band relay without being assured of high gain antenna. We're working on the partial relay for you, over.

COLUMBIA
Okay, understand, Bruce. Thank you very much.

CAPCOM
Columbia, this is Houston. Approximately 2 minutes to LOS all your systems are looking good from down here, over.

CAPCOM
Roger, Columbia, doing this pass on the front side it looked okay to us.

COLUMBIA
Okay, thank you.

PAO
This is Apollo Control at 107 hours 23 minutes, and we've had loss of signal on Columbia. The clock here in the control center counting down to depressurization time on Eagle shows we're 36 minutes 39 seconds away from that event. We believe the crew is pretty well on the time line in EVA preperations. We will next acquire Columbia at 108 hours 9 minutes 6 seconds. Columbia's closest approach to Eagle on this next revolution will come at 108 hours 35 minutes 28 seconds when it should be 3 miles south of the track.

We'll have to wait until Eagles crew, Neil Armstrong, and Buzz Aldrin, give us some more information about how they're coming along in the preperations for the EVA. Indications are now that they are running on the order of 30 minutes behind the nominal time, preparations line. Maybe a little bit longer.

I'm at the foot of the ladder. The LM foot pads are only depressed in the surface about 1 or 2 inches. Although the surface appears to be very, very fine grained, as you get close to it. It's almost like a powder. Now and then, it's very fine.

There seems to be no difficulty in moving around as we suspected. It's even perhaps easier than the simulations at 1/6g that we performed in the simulations on the ground. It's actually no trouble to walk around. The descent engine did not leave a crater of any size. There's about 1 foot clearance on the ground. We're essentially on a very level place here. I can see some evidence of rays emanating from the descent engine, but very insignificant amount. Okay, Buzz, we're ready to bring down the camera.

I'm all ready. I think it's been all squared away and in good shape. Okay? Okay, you'll have to pay out all the LEC. It looks like it's coming out nice and evenly.

Go ahead Mr. President, this is Houston. Out.

PRES NIXON
Neil and Buzz, I am talking to you by telephone from the Oval Room at the White House. And this certainly has to be the most historic telephone call ever made. I just can't tell you how proud we all are of what you ... for every American, this has to be the proudest day of our lives. And for people all over the world, I am sure they, too, join with Americans, in recognizing what a feat this is. Because of what you have done, the heavens have become a part of man's world. And as you talk to us from the Sea of Tranquility, it inspires us to double our efforts to bring peace and tranquility to earth. For one priceless moment, in the whole history of man, all the people on this earth are truly one. One in their pride in what you have done. And one in our prayers, that you will return safely to earth.

ARMSTRONG
Thank you, Mr. President. It's a great honor and privlege for us to be here representing not only the United States but men of peace of all nations. And with interest and a curiosity and a vision for the future. It's an honor for us to be able to participate here today.

PRES NIXON
And thank you very much and I look forward - all of us look forward to seeing you on the Hornet on Thursday.

ARMSTRONG
Thank you.

Houston, it's very interesting to note that when I kick my foot (cut out) - there's no atmosphere here, and this gravity (cut out) - they seem to leave, and both of them have about the same angle of departure and velocity. From where I stand, a large portion of them will know by impact that they're a good two thousand. Several - the percentage is, of course, is ruled by impact. Different reasons (cut out) - it's highly dependent upon depth, the initial trajectory upward, where most of the - already the particles are found especially strange.

In general, time spent in the shadow doesn't seem to have any (cut out) effects. (Cut out) inside the suit. There is a difference, of course, in the coming radiation and the helmet. So I think there's a tendancy to feel a little poor in the data (Garble).

ALDRIN
I can understand that.

PAO
Neil's been on the surface now slightly over an hour and 20 minutes.

ARMSTRONG
I don't note any abnormalities in the LM. The pods seem to be in good shape. The primary and secondary struts are in good shape. Antennas are all atrace. There's no evidence of problem underneath the LM due to engine fault or drainage of any kind.

CAPCOM
Roger. Out.

ALDRIN
It's very surprising, the surprising lack of penetration of all four of the foot pads. I'd say if we had gone farther below the surface, they would have penetrated maybe another three inches. Wouldn't you say, Neil?

ARMSTRONG
At the most, yes. But, I could tell they settled even less than that.

ARMSTRONG
(garbled)

ALDRIN
I get a picture of the XY strut taken from near the descent stage, and I think we'll be able to see better what the facts are. Seem to be quite minimum.

ALDRIN
There's one picture taken in the right rear of the spacecraft looking at the skirts of the descent stage. Quite darkening of the surface color A rather minimum amount of radiating, edging away, or erosion of the surface. On descent, both of us remarked that we could see a very large amount of very fine dust particles moving about. It was reported beforehand that we would probably see enough gassing from the surface after engine shutdown, but as I recall, I was unable to find that.

Still have not fully configured the voice communications, however, we are getting telemetry - good telemetry from Tranquiltity Base showing a cabin pressure of 5 pounds per square inch, temperature of 60 degrees. We expect to establish communications before too long. During this period the crew is removing the portable life support systems, checking over their spacecrafts systems, getting ready for jettisoning equipment from Tranquillity Base. The cabin will be depressurized before too long and equipment will be jettisoned onto the lunar surface.

Tranquility, this is Houston. Did you copy by mark at 114:31?

TRANQUILITY
Roger. Thank you, and our mission timer is ready now.

CAPCOM
Roger. Very good. And, I've got a consumables update for you if you are ready to copy. Over.

TRANQUILITY
Okay. Go ahead.

CAPCOM
Okay. RCS alpha is 81 percent, RCS bravo 75 percent. Coming up on 115.0 is GET. Descent oxygen is 31.8 pounds or 59 percent. Descent amp hours 858, and ascent amp hours 574. Over.

TRANQUILITY
Roger. Copy. Thank you very much.

CAPCOM
Roger. Out.

CAPCOM
Tranquility, this is Houston. We also have a set of about 10 questions relating to observations you made, things you may have seen during the EVA. We can either discuss a little later on this evening or sometime later in the mission. It's your option. How do you feel? Over.

TRANQUILITY
I guess we can pick them up now.

CAPCOM
Okay, and your friendly green team here is pretty well been relieved by your friendly maroon team, and I'll put Ward on with the questions.

TRANQUILITY
Okay. Thank you, Bruce.

CAPCOM
Tranquility, Houston. First question here is your best estimate of the yaw on the - of the LM as compared to the nominal of crew flight plan. Over.

TRANQUILITY
We got 13 degrees left on the ball, and I think that's probably about right. Looking at the shadow, we probably have about 13 degrees left of the shadow.

CAPCOM
Roger, that's 13 degrees left of the shadow. And, next question relates to the depth of the bulk sampling that you obtained near the first part of the EVA, and any changes in composition that you might have observed during the bulk sampling interval. Over.

TRANQUILITY
I'm not sure I understand that question, but we got a good bit of the ground mass in the bulk sample plus a sizeable number of selective rocks of different types.

CAPCOM
Roger, Neil. One of the implications here is the depth from which the bulk sample was selected. Did you manage to get down there several inches or nearer the surface? Over.

TRANQUILITY
We got some down from as much as 3 inches in the area where I was looking at (garbled)

APOLLO 11 MISSION COMMENTARY    7-21-69     CDT 3:03  -  GET 114:21  -  TAPE 385/2

TRANQUILITY
the variation with depth at ... with the bulk sample, that there really was an appreciable difference, and I didn't run into any hard bed. Later on, other types and other areas where I got just a short distance - an inch or two - and couldn't go any further.

CAPCOM
Roger. Believe we understand down as deep as 3 inches, did not hit any hard bed, and no significant changes in composition to that depth. Next question, the second SRC was packed rather hurriedly due to the time limitations, and wonder if you would be able to divide any more detailed description of the samples which were included in the second SRC. Over.

TRANQUILITY
We got 2 core tubes and a solar wind, and about half of a big sample bag full of assorted rocks which I picked hurriedly around the area. I tried to get as many representative types as I could.

CAPCOM
Roger, Neil. Next topic here relates to the rays which luminate from the DPS engine burning area. We were wondering if the rays luminating from the - beneath the engine are any darker or lighter than the surrounding surface. Over.

TRANQUILITY
The ones that I saw back in the back end of the spacecraft appeared to be a good bit darker, and of course, viewed from the aft end, well they did have the sun shining directly on them. It seemed as though the material had been baked somewhat and also scattered in a radially outward direction, but in that particular area, this feature didn't extend more than about 2, maybe 3 feet, from the skirt of the engine. Over.

CAPCOM
Roger. Understand that near the aft end up to the eve, that the rays did appear to be darker. I understand, Buzz, that these were - this was the appearance of the material which had been uncovered by the rays that appeared darker for 2 or 3 feet extending out. Is that correct?

TRANQUILITY
No, I wouldn't say it was necessarily material that had been uncovered. I think some of the material might have been baked or in some way covered to be more cohesive and perhaps go together or something - I don't know. Now, in other areas, before we started traveling around out front, why we could see that small erosion had taken place in a radially outward direction, but it had left no significant mark on the surface other than just having eroded it away. Now, it was different back in the - right under the skirt itself. It seems as though the surface had been baked in a streak fashion, and I think a couple of pictures on film will show that. But, that didn't extend very far. Over.

CAPCOM
Roger, Tranquility. And, this

APOLLO 11 MISSION COMMENTARY    7-21-69     CDT 3:03  -  GET 114:21  -  TAPE 385/3

CAPCOM
is great concern that you've described or at least suggested - your suggestion was that it was due to the heat of the engine at any rate. Next subject, did - -

TRANQUILITY
I believe so.

CAPCOM
Roger. Next subject, did either of the solar panels on the PSE touch the surface of the moon during deployment? Over.

TRANQUILITY
I think that two corners did touch just when it was deployed but both of them did come out at the same time. It unfolded a little unevenly and of course the crane that it was on was a little bit - not quite as level as it was - as I would like to have it. I think that two corners did touch to about 1 inch, 3/4 to 1/2 an inch deep and maybe along the bottom, it might have been maybe 3 inches leaving a small triangular coating on two of the corners, and I think these are on the western ones. Over.

CAPCOM
Roger. Understand the description and the next subject on the 2 core tubes which you collected, how did the driving force required to collect these two - -


END OF TAPE


APOLLO 11 MISSION COMMENTARY    7-21-69     CDT 3:14  -  GET 114:42  -  TAPE 386/1

CAPCOM
- the two core tubes which you collected, how did the driving force required to collect these tubes compare? Was there any difference? Over.

TRANQUILITY
Not significantly. I could get down to about the first 2 inches without much of a problem and then as I would pound it in about as hard as I could do it and the second one took 2 hands on the handle and I was putting pretty good dents in the top of the extension rod and it just wouldn't go much more than - I think the total depth might have been about 8 or 9 inches. But even there it didn't for some reason it didn't seem to want to stand up straight. In other words, I'd keep driving it in and it would dig some sort of a hole but it wouldn't - just penetrate in a way that it would support it and I'd keep it from falling over if that makes any sense at all. It didn't really to me. Over.

CAPCOM
Roger, Buzz. I think I've got the picture. You indicate that little difference between the two samples and that in each case you got down about 2 inches without any problems and then had to continuing hammering rather vigorously in order to continue driving it into a total depth of 8 or 9 inches and even at that point the rods did not want to stay vertical. That they'd tend to fall over on you even after pounding in that far. Is that correct?

TRANQUILITY
Yeah, that's about it. It wasn't a rapid change in resistive force. And also I noticed when I took the bit off that the material was quite well packed, a good bit darker, and it - the way it adhered to the cord tube gave me the distinct impression of being moist. Over.

CAPCOM
Roger. I understand the general impression of being moist as packed in the cord tube. Next question. We did copy your comments prior to the EVA of your general description of the area. We wonder if either of you would have anymore lengthy description or more detailed description of the general summary of the geology of the area. Over.

TRANQUILITY
We'll postpone our answer to that one until tomorrow, okay.

CAPCOM
Yes indeed. That will be fine. Just a couple more here and I think these may not be quite as lengthy as number 7 there. Can you estimate the stroke of the primary and secondary struts? Over.

TRANQUILITY
Well, I could do it like this. About all the struts are about equally stroked and the heighth from the ground to the first step is about 3 feet or maybe 3 and 1/2 feet.

CAPCOM
Roger. Understand, Neil. Next topic, just after landing you pointed out that there was a hill to the west along the plus Z axis from the left. Are there

APOLLO 11 MISSION COMMENTARY    7-21-69     CDT 3:14  -  GET 114:42  -  TAPE 386/2

CAPCOM
large rocks in that direction that might block the solar ray during the sunset - as sunset approaches in your locality - are there any large rocks that might tend to obscure the ray. Over.

TRANQUILITY
No, I don't believe so. I think that it's about as level as any other area is that we chose.

CAPCOM
Roger.

TRANQUILITY
There's nothing large anyway that's going to get in the way.

CAPCOM
Roger. Copy. That's also the way it appears from the television I think and now the final question. You commented, Neil, that on your flight to the landing spot you had passed over a football field size crater containing rather large blocks of solid rock perhaps 10 to 15 feet in size. Can you estimate the distance to this football size crater from your present position? Over.

TRANQUILITY
I thought we'd be close enough so that when we got outside we could see its rim back there but I couldn't. But I don't think that we're more than a half mile beyond it. That is a half mile west of it.

CAPCOM
Roger, so you estimate your present position less than a half mile approximately west of this large crater. Over.

TRANQUILITY
That's correct.

CAPCOM
Okay, you all. That takes care of the questions from our geologists for tonight and unless you have something else that will be all from us for the evening. Over.

TRANQUILITY
Okay, thank you.

PAO
The CAPCOM there was astronaut Owen Garrett, one of the group of five scientists astronauts selected in 1965.

CAPCOM
Tranquility Base, Houston. We've now collected all the ranging data that we can use and you can go back to caution and warning and able. Over.

TRANQUILITY
Roger, will do.

CAPCOM
Tranquility Base. Houston. Over.

TRANQUILITY
Go ahead, Houston.

CAPCOM
Roger. A few more verifications, here. Can you - will you verify that the disk with messages was placed on the surface as planned, and also that the items that are listed in the flight plan, all of those listed there were jettisoned. Over.

TRANQUILITY
All that's verified.

CAPCOM
Roger. Thank you and I hope this will be a final good night. Okay.

PAO
Tranquility Base has confirmed that they left on the lunar surface all the items they had planned to. We have said good night to Neil Armstrong and Buz Aldrin. We will continue to monitor throughout this rest period which is scheduled to end at about 122 hours elapsed time. We're now 114 hours 53 minutes. Should there be any further conversations with either Tranquility Base or Columbia, we will come back up and bring those to you. This is Mission Control, Houston.

This is Apollo Control at 115 hours 50 minutes. It's been almost an hour since we said good night to Tranquility Base. Dr. Kenneth Biers, the flight surgeon on this shift, reports that he does not believe that Neil Armstrong is asleep yet. From his heartrate, he thinks he's resting and perhaps dozing from time to time, but he doesn't believe that he is asleep. Neil is the only one being monitored in Tranquility Base. There is no biomedical instrumentation for Buzz Aldrin. Dr. Biers reports that Mike Collins is sound asleep in Columbia as it orbits the moon. Columbia has just entered its 21st revolution of the moon. All systems on the Lunar Module are in good order, showing cabin pressure of 4.9 pounds per square inch, cabin temperature 62 degrees Fahrenheit. We have not heard from Tranquility Base since saying good night and we have not attempted to call them. This is Mission Control, Houston.

This is Apollo Control at 116 hours 50 minutes. All systems in both Columbia and Tranquility Base still operating very well. No problems. Dr. Kenneth Biers' report is the same as the one an hour ago. The data from Neil Armstrong indicates that he is resting, but he is not believed to be asleep, not following the pattern of sleep, but he is resting. Cabin pressure is holding steady at 4.9 pounds per square inch, temperature at 62 degrees Fahrenheit. The consumables in Tranquility Base are still in good shape, showing 45 and a half per cent of the descent water still remaining, the water very important for cooling on the lunar surface. Showing 63 per cent of the oxygen supply in the descent stage still remaining. Both of those consumables in the ascent stage very high - have not been used yet. Two water tanks in the ascent stage, each one showing 97.6 per cent; the other showing 98.4. Two oxygen tanks in the ascent stage, one reading 93 and a half per cent, the other 96.8 per cent. Mike Collins still asleep in Columbia. At 116 hours 52 minutes, all still going well with both spacecrafts. This is Mission Control, Houston.

This is Apollo Control at 117 hours 54 minutes. All continues to go well with both Columbia orbiting the moon, now in its 22nd revolution, and Tranquility Base on the surface of the moon. Flight surgeon Dr. Kenneth Biers says his data continues to indicate that Neil Armstrong may be dozing but he's sure that he is not sleeping soundly or well. Heart rates have been down in the 50's at times, but have not stayed there very long. He believes he may be sleeping fitfully and dozing, but stirring around quite a bit. Mike Collins still sleeping in Columbia and the Lunar Module Pilot Buzz Aldrin is not instrumented so the doctors cannot determine whether he's asleep or not. Cabin pressure in the Lunar Module still holding steady at 4.9 pounds per square inch. Temperature has dropped one degree since last report, now reading 61 degrees Fahrenheit.

Flight controllers here in Mission Control Center continue to monitor the systems of Eagle at Tranquility base consistently and of Columbia when that spacecraft is within acquisition on the front side of the moon. And they are in acquisition of Columbia telemetry now, it's in it's 22 revolution. Everything continuing to go very well. All systems normal. Mike Collins is still alseep, very well, in Columbia. Neil Armstrong sleeping fitfully, if indeed he is alseep at all at Tranquility base. Throughout this rest period the cabin pressure has held very steady at 4.9 in the lunar module.

CAPCOM
Columbia, Columbia, good morning from Houston.

COLUMBIA
Good morning.

CAPCOM
Hey Mike, how's it going this morning?

COLUMBIA
How goes it?

CAPCOM
Real fine.

COLUMBIA
(garbled) How's it going with you?

CAPCOM
Real fine here. Columbia, request P00 in accept. We'll shove the state vector in for you right away.

CAPCOM
Okay, it's coming up now, Columbia. We're going to keep you a little busy here. As soon as we get the state vector in we'd like you to go ahead and do a P52 option 3 on this night pass, and then when you come on around the other side there we'll give you some landmark tracking information on prime 130.

COLUMBIA
Very good.

CAPCOM
And for your information we're also going to have Tranquility Base do a P52 when you come around the other time, and I have the P22 information if you are ready to copy.

COLUMBIA
Go ahead.

CAPCOM
Okay, track landmark 135 using P22, and for information this will properly position your rendezvous radar transponder. T1 is 122 plus 16 plus 05 - okay, stand by.

CAPCOM
Columbia, Houston. The computer is yours.

COLUMBIA
Okay, and I'd like grid square of this crater 130 prime. Over.

CAPCOM
Columbia, Houston. Say again about 130 prime.

CAPCOM
Columbia, Houston.

COLUMBIA
Go ahead.

CAPCOM
Roger. I have a T1 and T2 times and also the longitude of the 130 prime. We're working on the grid squares and we'll get them shortly.

COLUMBIA
Ready to copy.

CAPCOM
Okay, T1: 122 plus 16 plus 05. Tango 2: 122 plus 21 plus 11 and 6 miles north of track. Do you want your NOUN 89 values?

COLUMBIA
Yes, please.

CAPCOM
Columbia, affirmative, and at the T1 time put your rendezvous radar transponder switch to OPERATE.

COLUMBIA
All right.

CAPCOM
And this 130 prime is the same one that you tracked prior to descent. Over.

COLUMBIA
Okay. You've updated your information as to the LM's position and this is your best estimate of where the LM is. Is that correct?

CAPCOM
Columbia, that's negative. This 130 is the little bitty crater there that you tracked - John Young's crater - that you tracked prior to descent. And we want that -

COLUMBIA
Fine, okay. You've given up looking for the LM.

CAPCOM
Affirmative. We want this for one last fix on your plane.

COLUMBIA
All right, fine, Understand. Thank you.

CAPCOM
And when the LM does his P22 on your transponder, well then that will be our last shot at the LM's position.

COLUMBIA
Roger, understand. Do you care whether my transponder is on before T1?

CAPCOM
Roger, it'll be on WARMUP prior to that time and and you can go to OPERATE any where around that time.

COLUMBIA
Yes, I get it, it's on its 24 minute warmup now.

CAPCOM
Roger.

CAPCOM
And Houston, the computer is yours, you can go to BLOCK any time.

COLUMBIA

This is Apollo Control. Spacecraft Columbia has gone behind the moon on the twenth third lunar revolution. Be acquired again at - well, let's see now, it looks like we don't have acquisition table up yet for next rev. During this pass and the short conversation toward the end of the front side pass with Columbia, the network transmitters have been arranged so that the transmissions would not disturb the crew of Eagle who at this time should be asleep. Not since Adam has any human known such solitude as Mike Collins is experiencing during this 47 minutes of each lunar revolution when he's behind the moon with no one to talk to except his tape recorder aboard Columbia. While he waits for his comrades to soar with Eagle from Tranquility Base and rejoin him for the trip back to earth, Collins, with the help of flight controllers here in Mission Control center has kept the command module's system going "pocketa-pocketapocketa".

CAPCOM
How is the resting stand up there, or did you get a chance to curl up on the engine camp?

EAGLE
Roger, Neil has rigged himself a really good hammock with a weight gutter, and he's been lying on the hatch and engine cover, and I curled up on the floor. Over.

CAPCOM
Roger. Copy, Buzz. We've got a couple of changes to your surface check-list here, and in general, what we're going to want you to do is P-22 tracking the command module for one last hack on your position there. This will be - in other words, P-57, P-22, and then press on (garble) with the check list, and the rest of them are a couple of minor changes in the check list. The main one being that we do not want the rendezvous radar on during the ascent, and we expect that this will take care of some of the overflow of program alarms that we're getting during descent.

EAGLE
Okay, we had the rendezvous radar in slew during descent though.

CAPCOM
Traquility Base, Houston. I missed that. Say again.

EAGLE
Roger, I say again. We had the rendezvous radar switch in the P00 position, not the LCG position.

CAPCOM
Roger, we copy that. But there's a greater duty cycle on - there's a good 15 percent duty cycle on the ascent program there, so just go ahead and leave it off. And I have the changes if you want to get out your surface check list and I can go ahead and start giving them to you.

EAGLE
Allright, go ahead. I've got it out.

CAPCOM
Okay, before we start here, request P00 and data and we'll give you some vectors.

EAGLE
You've got P00 and data.

CAPCOM
Okay, and on surface 50 will be the first change there.

EAGLE
Okay, and I understand you want us to do a P-57 option 3 and then a P-22. Is that the general idea? Over.

CAPCOM
That's affirmative, so on the surface 50 there, down at the bottom of the page, just after pro after 2 recycles, stick in a time of 1:22 plus 15, do P 22 as per ping 20 of G and N dictionary. Over.

EAGLE
Roger, understand that's 1:22 15 to P-22 as per pings 20 G and N dictionary.

CAPCOM
Roger. Okay let's skip on over to surface 59.

EAGLE
Okay.

CAPCOM
Okay, this is going to be for one last vent on the DPS tank, so at the top of the page just after

APOLLO 11 MISSION COMMENTARY    7-21-69     CDT 10:13  -  GET 121:40  -  TAPE 395/2

CAPCOM
EPS invertor 1 close, add - okay after EPS invertor 1 closed, add prop, descent helium red flash vent close, and then after stabilization control, AELD close, add prop displays flash engine overide flash logic close. Over.

EAGLE
Roger, copy. These are 2 circuit breakers, right?

CAPCOM
Tranquility Base, affirmative. Those are just the circuit breakers at that time.

CAPCOM
Tranquility Base, Houston. Did you get those 2 on the proportion circuit breakers?

EAGLE
Roger, I have those 2.

CAPCOM
Okay, let's go over to surface 60, and then down the middle of the page, after launch guidance system recommendation from MSFN, then add the switches -

EAGLE
Roger, go ahead then.

CAPCOM
Okay. After launch guidance system recommendation from MSFN add descent propulsion fuel vent open add descent propulsion oxidizer vent open add verify talkback gray. Over.

EAGLE
Roger. Descent propellant fuel vent open, descent propellant oxidizer vent open verify talkback gray.

CAPCOM
Roger, you've got that one, so that'll be the last vent and it will continue venting. Skip over to surface 61 down there at T minus 17.

EAGLE
Roger, I'm there. Go ahead.

CAPCOM
Okay, at t minus 17, delete CB 11, AC Bus A, rendezvous radar closed wait 30 seconds, delete PGNCS rendezvous radar close, and then add updated link switch to voice backup. Over.

EAGLE
Roger, I have that. Leave those 2 circuit breakers open, and have the updated link to voice backup, and we'll make the appropiate changes on the following circuit breaker status cards.

CAPCOM
Roger, and you might add a little note down there at the bottom of the page - NOTE: - this is the bottom of page 61 - NOTE: Do not use tapemeter in PGNCS, i.e., do not place mode select switch to ping. Over.

EAGLE
Okay. We'll put it in AGS.

CAPCOM
Okay, that's all the changes we have the checklist here, I've got some - just the general notes, I'll read to you on P22, and just for some information, over.

EAGLE
Okay, and then it looks to me like we ought to get hopping on this P57.

CAPCOM
Roger, we agree wholeheartedly. And while your starting on that, I'll read, just read these notes on P22. Call P22 possible program alarm 5.6, range greater than 400 nautical miles, and then use the P22 as describing on things 20. Take option 1 in NOUN 06, and use the no update mode. Rendezvous radar will lock on at about 25 degrees elevation above the horizon. If 503 alarm occurs, designate bail. Key A proceed and allow the rendezvous radar to search for the CSM. And place the Range Altitude Monitor Switch in altitude, altitude rate to prevent the tape meter from driving into the stops. And press on.

EAGLE
Roger, I think I have that.

PAO
This is Apollo Control. A little over 2 minutes until Columbia comes over the hill again on the 24th Lunar Revolution. In that wake up call to Eagle, the crew described how they slept in the spacecraft by lying on the floor and on the engine cover. Some of the preliminary times being generated now ascent show ignition about 1 minute 26 seconds earlier than the premission flight plan. Ignition time now showing 124 hours 22 minutes 0 seconds. Burn will have a magnitude of 6,068 feet per second. Quite a bit of that will be in vertical rise and actually starting from zero feet per second on the lunar surface. The CSI maneuver behind the moon, the Concentric Sequence Initiate, CSI the acronym being for that maneuver. 125 hours 19 minutes 34 seconds. Consistent Delta heighth CDH 126 hours 18 minutes 0 seconds. Terminal Phase initiation 126 hours 57 minutes 0 seconds, and Terminal Phase Finialization or the final breaking before docking 127 hours 39 minutes 39.2 seconds. These are Ground computations. And they will be computed by the crew from radar tracking, rendezvous radar. So actually these number computed on the Ground are somewhat academic in that they will be computed in real time by the crew. We're standing by here for Capcom to resume conversation. During this up coming pass here, more definite fix on the Eagle positions will be attempted by using the rendezvous radar from the Eagle in Program 22, rendezvous radar lunar surface navigation program. The transponder on Columbia in the meantime has been warmed up. During the last revolution, Mike Collins was advised to - have the - the transponder warmed up. As of now, the exact location is somewhat vague. And perhaps this rendezvous radar exercise will give a final, more pinpoint location of where Eagle does indeed nest on the moon. We'll continue to monitor the airground circuit. We've had acquisition of signal with Columbia, so likely the conversation will increase here as we get the

APOLLO 11 MISSION COMMENTARY    7-21-69     CDT 10:23  -  GET 121:50  -  TAPE 396/2

CAPCOM
We had alot of help down there, didn't we.

PAO
This is Apollo Control. We've had loss of signal with Columbia going behind the moon. Toward the end of that pass, Apollo 11 backup commander, Jim Lovell, who's had some experience in Lunar missions came up with his congratulations with his job-well-done. He mentioned that he would be here giving moral support during the rendezvous sequence to follow. There are likely to be further communications with Eagle until the command mmodule comes around the corner again some 44 minutes from now We'll bring the circuit back up as communications resume perhaps playing catch up with tape recordings, and at 123 hours, 10 minutes ground elapsed time, 1 hour, 11 minutes to ignition this is Apollo - stand by. We may be - let's listen in again.

TRANQUILITY
Going to give you a few comments with regards to the geology question of last night. We are landed in a relatively clear crater field of elongate secondary - circular secondary craters most of which have rims irrespective of their rays and irrespective of their size. That's not universally true. There are a few of the smaller craters around which do now have a discernable rim. The ground mass throughout the area is a very fine sand to a silt. I say the thing that would be most like it on earth is the powdered graphite. Immersed in this ground mass are a wide variety of rock shapes, sizes, textures, rounded and angular, many with varying inconsistencies as I said I've seen plain - what looked to be plain basalt and particular basalt. Others with no crystals, some with small white phenocrysts, maybe one to less than 5 percent, and the bould - we are in a boulder field where the boulders range generally up to 2 feet with a few larger than that. Now, some of the boulders are lying on top of the surface, some are partially exposed, and some are just barely exposed, and in our traverse around the surface and particularly working with the scoop we can run into boulders below the surface probably buried under several inches of the ground mass.

CAPCOM
Tranquility, Houston. Roger, very fine description.

TRANQUILITY
Now I suspect this boulder field may have some of its origin with this large sharp edge rocky rim crater that we passed over in final descent. Now yesterday I said that was about the size of a football field, and I have to admit it was a little - little hard to measure coming in, but I thought that it might just fit in the astrodome as we came by it, and it runs in the

TRANQUILITY
vacinity of the - this rocky rim crater are much larger than these in this area. Some are 10 feet or so and perhaps bigger, and they are very thickly poculated out to about one crater diameter beyond the crater rim. Beyond that there is some diminishing, and even out in this area the blocks seem to run out in rows and irregular patterns, and then there are spans between them where there are considerably less surface evidence of the hard rocks. Over.

Roger, Houston, the only trouble is that the sun is in number 5, the closed one. And it appears to also be close enough to detent 6 to shine on the far side of the cone. And it completely obscures detent 6. I'm unable to use that at all.

This is Apollo Control. Here in mission control center Flight Director Glen Lunney is polling the various positions here in the control room on their readiness to go ahead with the ascent from this next pass as the command module comes around the moon, and we're some 53 minutes now away from ascent. Meanwhile back at the scientific experiment situation, another attempt is scheduled today to shoot another laser beam up to the laser retroreflector, which is the other part of the experiment package left on the moon. The seismic experiment will continue to record and send back measurements to mission control and will probably receive it's strongest signal when the ascent engine ignites and starts Eagle on it's way into lunar orbit and rendezvous with Columbia. There's considerable amount of conversation going on with the crew even though command module Columbia is behind the moon at this time. Rather than disconnect the air-ground line and be in a tape play-back mode, we'll leave a circuit up all the way through to loss of signal on the next rev when both spacecraft will go behind the moon. At 123 hours, 29 minutes, and standing by, this is Apollo Control.

This is Apollo Control. Network controller just informed the flight director that items called battle shorts have been installed around the network. These are mechanical shorts of critical power supplies and transmitters and the like, so that before they will go off-line, they'll actually burn up in critical phases of the mission. They want to get as much data as possible through the burn, so for that reason any circuit breaking funtion of the equipment is inhibited with these battle shorts. They're not a piece of apparel. In the upcoming ascent some 14 minutes from now, almost 5000 pounds of propellant will be run through the ascent engine to propel the lunar module upper stage or

EAGLE
Okay, thank you.

PAO
This is Apollo Control. We have had loss of signal with Eagle. Quite scratchy as Eagle went over the hill to complete the 25th lunar revolution as it gets to the midpoint on the lunar far side. Ascent burn just completed went quite well on time at 124 hours 22 minutes 0 seconds ground elapsed time. Coming up on this rev, approximately 10 minutes from now as a matter of fact, will be the concentric sequence initiate maneuver, CSI, which will raise the Eagle's perilune to some 45 nautical miles. Eagle now is in an orbit measuring 9.4 nautical miles at insertion or perilune, and 46.7 at apolune, This CSI maneuver will be made approximately at apolune. Therefore, the effect takes place 180 degrees later and has the effect of raising perilune to the desired 45 nautical miles. This maneuver will take place at 125 hours 19 minutes 34.7 seconds. He will have a DELTA-V or velocity change of 51.5 feet per second. All of these maneuvers, incidentally, in the rendezvous sequence by Eagle will be made by using the reaction control system of Eagle. Following the CSI at 126 hours 18 minutes 0 seconds a 9.2 foot per second burn, probably mostly a radial burn, at 126 hours 18 minutes will twist the Eagle's orbit to equal distance from the orbit of Columbia, what they call a constant DELTA height, or CDH maneuver. At 126 hours 57 minutes 00 seconds, terminal phase initiation, TPI. In this maneuver the crew visually thrusts along the line of sight toward Columbia when the line of sight is some 27 degrees above the local horizontal. This maneuver will have a magnitude of about 24.9 feet per second, and, in turn, it raises the apolune to 60.5 nautical miles, which is approximately the altitude Columbia's orbiting. Terminal phase finalization. TPF 127 hours 39 minutes 39.2 seconds. This is the start time for a series of small burns which are a combination of midcourse correction and velocity match maneuvers to bring Eagle inwith Columbia and match the velocity so that they stationkeep for a short period for photography, etc., and move on in to docking at approximately 128 hours ground elapsed time. In all of these maneuvers Mike Collins aboard Columbia is spring loaded to do what is called a mirror image maneuver approximately a minute after the Eagle is scheduled to make its maneuver, and if for some reason Eagle can not make the maneuver, Collins would do the exact same maneuver only in reverse so that Columbia would in effect begin a CSM active rendezvous with Eagle. As Eagle went over the hill on the 25th revolution, a velocity was being measured at 5410 feet per second. Eagle's weight somewhat lighter than when it started out in excess of

This is Apollo Control. Some 6 minutes 40 seconds remaining until Apollo 11 goes behind the moon on the 27th revolution. The signal from the passive seismometer, which was left on the moon by the crew of Eagle, was lost for 30 minutes beginning about 5 minutes before Eagle took off this morning. The signal was lost because of a equipment problem that the Canary Island tracking station. The Seismic equipment is back on line now, and is beginning to record lunar day surface temperatures. The dust detector recorded zero dust after Eagle lift off. The laser ground station have not yet acquired a return signal from the Laser Ranging Retro Reflector. Five minutes away from loss of signal with Apollo 11. We will continue to monitor the air-to-ground as the spacecraft goes over the hill.

This is Apollo Control at 130 hours 16 minutes. We reacquired Apollo 11 about 25 minutes ago, at 129 51. At that time Mike Collins reported that all 3 crewmen were in the command module. The transfer occuring while the spacecraft were on the back side of the moon. They had closed out the LM early and had transferred to the second coolant loop. That decision was made in mission control because the secondary loop was on, the primary loop disabled in the close out process. We did not want to have the LM docked to the CSM for an undue length of time, because the primary guidance system is not cooled. The decision was initially made to jettison the LM at 130 hours 30 minutes, however the crew continued ahead of schedule. They were ready to jettison ahead of that time, and Collins reported at 130 10 about, 17 minutes ago, that they were, had jettisoned the LM and said it had departed at several feet per second, and we heard a comment from Buzz Aldrin, that he noticed some cracks in the thermo covering around the LM tunnel, docking area, however he said it did not appear to be a structural crack but merely some cracks in the thermal covering. We are currently scheduled to perform the small reaction control system maneuver with the command and service module for seperation from the LM at 130 hours 30 minutes, or about 12 minutes from now.

This is Apollo Control at 131 hours 48 minutes. We're standing by to reacquire Apollo - Apollo 11. Acquisition should come in about 5 seconds. This revolution should be relatively quiet. We don't have a great deal of activity scheduled.

Hello, Apollo 11, Houston. We are standing by. Everything is looking great here, over.

SC
11. Roger.

PAO
This is Apollo Control. We suspect the crew is having something to eat at this time which probably accounts for the relatively quiet period. One of the things that we are watching with interest here in Mission Control is the lunar module. At the time Aldrin and Armstrong left the LM and came back into the service module, they switched over to the secondary cooling loop as part of a test that we are running to determine just how long the primary guidance and navigation system will last without cooling. The primary guidance system is not cooled on the secondary loop which provides backup cooling for the secondary guidance system and it has always been a point of interest as to just how long the primary guidance system will survive without cooling - estimates range up to several hours. The LM TEL COMM Controller reports that at this time we are seeing some rise in the PIPAS. These are the Pulse Integrating Pendulium - Pendulous Accelerometers which - the primary guidance system uses to detect changes in motion and attitude and of course they are an essential item in the - the primary guidance system. We are seeing a gradual rise in temperature but the TEL COMM engineer reports that the primary guidance system still looks very good. At the time the crew reported they were back that Armstrong and Aldrin reported that they were back in the command module, we asked them what time they did switch over to the secondary loop. Armstrong estimated that that occurred about 129 hours 40 minutes which was a little over 2 hours ago. We will continue to monitor the LM and to observe the performance of the primary guidance system. All systems on the command service module continue to function very well at this time and the same can be said for the lunar module. At the present time we show Apollo 11 in a orbit 62.5 nautical miles by 54.2. The spacecraft travelling at a speed of 5349 feet per second.

Roger Neil. Starting off, congratulatory messages on the Apollo 11 mission have been pouring into the White House from world leaders in a steady stream all day. Among the latest are telegrams from Prime Minister Harold Wilson of Great Britian and the King of Belgium. The world's press has been dominated by news of Apollo 11. Some newsmen estimate that more than sixty percent of the news used across the country today concerned your mission. The New York Times which we mentioned before has had such a demand for its edition of the paper today, even though it ran 950 000 copies, that it will reprint the whole thing on Thursday as a souvenir. And Premier Alexei Kosygin has sent congratulations to you and President Nixon through former Vice President Humphrey who is visiting Russia. The cosmonauts has also issued a statement of congratulations. Humphrey quoted Kosygin as saying "I want you to tell the President and the American people that the Soviet Union desires to work with the United States in the cause of peace." And Mrs. Robert Goddard said today that her husband would have been so happy. "He wouldn't have shouted or anything. He would just have glowed." She added, "That was his dream, sending a rocket to the moon." People around the world had many reasons to be happy about the Apollo 11 mission. The Italian police reported that Sunday night was the most crime-free night of the year. And in London a boy who had the faith to bet $5 with a bookie that a man would reach the moon Before 1970 collected $24 000. That's pretty good odds. You're probably interested in the comments your wive's have made. Neil's Ann had said about yesterday's activities, "The evening was unbelievably perfect. It is an honor and a privilege to share with my husband, the crew, the Manned Spacecraft Center, the American public and all mankind, the magnificent experience of the beginning of lunar exploration." She was then asked if she considered the moon landing the greatest moment in her life. She said "No, that was the day we were married." And Mike,

Pat said simply, "It was fantastically marvelous." Buzz' Joan said, "Apparently couldn't quite believe the EVA on the moon." She said, "It was hard to think it was real until the men actually moved, After the moon touchdown, I wept because I was so happy." But she added, "The best part of the mission will be the splashdown." In other news, and there was a little bit, another explorer Thor Heyerdahl had to give up his attempt to sail a papyrus boat across the Atlantic. The storm-damaged boat was abandoned about 650 miles from Bermuda. The speed of the craft had been reduced to about 25 miles a day and Heyerdahl said the object of the voyage had not been to provide an endurance test for the crew. Looking at the world of sports, let's see here. While you were busy the other day, Joe Namath and Football Commissioner Pete Rozelle made the announcement that Broadway Joe had agreed to sell his interest in the Bachelors III restaurant and report to the New York Jets. Joe arrived at the Jet's training camp today and had his first workout. Several other Jet players who had held out along with Joe also reported. And Davy Hill, from Jackson, Michigan, won his third major golf in as many starts in the past week. He won the Philadelphia Classic. Hill has won four tournaments so far this year and is the leading money winner this year with a cool $129 000. And in baseball, the west division of the National League remains a tight race. LA and San Francisco are one game behind league-leading Atlanta. The Astros have a record of 48 wins and 48 losses and are now in fifth place, seven games out. A twinbill between the Astros and Cincinnati last night was postponed because of rain. The Chicago Cubs are still in first place in the East Division. They lead the New York Mets by 4 and 1/2 games. And in the American League, Baltimore is breezing toward the Eastern Division title. They lead second place Boston by 11 games. Looking ahead, the All-Star baseball game is scheduled for tomorrow. And President Nixon was scheduled to see the game and then leave immediately after the game for the Pacific splashdown area, before going on his tour of Europe. And that about covers the news this day. You guys have been making most of it and I'm sure we couldn't fill you in on any of the details that you already know. Out.

This is Apollo Control at 132 hours, 29 minutes. That last string of numbers read up to the spacecraft included the information the crew will need to start them on their way back to Earth in about 2 hours, 54 minutes. The time of ignition for the transearth injection burn again is 135 hours, 23 minutes, 42 seconds. They will burn their 20,500 pound thrust service propulsion system engine for 2 minutes, 28 seconds and increasing their speed by 3283 feet per second. And our preliminary estimate is that that will put them into the Pacific Ocean at the primary landing site at 195 hours, 18 minutes, 47 seconds, ground elapsed time, or almost precisely on the flight plan. The spacecraft weight at the time they do the transearth injection burn will be 36,691 pounds. We'll continue to stand by for any communication from the spacecraft.

This is Apollo Control. At this time the crew should be involved in their pre-ransearth injection status checks. They will also be aligning the platform on their spacecraft guidance system and will be passing up the final information for the transearth injection burn computed on the ground. A few minutes ago you heard Charlie Duke advise the crew that we show the LM platform is about to go. We've mentioned that prior to leaving the lunar module the crew had deactivated the primary cooling loop placing the secondary cooling loop in operation aboard the LM. This means that the primary guidance system does not get cooling. This is part of a preplanned test to find out just how long the primary guidance system would continue to function without cooling. We had predicted in advance that it would - may not - possibly not last much longer than a hour or so, but at the time Charlie Duke reported the platform had just gone down on the LM, it had been in operation without cooling a little more than four hours. We had an approximate time from the crew of transferring to the secondary cooling loop of about 129 hours 40 minutes and we got the report from Duke that the LM guidance platform was no longer usuable at 133 hours 55 minutes. We'll continue to standby for any further conversation from the crew.

This is Apollo Control at 134 hours, 10 minutes. We have about 47 minutes, 30 seconds before losing contact with Apollo 11 as it goes behind the moon in preparation for the transearth injection burn. With the burn we would reacquire the spacecraft at 135 hours, 34 minutes, 11 seconds. Without the transearth injection burn on the upcoming revolution we would reacquire at 135 hours, 43 minutes, 50 seconds. The final figures on that burn as passed up to the crew a few minutes ago are as follows: ignition will occur at 135 hours, 23 minutes, 42 seconds. The burn duration will be 2 minutes, 28 seconds. That will add 3284 feet per second to the spacecraft velocity starting it on its path back to Earth. And we would consume about 10,000 pounds of propellant with that burn. Splash would occur according to our preliminary figures, just about precisely as predicted in the flight plan. We'll continue to monitor now for any further conversation from the spacecraft.

Sounds like there's a story behind that one, too.

SC
We'll tell you when you get back.

CAPCOM
Hello Apollo 11, Houston will you verify that you've still got the cryos, over.

SC
Roger, we've still got them.

CAPCOM
Thank you sir.

This is Apollo control at 134 hours, 32 minutes. Flight director Gene Kranz just requested his flight controllers to view all of their data, take a good look at the spacecraft, and be prepared to make go, no go recommendations shortly for the transearth injection burn. That maneuver now 51 minutes, 27 seconds away. All systems on the spacecraft looking good at this point. The cabin temperature has been running about 72 degrees. At this time, the crew is aligning the platform on their guidance system. The stable platform used as a attitude reference for the upcoming burn. We've had very little conversation both here in the control center and from the spacecraft on this pass. We'll continue to stand by and monitor.

This is Apollo Control at 134 hours 48 minutes. It continues very quiet out here in mission control. The flight controllers have been observing the crew inputs through their computer and monitoring as the crew prepares for the trans earth injection burn, scheduled to occur in about 35 minutes from now. We have now 9 minutes 20 seconds until loss of signal. The spacecraft currently traveling at a speed of 5,329 feet per second and the altitude is 62.5 nautical miles. At the time of the trans earth injection burn, the lunar module, Eagle, should be about 20 miles behind the command module.

CAPCOM
Hello Apollo 11. Houston. You've got about 8 minutes till LOS your AOS with the burn 135:34:05. No burn 135:44. Over.

COLLINS
Okay, thank you.

PAO
The crew has a go for the trans earth injection at the beginning of the 31 revolution. All systems on the spacecraft are looking very good at this point. You heard Capcom Charlie Duke advise Mike Collins that we will reacquire the spacecraft on the other side of the moon. Now with the burn the ground elapsed time of 135 hours 34 minutes and 5 seconds. Without the burn we reacquire at 135 hours 44 minutes 3 seconds. We now have 6 minutes 50 seconds until loss of signal. We will continue to monitor.

CAPCOM
Apollo 11. Houston. One minute to LOS. Go sic'em.

COLLINS
Thank you sir. We'll do it.

PAO
Thirty seconds now until loss of signal. We've had a last status check from the flight director and all around the room the word is go. We're now 26 minutes 23 seconds from the trans earth injection maneuver - 20 seconds until loss of signal.

PAO
And we have loss of signal now. We should next reacquire Apollo 11 at 135 hours 34 minutes 5 seconds. We are now 25 minutes 38 seconds from trans earth injection.
