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

00 03 38 07 CMP
I thought it went pretty well, Houston, although I expect I used more gas than I've been using in the simulator. The turnaround maneuver - I went PITCH ACEL COMMAND and 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. During the course of that, we drifted slightly further away from the S IVB 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. But, except for using a little more gas - And I'd be interested in your numbers on that - everything went nominally.

00 03 38 53 CC
This is Houston. Roger. We copy.

00 03 43 45 CMP

And we're down to step 13, where we're waiting for the cabin pressure to be 5, or it should be roughly 5, before we turn the REPRESS package O2 valve to FILL. Instead of 5, we're running about 4.4. Over.

00 03 44 16 CC
Roger. Stand by a second.

00 03 44 55 CMP
And Houston, Apollo 11. We did put the REPRESS package O2 valve to FILL momentarily there at step 13, and we have filled the bottles back up partially. What's the pressure reading in there, Neil?

00 03 45 17 CMP
We have about 450 psi now in the three 1-pound bottles.

00 03 48 43 CC
Okay. In reference to your question on this step 13 on the decal, I understand that you have used up the contents of the REPRESS O2 package and at that time, instead of being up to 5 psi, you were reading 4.4. Is that correct?

00 03 49 07 CMP
Okay. 4.4. Yes sir.

00 03 49 11 CC
Okay. And you want to know if you can go ahead and use additional oxygen to bring the command module up to 5.0 and continue the equalization? Over.

Okay. We're pressing on with the procedure.

00 03 49 40 CC
And 11, Houston. We have a request for you. On the service module secondary propellant fuel pressurization valve: As a precautionary measure, we'd like you to momentarily cycle the four switches to the CLOSE position and then release. As you know, we have no TM or talkback on these valve positions, and it's conceivable that one of them might also have been moved into a different position by the shock of separation. Over.

Okay. Good idea. That's being done.

Greenland was clear, and it appeared to be we were seeing just the icecap in Greenland. All North Atlantic was pretty good; and Europe and Northern Africa seemed to be clear. Most of the United States was clear. There was a low - looked like a front stretching from the center of the country up across north of the Great Lakes and into Newfoundland.

Okay. I guess the view must be pretty good from up there. We show you just roughly somewhere around 19,000 miles out now.

Okay, Houston. You got to us just a little late. Our maneuver's already begun, so it's going to cost us about the same amount of fuel to stop it, no matter where we stop it, and we may as well keep going.

be coming out of two radially opposite directions from the S IVB.

00 05 13 51 CC
Roger. They're continuing with the nonpropulsion vent from the liquid oxygen tank. It would be radially opposite, then. And boosters tell me it's the continuous vent system. They're also dumping a small amount of fuel at this time. We've got about 23-1/2 minutes or so until the APS burn. Over.

Sure, be glad to. I can go back and do the whole thing and pick different stars.

Okay. It looks like an awful big one. We noticed that you'd moved star number 2 to the

tail end of the listing, and we should be marking first on star 40. Did that have anything to do with it?

00 06 40 47 CC
Negative. We don't believe so, Apollo 11. We think that this is possibly due to some TLI dispersions, and it's probably satisfactory. So go ahead and accept this. It fits our criteria anyway that if you repeat the mark and you get an equivalent size to go ahead and accept it. And this is an equivalent size error. Over.

Okay.

And, Mike, we think these large DELTA-R's, NOUN 49, you're getting is really meaningful since it's been way before TLI since we had a state vector update; and we think it's normal. Over.

Okay. Could be, Charlie. Some of the early markings, I might not have had precisely the substellar point. I think as time goes by they've been coming more accurate but old Enif here is just flat invisible.

Roger.

And, Houston, Apollo 11. Understand that the same three gimbal angles you gave me should be valid for star 45 as well. Is that affirmative?

Go ahead. Over.

Okay, Charlie. If the attitude you gave me on star number 45 - The reticle is off, I'd say, a good 30 degrees in roll, and the star is not in sight. Over.

00 07 43 44 CC
Roger. Stand by.

00 07 43 47 CMP
I think something's wrong with those attitudes.

Hello, Apollo 11. Houston. I wondered if you have AUTO optics selected. Over.

00 07 45 21 CMP
That's affirmative.

00 07 45 26 CC
Roger. Looks like to us we need a PROCEED, Mike, to get the sextant pointed at the star. Over.

00 07 45 35 CMP
Okay. Stand by.

00 07 46 30 CC
11, Houston. Those shaft and trunnion angles were exactly what we were computing on the ground. Over.

00 07 46 45 CMP
Okay. I'm going to trim up the attitude here and give it another try.

00 07 47 55 CMP
Okay. I have this star loud and clear now, Charlie, so I might as well do a bunch of marks on this one to get a good horizon count.

00 07 48 03 CC
Roger. Stand by.

00 07 48 10 CMP
It still looks like I'm far from the substellar point. However, I'm off quite a hit in roll.

00 07 48 18 CC
Roger. We'd like you to mark right where it is now, Mike, and we'd like two sets of marks on this. Over.

00 07 48 28 CMP
Okay. Fine. But the reticle is not parallel to the horizon. I'd have to move off quite a hit in order to get it parallel to that.

00 07 48 40 CC
Apollo 11, Houston. Our procedures guys are saying that the reticle does not have to be parallel. Over.

00 07 48 51 CMP
Well, then we're not at the substellar point if we're not.

00 07 48 54 CC
Roger.

00 07 51 39 CMP
Houston, you copy that NOUN 49?

00 07 51 41 CC
Roger. We see it, 11. Stand by.

00 07 52 09 CC
Apollo 11, Houston. We would like you to accept this one and every mark thereafter. Over.

00 07 52 16 CMP
Okay.

00 07 52 55 CMP
Do you need me to wait in the NOUN 49 display for any length of time?

00 07 53 01 CC
Negative.

00 07 53 01 CMP
Okay.

00 07 54 29 CMP
Okay, Charlie. I'll be glad to give you as many of these as you like.

00 07 54 34 CC
Roger. We'd like six marks on star 45, Mike, and then we'll probably go back to star 2 again. Stand by. We'll have further word on that.

00 07 54 43 CMP
Okay.

00 07 55 20 CMP
They seem to be getting smaller, Charlie. Are you sure you wouldn't like some more?

00 07 55 23 CC
Stand by, Mike.

00 07 55 28 CMP
It's no trouble.

00 07 55 31 CC
Roger. Stand by. Out.

00 07 56 07 CC
Apollo 11, Houston. We'd like you to do two more on star 45. Over.

00 07 56 14 CMP
Okay.

00 07 58 02 CMP
Okay, Charlie. There's your two more marks. Where do you want to go from here?

00 07 58 06 CC
Stand by.

00 07 58 21 CC
Hello, Apollo 11, Houston. We'd like you to go back to star number 2 with an attitude as follows: roll 1952, pitch 1239, yaw 3400. Mike, that'll give you a trunnion angle of about 31.4. Over.

00 07 58 45 CMP
Okay. I understand star number 2 and roll 195.2, itch 123.9, and yaw 340.0. Over.

00 07 58 57 CC
That's affirmative.

00 07 59 01 CMP
Okay.

00 08 02 07 CMP
Okay, Charlie. I'm there, and I've got a trunnion angle of 30.5 degrees. Again, misaligned considerably in roll and I do believe that's important to getting good marks.

00 08 02 20 CC
Stand by.

00 08 02 40 CMP
See, if my reticle's not parallel, then I'm not marking normal to the horizon and I'm not marking at the substellar point. I'm marking off somewhere else.

00 08 02 50 CC
Stand by one. Over.

00 08 02 52 CMP
Okay.

00 08 03 24 CC
Apollo 11, Houston. The ground-computed values for your shaft and trunnion are just what you're getting on the DSKY there, Mike. The horizon looks cocked off to you - You look like you're off in roll because the angles that we gave you to maneuver to, to prevent LM reflection from fouling up your optics, we feel like a - You should go ahead and mark on the stars just as is. Over.

Apollo 11, Houston. We see your termination on P23. Thank you very much. Mike, we'll have a - We're trying to work up a story here for you; we'll be with you momentarily on an explanation of what' s happening. 0ver.

00 08 08 38 CMP
Okay, Charlie. It just appears to me that you have to have a reticle tangent to the horizon at the point at which you mark or else you're not at the substellar point; you're off laterally, and therefore you're measuring a larger trunnion angle than you should.

00 08 08 56 CC
Seems so to me. Our procedures people are working on this, and we'll be back with you momentarily. Over.

00 08 09 03 CMP
Thank you, sir.

Hello, Apollo 11. Houston. Do you read? Over.

00 09 18 11 CC
Hello, Apollo 11. Houston. If you read, this attitude 000 is pretty bad for our COMM. In fact, we've lost all data with you, and unreadable on the voice. We recommend you do the P52, option 1 preferred ...

00 09 18 25 CMP
... not a very good attitude at all for COMM, and as soon as we finish our alignment, we'll maneuver it to a different attitude. Over.

00 09 18 34 CC
Roger, 11. We copy. Recommend you go to this P52, option 1 preferred, and then go to PTC attitude. Over. Then we'll get some COMM. When you get there to PTC attitude, it'll be pitch 90, yaw 0 on the high gain. Over.

Roger, 11. That was a good readback. That was the block data scheduled for 12 hours. We'd like to just say that on a flight plan update here, just to remind you of some things, and you can do them at your convenience amd then go to sleep early if you'd like. We don't have anything else planned, but we'd like to just remind you on the filter change, the O2 fuel cell purge. And we'd like a LM/CM DELTA-P and accomplish the presleep checklist.

Hello, Apollo 11. Houston. We've been noting some funnies on the O2 flow indicator transducer. We've 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 continue 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.

Stand by one, Charlie. We'll give you something on the detent.

Right now it's at CLOSED, and I lined up with CLOSED before I was at VENT; and best I can recall, it was quite accurately lined up with VENT. Would you like me to go to VENT again momentarily and see where it lines up?

Yes. Mike's got a couple of comments cn that.

00 11 18 49 CMP
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 LEB, and we - mention one problem with them is that they leak at the junction between the food bag and the water filter. However, with that exception, they seem to be working pretty good. We were getting some gas through initially, and I think that was just getting the system purged out to begin with; and the last tubeful we poured was almost free of bubbles. Over.

00 11 19 31 CC
Roger. Sounds good. We'll check in on that problem with the SPAN guys and let you know in the morning. If you have to call us tonight, we'd like you to do it on DOWNVOICE BACKUP. We're configuring the MSFN for that mode; and as far as we can see, you're cleared for some z's. Over.

Okay. From Jodrell Bank, England, via AP: Britain's big Jodrell Bank radio telescope stopped receiving signals from the Soviet Union's unmanned Moon shot at 5:49 EDT today. A spokesman said that it appeared the Luna 15 space ship "had gone beyond the Moon." Another Quote: "We don't think it has landed," said a spokesman for Sir Bernard Lovell, Director of the Observatory. Washington UPI: Vice President Spiro T. Agnew has called for putting a man on Mars by the year 2000, but Democratic leaders replied that priority must go to needs on Earth. 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 judgment, 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 tourist cards to enter Mexico unless they take a bath and get haircuts. Huberto Cazaras, Chief of Mexican Immigration in Nuevo Laredo, said authorities in Mexico City, Acapulco, and other popular tourist spots have registered complaints about the hippies. By 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. Newspapers throughout the continent fill their pages with pictures of the Saturn V rocket blasting off to forge Earth's first link with its natural satellite. And the headline writers taxed their imagination for words to hail the feat. "The greatest adventure in the history of humanity has started," declared the French newspaper Le Figaro, which devoted four pages to reports from Cape Kennedy and diagrams of the mission. The tabloid Paris Jour proclaimed, "The whole word tells them bravo." The Communists daily L'Humanite led with the launch picture and devoted its entire back page to an enthusiastic Moon report describing the countdown and launch, the astronauts' wives and families, and backgrounding lunar activities.

Hempstead, New York: Joe Namath officially reported to the New York Jets training camp at Hofstra University Wednesday following a closed door meeting with his teammates over his differences with pro football Commissioner Peter Rozelle. London UPI: The House of Lords was assured Wednesday that a midget American submarine would not "damage or assault" the Loch Ness monster. Lord Nomay said he wanted to be sure anyone operating a submarine in the Loch "would not subject any creatures that might inhabit it to damage or assault." He asked that the submarine's plan to take a tissue sample with a retrievable dart from any monster it finds can be done without damage and disturbance. He was told it was impossible to say if the 1876 Cruelty to Animals Act would be violated unless and until the monster found. Over.

Roger. Mike, we've got some comments on performance of P23 for today if you've got a minute to talk.

00 23 57 20 CDR
He's all ears.

00 23 57 22 CMP
Yes. Go ahead.

00 23 57 25 CC
Okay. For today, we'd like you on P23 to make a trunnion bias determination, prior to P23 sightings as called out in procedures, and also one afterwards. Our intent here is to check out the possibility that some sort of thermal effect may be giving you errors in the angular read-out in the sextant. The bias that you get beforehand should be incorporated, that is a PROCEED on NOUN 87 after you get two consecutive measurements equal to within 0.003 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 ensure that you're getting a good angle measurement between the star and the Earth horizon, the sextant M-line, which is the line that runs through the two hash marks and is perpendicular to the R-line, should be parallel to the Earth horizon at the substellar point. And then the actual superimposition of the star upon the horizon can be made at any point in the field of view of the sextant: above, below, or on the M-line. We recommend the marks be made as rapidly as possible after AUTO maneuver. If you feel that the amount of time between the AUTO maneuver and the time you get ready to mark is excessive, or that you don't like that AUTO maneuver attitude when you get ready to mark, of course, you can use a VERB 94 - VERB 94 to get you back to the flashing 51 position to redo the AUTO maneuvers.

01 00 02 13 CMP
Okay. We're stopping PTC now and maneuvering to our P52 and optics CAL attitude. In regard to that 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 gave 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 not necessary.

01 00 02 47 CC
Roger, 11. I guess in keeping the cups of coffee score, why you get that one.

01 00 02 57 CMP
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 large attitude changes after that to get the M-line parallel. 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 processor for computing that offset and making sense out of that data, but as far as I know, we've got to have the M-line parallel to the horizon.

01 00 03 49 CC
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 standby a second, we'll give you an evaluation of what we feel you'll get today by the AUTO maneuver.

When you move into P23, we recommend that you use the CMC-computed angles for your AUTO maneuver and 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.

Houston, Apollo 11. Marking on this star, I get a NOUN 87 twice in a row of five balls, so that's sufficient for a count.

Okay. 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?

01 00 29 53 CC
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.

No. We haven't changed any canisters this morning.

Okay. Then you can plan on accomplishing that after P23 is over and you've got the LEB clear.

Houston, Apollo 11. We're in process of maneuvering to P23 in desired attitude. It likes roll 8.37, pitch 61.33, and yaw 339.87. Over.

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

01 00 41 20 CC
Roger. Is this for star 01?

01 00 41 23 CMP
That's correct.

01 00 41 29 CC
You are not getting any reflections or anything like that that would obscure your vision, are you?

01 00 41 40 CMP
Well, of course, the Earth is pretty bright, and the black sky, instead of being black, has sort of a rosy glow to it. 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 horizon so the star should be seen against the black background, it still is not visible.

01 00 42 16 CC
Roger. We copy. Standby a minute, please.

01 00 42 47 CC
11, this is Houston. Can you read us the shaft and trunnion angle off the counters?

Yes. I will be glad to. Shaft 331.2 and trunnion 35.85.

01 00 43 04 CC
Roger. Thank you.

01 00 45 35 CMP
It's really a fantastic sight through that sextant. A minute ago, during that AUTO maneuver, the reticle swept across the Mediterranean. You could see all of North Africa, absolutely clear; all of Portugal, Spain, southern France; all of Italy, absolutely clear. Just a beautiful sight.

01 00 45 54 CC

Roger. Go ahead, Bruce.

01 00 47 25 CC
On our ground computers we confirm the shaft and trunnion angle that you have as being pointed at the star. However, it looks as though that shaft and trunnion angle is also pointing into the structure of the LM, so that while you will be getting the Earth's horizon, the star ... is obscured by the LM. We recommend an AUTO maneuver to the attitudes pen-and-inked into the flight plan. Roll 1772, pitch 2982 and yaw 330.0. Over.

I've got a comment about the point on the Earth where the Sun's rays reflect back up toward us. In general, the color of the oceans is mostly uniform and it's bright and darker blue except for that region that's about one-eighth 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.

01 03 22 41 CC
Roger, Buzz. We noticed the same thing. It's very similar to looking at a light shining on something like a billiard ball or a bowling ball. You get this bright spot in the blue of the water, and that turns it to sort of a grayish color.

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.

Yes. We're far enough out now that the - I think the horizon definition variation is lost in the North.

Looks like the best way to get a steady view 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 that you're not touching it at all. It has a very slow drift, and you get a better - steadier view that way.

01 03 27 25 CC
Sounds good.

01 03 27 47 CC
How does it feel to be airborne again, Buzz?

01 03 27 51 LMP
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 like being outside, except more comfortable.

01 03 28 04 CC
It's a lot bigger than our last vehicle.

Yes. It sure is nice in here.

01 03 28 13 CC
I said it's a lot bigger than the last vehicle that Buzz and I were in.

01 03 28 17 CMP
Oh, yes. It's been nice. I've been very busy so far. I'm looking forward to taking the afternoon off. I've been cooking, and sweeping, and almost sewing, and you know, the usual little housekeeping things.

Jim, it's been a little warm in the machine throughout yesterday and last night during 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.

01 03 29 28 CC
I understand that 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. Do you have any moisture condensation or anything like that on the wall?

(GOSS NET 1) Tape 18/8 Page 87

01 03 29 40 CDR
No, we haven't been able to detect any moisture anyplace in the spacecraft. It seems to be fine.

01 03 29 50 LMP
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.

01 03 30 16 CMP
Yes, that hydrogen thing, it's - I'm not sure, but I think it's a backpressure problem. If the thing sees any backpressure at all, like when the bag is attached, well the flow rate will slowly decrease to where it's almost zero, and you wait, and you wait, and you wait for that last ounce. You think you have its 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.

01 03 30 49 CC
Understand.

01 03 30 54 LMP
In general, I think they do quite a good job, especially on the guns, in removing a lot of the hydrogen bubbles.

01 03 31 04 CC
Have the water temperatures been good? Are you getting hot water?

01 03 31 12 LMP
Yes. It seems reasonably warm.

01 03 31 17 CMP
We made three 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 three. 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 sure beats stone-cold coffee.

01 03 31 49 CMP
Jim, we've been sitting here a little over 20 minutes now, How does the thruster firing activity look? Are you ready to go on with this PTC?

Go ahead, Houston.

01 03 47 29 CC
Roger. If you're free for a couple of minutes, we have a procedure here that will let us verify the O2 flow transducer and at the same time get some more of our cabin enrichment out of the way. Over.

Stand by.

01 03 48 37 CDR
Go ahead, Houston. We're ready to copy.

01 03 48 41 CC
Roger. The primary purpose of this is, as I mentioned, to let us check out your O2 flow transducer. However, we still need about 2 hours' worth of cabin enrichment, so we'd like to keep the vent that we're going to set up going for this purpose. Okay. We want you to install the cabin vent quick disconnect which you'll find in compartment R-6, that is Romeo 6, on the urine connector on panel 251. When this is completed, verify that the waste stowage vent valve is closed, and then open or position the waste management overboard drain to the DUMP position. Over.

01 03 49 40 CDR
Okay. Understand that. Install the cabin quick disconnect out of R-6 on the 251 urine connector and verify that the waste dump valve is closed, and say again the last part.

01 03 50 02 CC
Roger. And then put the waste management overboard drain valve into the DUMP position. Over.

01 03 50 16 CDR
Roger. Put the waste management overboard drain valve to the DUMP position.

01 03 50 20 CC
Right. That's the one down on panel 251 also. And we'll watch your O2 flow on telemetry down here.

01 03 52 49 CDR
Okay, Houston. That configuration is set up.

That's ... It's in DUMP.

01 03 53 15 CC
Roger. We're not getting telemetry data from you right due to low signal strength. There it comes back. I expect it'll probably take us anywhere from 15 minutes to half an hour to see an increase in O2 flow due to the size of the cabin and of course of the small size of the drain. Over.

Go ahead, 11.

Roger. I've got the world in my window for a change and looking at it through the monocular, it's really something. I wish I could describe it properly. The weather is very good. South America is coming around into view. I can see on the - what appears to me to be upper horizon, a point that must be just about Seattle, Washington, and from there I can see all the way down to the southern tip of Tierra del Fuego and the southern tip of the continent.

01 04 07 55 CC
Roger. Sounds like you've got a beautiful view up there.

01 04 08 01 CMP
Absolutely fantastic. I hope the pictures come out. We,re rotating around where it's going out of view again.

01 04 37 23 LMP
Well, right now, after we put that gadget in, we've got it back to 0.35. Before that, we were reading on scale level. I think ours is relatively correct, at least when time comes for the water accumulator to kick in at 10 seconds, it goes on up to about 0.75, 0.8, something like that.

This is Houston. Roger. Out.

Okay. Bruce, we're coming up on the water accumulator activity, and it's going on up to 0.85, oh, about 0.95 and it reached a peak there and then gradually dropped back on down to 0.6 now, 0.4, and it looks like it's pretty well - pretty well leveling off back down to 0.35. Over.

On that 2O flow transducer down here on telemetry, our values are agreeing pretty well with what you read out onboard, and the EECOMM's have been noticing this cycle, but it still looks like the indicated rate is lower than what we would expect.

01 05 58 22 CDR
Go ahead, Houston.

01 05 58 23 CC
11, this is Houston. As a result of our venting through the waste management drain, we've concluded that your O2 flow rate sensor is, in fact, malfunctioning. I mentioned when you talked us 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've concluded that the transducer is malfunctioning. We'd like to continue the O2 flow for about another hour, shutting it off at about 31 hours GET, to get the O2 concentration in the vehicles up to - in the vehicles up to where it will be acceptable for LM checkout. Over.

01 05 59 27 CDR
Okay. Does it look to you like it just has a bias on it?

01 05 59 45 CC
Roger, 11. It does seem to be a bias. Looks like it has a fairly high threshold before it starts indicating. EECOMM seems to think, though, that for high flow rate purposes, it will still give you a relative indication during the mission. Over.

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

01 07 03 47 LMP
Okay. Understand. It's not our monitor. It must be the transmitter or the system.

01 07 03 52 CC
Roger. I guess so, Buzz. We'll have them look into it, and see if they can suggest anything.

01 07 05 12 CC
Hello, Apollo 11. Houston. We've lost our command interface with Goldstone. We'd like you to switch to 0MNI Delta. Over.

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

01 07 07 41 LMP
Roger. Understand about the camera. Say again about the O2 purge.

Hello, Apollo 11. Houston. We're just about to the limits where we can get any kind of picture at all on the OMNI's on the TV. It - The picture, I guess, would be just almost zero at this point.

01 07 15 02 CMP
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.

01 07 15 21 CC
Roger, 11. We're thinking about that.

Houston, Apollo 11. You got a cloud over the Houston area right now?

01 07 25 24 CC
Roger. We just had a really big thunderstorm here about a hour ago. Couple of storms around the area ... Over.

01 07 25 28 LMP
Yes. 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.

01 07 25 33 CC
Roger.

01 07 25 34 LMP
Yes, and it looks like the Cape has been having a little bit of rain, too.

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

01 07 25 59 LMP
That view through this sextant is fantastic. I can see Alaska right up - right up along the LM, and I'm running the crosshairs right now down the coast of California, the west coast of Mexico, Yucatan Peninsula, up around the Gulf, Florida, Cuba, down Central America, and I'm running into the stop right now, on the sextant.

01 07 26 44 CC
Roger. It sounds like a pretty fantastic view.

Roger. I'm not sure I caught all of that. Go ahead with what you have.

01 08 25 23 CC
Roger, 11. If you'll break out your alternate and contingency checklist for the CSM, we got an update to some of the erasable loads on page F2-20, Over.

01 08 25 42 LMP
Okay. Be getting that out, and you can give us the attitude for TV.

01 08 25 48 CC
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 checklist. Over.

01 08 26 29 LMP
Roger. We copy roll 21 - 61, pitch 090, yaw 000, high gain pitch plus 28, yaw 271. And we'll like this with the DELTA-V that we have in the book. Over.

01 08 26 46 CC
That's affirmative.

01 08 27 01 CMP
Charlie, Apollo 11. I have a couple of questions on stopping the PTC. It seems to me the easiest way to stop it would be - we're essentially, of course, at 0 degrees yaw and closing up to 90 degrees pitch, so it's just a question of stopping at 260 roll, roughly, and - How about for a procedure going MANUAL ATTITUDE, three to RATE COMMAND and then, seeing as how our deadband has already collapsed, I'll turn on the panel 8 RCS thrusters, at which time it should stop at whatever attitude it finds itself in. And if I do all of that as it comes up on 261 degrees roll, we should stop right there. Is that sufficient?

Go ahead.

01 08 33 14 CC
Roger, Mike. We'd like to see you go to ACCEL COMMAND on the MANUAL ATTITUDE switches. Then to turn on the AUTO RCS SELECT switches, and then go RATE COMMAND. That will prevent us from firing jets uncoupled. Over.

01 08 33 36 CMP
Okay. Fine. And I would guess go RATE COMMAND and roll first and then followed by pitch and yaw.

01 08 33 45 CC
Okay. That sounds good if - And when you get to the roll attitude desired, just go RATE COMMAND at that time and it'll stop us right on.

Yes. I agree, Charlie. That sounds right.

01 08 39 18 CMP
Go ahead, Charlie.

01 08 39 20 CC
Roger. Mike, when you were playing with the P37 a while ago and we collapsed the deadband back down, the DAP assumed that the deadband 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 procedure as we called it up to you of going ACCEL COMMAND, turning on all of the AUTO RCS SELECT switches and then RATE COMMAND, it would attempt to fly back to the pitch and yaw attitude that it had when the deadband collapsed. We can prevent that by - just immediately prior to going to RATE COMMAND on the MANUAL ATTITUDE switches, if you cycle the SPACECRAFT CONTROL switch to SCS, then back to CMC. Over.

01 08 40 13 CMP
Sounds like a winner.

01 08 40 14 CC

I'm not going to let these LM guys play with my DSKY anymore.

California looks nice. The San Joaquin Valley shows up as a real dark spot with a lighter brown on either side of it. You can't tell that it's green. It looks just sort of dark gray or maybe even real dark blue.

It looks like there's some clouds just to the west of the Sierras, northeast of Bakersfield a little bit; and crossing over into the Mojave from Bakersfield looks clear; and then as you get on further to the southeast of there, there's a few clouds.

01 08 50 48 CC
Roger, 11. Can you pick out Edwards in the sextant? Over.

01 08 51 56 LMP
Negative, Charlie. I just - I don't have that resolution. But to give you some idea, I can - on the lower Texas coast, I can see - knowing what I'm looking for, I can see Padre Island. I can just barely make out the fact that there's a thin spit of land and then there's a little dark zone which is the Laguna Madre between it and the mainland.

And also, President Nixon has reported - or declared a day of participation on Monday for all federal employees to enable everybody to follow your activities on the surface.

11, Houston. The definition is pretty good on our monitor here. The color is not too ..., at least on this set. Could you describe what you're looking at? Over.

01 10 01 31 CDR
Roger. 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 off beyond the terminator or inside the shadow. We can see the oceans with a definite blue cast, see white bands of major cloud formations across the Earth, and can see coastlines, pick out the western U.S., San Joaquin Valley, the Sierra mountain range, the peninsula of Baja California, and we can see some cloud formations over southeastern U.S. There's one definite mild storm southwest of Alaska, looks like about 500 to 1000 miles, and another very minor storm showing the south end of the screen near the - or a long ways off of the equator, probably 45 degrees or more south latitude. Can pick out the browns in the landforms pretty well. Greens do not show up very well. Some greens showing along the northeastern - northwestern coast of the United States and northwestern coast of Canada.

01 l0 03 44 CC
Roger, 11. It's a pretty good picture on clarity here. We're having - can you tell us - It appears to us that there are two distinct cloud- formations

(GOSS NET 1) Tape 22/3 Page 109

trending east/west, one approximately about along the equator, and one around 30 or so south latitude. Could you tell us exactly where those cross the landmasses? Over.

01 10 04 13 CDR
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. The other band, which stands about 30 south, correctly appears to join the 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 join it. We don't have an explanation for that banding.

01 10 04 53 CC
Roger, Neil. Thank you. It also appears that just to the left of the terminator, up in the northern hemisphere, there's a cloudband 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.

01 10 05 26 CDR
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.

You guys are doing a good job. It's a real steady picture, here. We're - Clarity is excellent. The color, it's - the clouds are - The whites are distinct. The rest if it looks like, to me anyway on the monitor I'm observing, is a fairly greenish blue is the way I'd describe it. Over.

Well, we can't observe much green from the spacecraft.

01 10 06 18 CC
Roger. On this monitor, the landmasses appear to be just a darker grayish color rather than a brown.

01 10 06 31 CDR
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,

(GOSS NET 1) Tape 22/4 Page 110

although it is true that they're tending more toward gray now than they were at the closer range.

01 10 07 03 CC
Roger, 11. We've been - I've just been vectored to another monitor and sure enough, the browns are coming in a lot more distinctly on the Eidephor that we have up on our screen in the control center. Over.

01 10 14 25 CMP
Cue cards have a no. We have no intertions 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 learning to find our favorite little corner to sit in. Zero g is 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 seems more at home.

That's why we picked up the rates in the other axes. We're going to wait in this attitude for about 20 minutes to dump out the rates again, and than we'll proceed with the VERB 49 and load our attitude that we have at the time - at this time. Over.

Roger. We've finally gotten concurrence on our problem here with 50 guys looking at it. When we were sitting in the 5018, we attempted to load the erasable before you terminated the VERB 49. So Mike, what we're going to have to do is call up the present CDU's, copy those down, and do a VERB 49, load the present, then do a PROCEED, then an ENTER, and then we can then set up ATTITUDE HOLD in step 6. Over.

01 11 58 03 CMP
Okay. I think that's what we did last time.

01 11 58 10 CC
It appeared to us that we attempted to load the erasable prior to entering on the VERB 49 which VERB 49 was still running, and it clobbered the CDU's. Over.

Roger. Mike, I think we can explain that seventenths rate. When we - the first time through, you know, we failed to go through the VERB 49, so we had a large error between our actual CDU and desired CDU in roll. And with that situation,

(GOSS NET 1) Tape 24/2 Page 128

the DAP - the vehicle will roll - will maneuver, rather, at a rate that is loaded in, which was three-tenths plus four-tenths rate, and it will limit at four-tenths 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 four tenths plus three tenths to give you the seven tenths. Over.

Okay. Thank you.

Roger, 11. We'd like to perform a waste-water dump at your convenience some time in the near future here. No particular time scheduled. Down air at the time for midcourse correction 3, which is about 53 55, we're deleting midcourse correction number 3 and all the items associated with it. For your information, the calculated value of the burn for midcourse number 3 was eight tenths of a foot per second, that is 0.8 feet per second. Canceling this, if we decide to burn midcourse correction 4, this would then give you a burn for midcourse correction 4 of 2.0 feet per second. At 53 hours we have an IMU realign P52. We're requesting that you do this while in PTC, and we plan to continue PTC throughout the day. Over.

Houston, Apollo 11. We've got the continent of Africa ... 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 northern coast of Africa. There's a rather remarkable cloud that appears in the vicinity of the border between Afghanistan and Pakistan. It's just about to go into the sunset now. It is casting quite a large shadow. It's isolated. There don't seem to be any other clouds ... the band of clouds near the tropical conversions clouds down around the equator clearly separate the clockwise and the counterclockwise cloud formations. Over.

02 00 33 57 CC

Okay. It looks as though the length of the shadow of that cloud is about the same as the width of the Persian Gulf.

(GOSS NET 1) Tape 31/5 Page 139

02 00 37 26 CC
Okay. We copy the width of the Persian Gulf, and I guess that all I can give you firsthand 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 and 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.

02 00 38 14 LMP
Okay. Maybe we ought to - next time split that in half, and put half of it on one side and half on the other or something like that.

02 00 38 25 CC
Yes. We could do that. We were actually pretty interested in seeing what the effect on PTC would be of the waste water dump. We don't recall ever having performed a waste water dump during PTC on previous missions. Over.

02 00 45 55 LMP
Roger. It came through a lot clearer through the sextant than with the monocular, and you could definitely tell it was one single cell in the latter stages of development. It must have gone up to over 50,000 feet, though. The eastern Mediterranean is phenomenally clear. You can see all the lakes; the Dead Sea stood out quite well. Over.

My guess would be the telescope's probably pretty useless, but you can differentiate in the sextant between water droplets and stars by the difference in their motions.

02 00 50 02 CC
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.

02 00 50 13 CMP
Right. I think so. Buzz is looking through it now. Just a second.

02 00 50 17 CC
Okay.

02 00 56 36 LMP
Houston, Apollo 11. It looks like at this time the sextant would be quite usable for any alignment. There's actually very few ... verticals.

02 00 56 50 CC
Roger, Buzz. How about the telescope? Is it useful now?

02 00 57 02 LMP
Well, it's not quite as useful; it never seems 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 its effectiveness. Over.

02 00 57 22 CC
Roger. What - Is this band something that's deposited on the outside of the optics? Over.

02 00 57 31 LMP
No. I see the reflection from the Sun.

02 00 57 35 CC
Roger.

02 00 57 41 CMP
The Sun bounces off the LM structure. With the LM attached, that telescope is just about useless. Those star charts that MPAD provided us, I think, would be most useful if we had to use the - if for some reason we had to mark through the telescope. We could use 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.

02 01 41 45 CC
Roger.

02 01 42 40 CC
11, this is Houston. At the time of your cyclic accumulator stroking, we were on low-bit-rate data, and consequently not receiving the O2 flow parameter. We expect that what you're seeing is probably nominal. That is, it's probably what we would expect from a transducer that's malfunctioning probably in this fashion, and it's just going to keep on getting worse like that. Nothing to worry about. We'll monitor things on the ground here. Over.

Houston, Apollo 11. Would you like to have both oxygen and hydrogen purge on? Over.

02 03 59 32 CC
11, this is Houston. Say again. Both what on? Over.

02 03 59 41 LMP
On the fuel cell purge: would you like to see both oxygen and hydrogen? Over.

02 04 00 02 CC
Apollo 11, this is Houston. Affirmative. We request hydrogen and an oxygen fuel cell purge. Over.

02 04 00 17 LMP
Okay. Any preference which first?

02 04 00 22 CC
Negative. As long as you've got the H2 purge line heaters on.

02 04 00 29 LMP
Okay. I'll go get - Go ahead with the hydrogen then.

02 04 58 29 CMP
Houston, Apollo 11. Over.

02 04 58 32 CC
Apollo 11, this is Houston. Go ahead.

02 04 58 38 CMP
Roger. You copy my NOUN 93?

02 04 58 43 CC
That's affirmative. We've got it.

02 04 58 48 CMP
Okay. I am going to go ahead and thrust then. Triangle difference is 0.01, but it's sort of difficult at three-tenths rate. I'm required to use medium speed unresolved, and it's difficult to hold the star centered long enough to get a decent mark on it.

02 04 59 15 CC
Roger. We copy. It looks okay to us.

Go ahead, Houston.

02 05 51 45 CC
Roger. I've got the morning news here if you're interested. Over.

02 05 51 51 CMP
Yes, we sure are. We're ready to copy and comment. Isn't that 2:30 there?

02 05 51 57 CC
Roger.

02 05 52 02 CDR
Okay. Go.

02 05 52 03 CC
Okay. Here we go. The interest in the Flight of Apollo 11 continues at a high level but a competing interest in the Houston area is the easing of watering rules. Mayor Louie Welch promises a lifting of lawn-watering restrictions if the rains continue. Friday is partly cloudy, and there is a 30-percent chance of thunderstorms in the afternoon. In Washington, D.C., the Senate Finance Committee approved extension of the income tax surtax, but a Senate vote on the bill - -

02 05 52 35 CMP
You cut out, Houston. You cut out.

02 05 52 40 CC

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

02 05 54 57 CMP
Loud and clear, Houston. Go ahead.

02 05 54 59 CC
Roger.

02 05 55 00 CMP
Start after the rains in Houston.

02 05 55 03 CC
Roger. In Washington, the Senate Finance Committee has approved extension of the income tax surtax, but a Senate vote on the bill currently 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 the Norwegian explorer, Thor Heyerdahl, which said that the crew of his papyrus boat, the 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, and the vessel was 725 miles east of the 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 yesterday, Thursday: St. Louis 11, Philadelphia 3; Montreal 5, over Pittsburg 4; Atlanta 12, Cincinnati 2; San Fransciso 14, and Los Angeles 13. American League: we have Baltimore 3, over Cleveland 2; Detroit 4 to Washington's 3; Minnesota 8 to Chicago 5. Boston at New York was rained out. And in Corby, England, an Irishman, John Coyle has won the world's porridge eating championship by consuming 23 bowls of instant oatmeal in a 10-minute time limit from a field of 35 other competitors. Over.

02 05 57 48 CMP
Roger. I assume Houston didn't play yesterday.

02 05 57 51 CC
That's correct.

02 05 57 55 CMP
I'd like to enter Aldrin in the oatmeal eating contest next time.

02 05 58 00 CC
Is he pretty good at that?

02 05 58 04 CMP
He's doing his share up here.

02 05 58 13 CC
Let's see. You all just finished a meal not long ago, too, didn't you?

02 05 58 20 LMP
I'm still eating.

02 05 58 24 CC
Okay. Does that - that - -

02 05 58 27 CMP
He's on his - He's on his 19th bowl.

02 05 58 30 CC
Roger. Are you having any difficulties with gas in the food bags like the 10 crew reported?

02 05 58 40 CMP
Well, that's intermittently affirmative, Bruce. We have these two 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 - the filters to start losing 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.

02 05 59 14 CC
Roger. We copy.

02 05 59 23 CMP
Their efficiency ranges anywhere from darn near perfect to terrible just depending on the individual characteristics of the food bags we're putting through them. Some of the food bags are so crimped near the entry-way that there's no way we can work them loose to prevent back pressure.

02 06 34 32 CDR
Hello, Houston. Go ahead.

02 06 34 33 CC
Roger, 11. As you've probably noticed, your coning angle in PTC mode is increased substantially as a result of the waste water dump, the fuel cell purge, and a natural coupling, so it looks like we are going to have to terminate PTC here in a little while. And we'd like to get your feeling as to whether you're still anticipating trying to send back TV signals from inside the LM; and if so, we'll try to provide an attitude that you can hold that'll give us high gain antenna lock on the Earth during the TV and LM activation period. Over.

02 06 35 18 CDR
Yes, we're still planning that activity if the cord lengths work out all right, and we'll accept those attitudes that you work up for us.

02 06 35 29 CC
This is Houston. Roger. Out.

(GOSS NET 1) Tape 35/4 Page 149

02 06 35 34 LMP
When you work up an attitude to get high gain, is there any way that we could get partial Sun in one of the two LM front windows?

02 06 35 46 CC
This is Houston. We'll have a look at it.

02 06 39 14 CC
Apollo 11, this is Houston. Over.

02 06 39 20 CDR
Go ahead, Houston.

02 06 39 21 CC
Roger. We have a TV attitude for you if you're ready to copy.

02 06 39 32 CMP
Go ahead. Ready to copy.

02 06 39 35 CC
Okay. We recommend stopping PTC at GET of 54 45 00, and this should put you at just about the right roll angle. The attitude we recommend is roll 263, pitch 090, yaw 000. This gives you the Earth out of window number 1 in the command module and places the high gain antenna in the CSM window for TV at your convenience. You will also have the Sun shining in - or shining at the hatch on the LM, and if you take down the window shades you should get some sunlight in. We're recommending wide deadband. Over.

02 06 40 36 CMP
Roger. Thank you, Houston. We'll look at that.

02 06 40 41 CC
Roger. Out.

02 06 42 53 CMP
Houston, Apollo 11. When we pass the proper roll angle, we're not going to be anywhere near zero degrees yaw. Do you want us to just stop and try until we find ourselves in and then VERB 49 the three angles you gave us?

02 06 43 06 CC
Stand by.

02 06 43 20 CC
Hello, Apollo 11. Houston. We'd like you to stop at the proper roll angle, then do a VERB 49 to the roll and pitch. Over. Correction, roll and yaw.

02 06 43 52 CMP
Houston, Apollo 11. Over.

02 06 43 54 CC
Go ahead, 11. Over.

Stand by, Charlie. Yes, we'r going to come out of PTC here at 263 roll and then do VERB 49 to thc recommended attitude.

02 06 44 58 CC
That sounds fine to us. Ovcr.

02 06 46 56 CC
Hello, Apollo 11. Houston. Before you open the pressure equalization valve, we'd like the LM/CM DELTA-P. Over.

02 06 47 06 CMP
Okay. Let me check it again. It was about 155.

02 06 47 12 CC
Roger.

02 06 47 14 CMP
I read it 158 right now, Charlie.

02 06 47 17 CC
Roger. Thank you much.

02 06 49 51 CMP
Houston, Apollo 11. We're stopping PTC at 263 ... 0.

02 06 49 59 CC
11, Houston. You're about one-by on this transmission. Say again. Over.

02 06 50 08 CMP
Houston, Apollo 11. Do you read?

02 06 51 46 CMP
Houston, Apollo 11. How do you read on the high gain?

02 06 51 50 CC
11, how do you read me? Over.

02 06 51 55 CMP
Read you loud and clear, Charlie. We just switched to HIGH GAIN, and we stopped PTC at roll 263, pitch 90, yaw 0. How do you read?

02 06 52 03 CC
Roger, Mike. You're five-by now on the high gain. We're right between the 0MNI antennas and pretty horrible COMM on the OMNI's. We got you five-by on the high gain, and we copy the PTC stoppage. Over.

02 06 52 18 CMP
Okay, fine.

02 06 52 35 CMP
Houston, we're going to open the DIRECT O2 valve and start pumping up the cabin.

02 06 52 40 CC
Roger. Copy.

02 06 53 06 CC
Apollo 11, Houston. We're going to hand over to Goldstone for uplink in about 2 minutes. We might have a momentary dropout of COMM. Over.

Alright. Can you hear our master alarm in the background? That's O2 FLOW HIGH coming through this amplifier.

02 06 53 27 CC
Roger. Copy.

02 06 53 37 CMP
That photoelectric cell is a good device. It's worked very well.

02 06 53 46 CC
11, Houston. Say again. Over.

02 06 53 50 CMP
I say that photoelectric cell amplifier for the master alarm is a good device. It's working very well, and it's a nice pleasing tone.

02 06 54 00 CC
Roger. Copy. Thank you.

02 06 54 08 CMP
Makes you almost glad to get master alarms.

02 06 55 01 CMP
Houston, Apollo 11. As a matter of curiosity, our O2 flow meter is pegged FULL-SCALE HIGH.

02 06 55 08 CC
Roger, 11. We copy that here. Over.

02 06 55 14 CMP
Okay.

02 06 55 26 CMP
Boy, that transducer's working somewhat.

02 06 55 32 CC
Roger.

02 06 55 51 CC
11, Houston. We'd like to try to attempt to correlate your O2 flow in transducer with the flow valve that you've got open. How far - How far open would you say you have the REPRESS O2? 0ver. Correction, the DIRECT O2.

02 06 56 10 CMP
Stand by, Charlie.

02 06 56 19 CMP
Okay, Charlie. It's not open very far. It's hard to give you a good reading without shunting it again, but the arrow is at about the one o'clock position. Now I reduce the flow, and I'll let it stabilize here. Right now our onboard reading is about 0.4, and that's with the arrow in the O2 valve at the two o'clock position. Would you rather have comparisons of O2 flow readings or would you rather have valve position comparisons?

02 06 56 48 CC
Roger. Stand by.

02 06 56 52 CC
EECOMM's say they'd like to look at valve positions. Over.

(GOSS NET 1) Tape 35/7 Page 152

02 06 57 01 CMP
Okay. Well, we're holding steady now at 0.3 pound per hour, and our cabin pressure is about 54; and I'll close the valve momentarily and then open it again to this position and tell you how much travel is required.

02 06 57 18 CC
Roger.

02 06 57 29 CMP
It's about 30 degrees of travel, Charlie, from the closed position, which is with the arrow pointing at about three to three-thirty, four o'clock.

02 06 57 38 CC
Roger.

02 06 57 47 CMP
Our flow is stabilized now at 0.6.

02 06 57 55 CC
Roger. We copy. We're reading the same.

02 06 58 00 CMP
Okay.

02 06 58 06 CMP
Yes, open it back to the one o'clock position.

02 06 58 10 CC
Roger.

02 06 58 31 CMP
Is that enough different positions, or you want more, Charlie?

02 06 58 36 CC
Mike, that's good - good enough. We're satisfied now. Over.

02 06 58 42 CMP
Okay.

Yes, it's loose now.

02 07 19 55 CDR
Can you see that?

02 07 19 58 CC
Roger, Neil. It's really good.

02 07 20 03 CDR
Not much light up in that area, but apparently the TV set's able to pick it up.

02 07 20 10 CC
There are some bright spots shining on the probe. Apparently Sun shafting on it that just gets just about enough for us to make it out. Over.

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

02 07 26 28 CC
Apollo 11, Houston. Do you have a little white dot in the bottom of your monitor - TV monitor? Over.

02 07 26 39 LMP

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

02 07 26 56 LMP
Okay. We might have got just a little bit of Sun in there. Is it just one small white dot?

02 07 27 01 CC
That's affirmative.

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

02 07 30 57 CC
Okay.

02 07 31 11 CC
We can see the LM umbilical connection quite well there, Buzz. We see you zooming in on one of the decals now. It's, "To reset, unlatch handle; latch behind grip and pull back two full strokes." That's about all we can make out.

02 07 31 35 LMP
Hey, you get an A-plus.

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

How about that. Just like the refrigerator.

Now we can see the helmet stowage bag - -

02 07 37 28 LMP
We don't see anything loose up there.

11, we have a good view of the window there. It looks like the Sun's finally coming through the shade.

02 07 40 00 LMP
Yes, I'm afraid it's - We're just about plus Z toward the Sun.

02 07 40 05 CC
That's affirmative. This attitude put both windows right toward the Sun - or the LM. Over.

02 07 40 15 LMP
Well, that may be good in some respects, but -

02 07 40 22 CC
We had a view, Buzz, of the utility light cord. ...

02 07 40 31 LMP
Now let me show you a view looking the other way.

02 07 40 33 CC
Roger. And we see right now the utility light or either the floodlight up there.

02 07 40 45 CC
I think now I see the utility light 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.

02 07 41 13 CC
We see you waving.

02 07 41 33 CC
11, Houston. That's really a beautiful shot.

02 07 41 46 CC
11, Houston. We didn't quite decipher that signal that just came from the CMP.

02 07 41 55 LMP
Just saying hello. On the LCG sight gage, you got about - oh, 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'd like to see? Over.

02 07 42 18 CC
Stand by. Roger, Buzz. That looks good to us. Thank you much.

02 07 42 28 LMP
It is the white index, is it not, that you're interested in comparing whether it's in the red or green?

02 07 42 34 CC
Stand by. That's affirmative, Buzz. It looks good. That's a good reading for us. Over.

02 07 42 42 LMP
Okay.

02 07 42 46 CC
We had a shot moment - a moment ago of the suit disconnect valve.

02 07 42 58 LMP
I'll open up the windows and see what the lighting condition's going to be like.

02 07 43 24 CC
11, Houston. That's a real good view we have of the AOT. You're back now, Buzz, and notice you're taking down one of the window shades. Over.

(GOSS NET 1) Tape 36/7 Page 159

02 07 43 36 CC
The light is superb.

02 07 43 37 LMP
How's the Sun coming in? How's the Sun coming in from this direction going to affect what you can see?

02 07 43 44 CC
It made it really super. The lighting is excellent in the - 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.

02 07 44 08 LMP
Well, let's - I'm turned around, why I took the shade off my side first.

02 07 44 16 CC
Roger. We copy. The light level for the TV is really excellent. Over.

02 07 44 29 CDR
Yes, the lighting in the LM is very nice now, just like completely daylight; and everything is visible. A good bit lighter than the tunnel was earlier.

02 07 44 43 CC
Roger. We got a good view now, Neil, of the DEDA; and also Buzz's ACA.

02 07 45 05 LMP
Hey, I'm pointing it at the front hatch now. Everything seems to be in place down there.

02 07 45 11 CC
Roger, we got the dump valves in view. Over.

02 07 45 13 LMP
Roger.

02 07 45 44 CC
11, Houston. We see you removing the ISA now, folding it up, putting it up on the AOT. The instrument panels are coming into view behind.

02 07 45 58 LMP
Yes, I think it'd probably be best, since we've done SPS burn, to put it back over the instrument panel instead of putting it up over the PLSS on the recharge station. Would you care to comment on that one? We could do either just as easily.

02 07 46 12 CC
Stand by. We'll have an answer for you momentarily.

02 07 46 18 CC
11, Houston. That's really a super shot of the main display.

02 07 47 17 CC
11, Houston. It's pretty hard to describe this view. It's really - really great.

02 07 47 23 LMP
Now you know how we feel.

02 07 47 30 LMP
Okay. Neil's OPS is about 57, 5800.

02 07 47 35 CC
Copy.

02 07 47 36 LMP
And mine's about 5800, also.

02 07 47 39 CC

02 07 48 04 CC
11, Houston. That's a good shot of Neil's PLSS, there. Over.

02 07 48 16 LMP
No, that's mine.

02 07 48 40 CC
11, Houston. That moment - a moment ago, we had a good shot of your PLSS, Buzz, and the two helmet stowage bags. Down behind your left shoulder, Buzz, we have the - the DSKY and the ACA.

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

Apollo 11, Houston. Buzz, it appears that you're intending to put on the Sun filter and view the Sun through the AOT. Over.

02 07 51 09 LMP
Yes, unfortunately it looks like it's down a little bit more towards ... than I can be able to see in the AOT.

02 07 51 17 CC

02 07 52 15 LMP
We got a beautiful view of the side of the command module out of the AOT looking in the left rear detent.

02 07 52 23 CC
Roger.

02 07 52 24 LMP
I can see the hatch and all the - all the EVA handrails. First time we've seen the silvery outside of the command module.

(GOSS NET 1) Tape 36/9 Page 161

02 07 52 40 LMP
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 tool B goes.

02 07 52 55 CC

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

02 07 53 O9 LMP
...

02 07 53 14 LMP
Okay. And the left detent, I can see the AO - or the rendezvous radar, and I move to the forward detent and that's about all I've got. I'm looking eyeball to eyeball.

02 07 53 25 CC
Roger.

02 07 54 08 LMP
Charlie, is there any concern about the duration that we ought to have the window shades open?

02 07 54 14 CC
Stand by.

02 07 54 17 LMP
We don't have - We don't have any circulation in here, and it might get a little on the warm side.

02 07 54 23 CC
Roger.

02 07 54 30 CMP
We'll - We'll put up a couple of hoses in the command module here and get a little circulation going.

02 07 54 36 CC
Sounds like a good idea. Over.

02 07 55 04 CC
Apollo 11, Houston. As far as the window shades go in this LM, there's 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.

02 07 55 17 LMP
That we will do.

02 07 55 52 LMP

One washer's on by the overhead.

02 07 56 49 CC
There we go. We got it now.

02 07 56 58 LMP
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 and things. Very few in each spacecraft. They were very clean.

02 07 57 14 CC
Roger. Sounds good.

02 07 57 45 CC
11, Houston. We have a good view out of the rendezvous - correction, the overhead window of the LM. We don't see anybody staring back at us, though. Over.

02 07 59 03 LMP
Charlie, can you see Mike's two eyeballs staring out through the rendezvous window?

02 07 59 11 CC
11, Houston. Stand by. We haven't picked him up yet.

You are looking through a lot of layers of glass.

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

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

02 07 59 55 CC
Okay. We see him staring back at us now. Hello, in there.

02 08 00 28 CC

02 08 02 14 CC
We can even see the barber pole on the talkbacks.

We can read the markings on the instruments for the glycol pressure, quantity, PCO2. You can even read the scale on the eight ball. Over.

02 08 02 58 CC
11, Houston. We see the cross-feed barber pole, and we have 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.

11, Houston. That's a good view of the eight ball. We see - You can even read the OFF flag, there.

02 08 04 30 CC
You can see the signal strength meter for the radar, read the numbers on it.

02 08 04 54 LMP
Houston, did you want us to test the cameras in the LM and - I was wondering about that. I saw it in the flight plan, but I'm just wondering if you want to do that on CSM power, or do you want us to take both of the 16mm cameras back in the CSM and test them there? Over.

02 08 05 18 CC
Stand by, Buzz.

02 08 05 21 LMP
As an alternative to that, why, we could wait LOI day and do it then when we transfer over to LM power.

Roger. Stand by. We'll have an answer.

02 08 05 47 CC
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 crazy, but we were looking at it 15 seconds after you broadcast it. 11, Houston - -

02 08 06 06 LMP
We understood that, Charlie.

02 08 06 08 CC
Okay. On the LM cameras, we'd like you to do it on LOI day with the LM power. Over.

02 08 06 19 LMP
Okay. That's what we'll do.

02 08 07 16 LMP
Houston, we're showing you something that came out of the Commander's 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.

02 08 07 35 CC
Roger. Stand by. We can't figure it out either.

02 08 07 46 LMP
It's got an arrow on the back, and it says "turn," but I'm afraid to turn it.

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

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

02 08 12 42 LMP
Well, it's picking up a little bit on circulation in here.

02 08 12 47 CC
What do you estimate the temperature is, Buzz? Over.

02 08 12 57 LMP
Oh, I'd say maybe 73, 75.

It's hard to tell at this density and pressure of gas, but comfort level is about the - about the same as the command module.

I can just barely see the handrail on the front porch from the position on the right-hand window.

02 08 15 59 CC

(GOSS NET 1) Tape 36/14 Page 166

02 08 16 32 LMP
No, what's happening is, we get pretty close to the window now and then, and it drives the automatic light control into the stop, I think.

02 08 16 42 CC
I think that's right.

02 08 16 51 LMP
Yes, I had the switch on OUTSIDE while I was going through the overhead window. That may be what's contributing to some of it.

02 08 16 58 CC
Roger.

02 08 17 05 CC
11, Houston. We seem to be picking up a few more dust particles now. We see them quite clearly in the screen now. Over.

Yes, I'm choking on one every so often.

And, 11, it doesn't look like you're having too much trouble with that bracket up there, Buzz.

02 08 18 41 LMP
I'll tell you, those new knobs really make it easy to twist the thing and get it cinched down quite tight.

02 08 18 50 CC
Roger.

02 08 20 06 CC
11, Houston. Buzz, how does the alignment look, there?

02 08 20 13 LMP
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 hand-holding it for the whole time.

02 08 20 29 CC
Roger. Looks like to us it's going to work real well.

Our monitor shows pretty good, clear pictures from this angle. I already found the 90-degree bracket.

02 08 24 37 CC
Roger, Neil. It's really a super picture. We've got the ACA, your ACA, the picture of the throttle, the 90-degree bracket. We see your handles, and now over to the bracket.

02 08 25 25 LMP
That's about the position we'll be putting the camera in after the initial descent on the ladder, and it'll be taken 1 frame a second for most of the EVA.

Houston copies. Out. That's a real good view of that camera.

02 08 26 03 LMP
Our monitor is a little bit wavy, so it's hard for us to tell when we're - when we've got a steady picture for you.

02 08 26 11 CC
11, we have no complaints at all. We don't see that waviness on our picture. It's just really great. Over.

02 08 26 19 LMP
Do the edges of the window look like straight lines to you?

02 08 26 22 CC
That's affirmative.

02 08 26 26 LMP
Okay. They don't in our monitor, and that leads us to make some corrections to the camera, which probably aren't required sometimes.

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

02 08 28 02 CC
Roger, Neil. We got it. It appears to us that Neil's about to check the Velcro mat, there.

02 08 28 17 CC
Okay, Buzz. We see the card up now.

02 08 28 26 LMP
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 that the timeline book that is laid down on the table in front of the data display keyboard; and it's on this timeline that we have all our procedures. But 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 new sequences in our timeline of procedures.

And we're ready to copy DOI PAD.

02 08 30 48 CC
11, that's real good camera work.

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.

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

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

02 08 32 45 CC
Standby. I think so.

02 08 32 58 CC

The traverse from the bottom of the LM to the aft bulkhead of the command module must be about 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.

02 08 37 44 CC
Roger. Must be some experience. Is Collins going to go in and look around?

02 08 37 56 CDR
We're willing to let him go but he hasn't come up with the price of the ticket yet.

02 08 38 O1 CC
Roger. I'd advise him to keep his hands off the switches.

02 08 38 08 CDR
If I can get him to keep his hands off my DSKY, it'd be a fair swap.

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

02 08 39 00 CDR
That's the Earth, and we have a very good view of it today. There are a few more cloud bands on than yesterday when we beamed down to you, but it's a beautiful sight.

02 08 39 34 CDR
We have some horizontal banding in our TV monitor. Are we transmitting that to you, or do you have a clear picture?

02 08 39 41 CC
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 is - our TV guys say is an - apparently a burned out spot in the camera, but it should come back. Over.

02 08 39 59 CDR
Roger. We have that in our monitor also.

02 08 40 20 CC
11, Houston. We do have three lines across our TV. I thought it was just a transmission problem, but everybody's telling me now that it's probably - it's on the downlink. Over.

Yes, that's the way it looks, Charlie. Same as yesterday.

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

11, Houston. We were wondering, Neil, with your closing comment on the TV, if you were going to turn it off. It indicated that you might be considering turning it back on. We were wondering whether we want to keep the lines up. Over.

02 09 00 35 CDR
Well, we want your recommendation on that, but I think we would just as soon, ourselves, terminate the TV. But if you have a commitment to keep, we'd be more than willing to turn it back on.

02 10 41 46 CDR
What - What are the updates going to apply to?

02 10 41 51 CC
Roger. We have a couple of changes on the LM mission rules NO GO for your NO GO card, Neil. One slight change on the APS/DPS fuel and TEMP pressure card, and we have a change to the procedure for the secondary radiator leak check, which is to be formed at - performed at 71 hours tomorrow, and also some indications that we have a couple of landing site obliques stowed in the wrong place. Over.

02 10 42 36 CDR
Okay. Is any of those in the flight plan? The secondary radiator, for example?

02 10 42 43 CC
That's affirmative. The secondary radiator leak check is called out in the flight plan at 71 20. That procedure is listed in your launch operations book on page 2 9, L2 9. We'd like to change that procedure. Over.

02 10 44 21 CMP
Yes, I'm with you.

02 10 44 22 CC
Okay. If no decrease in secondary accumulator quantity, secondary glycol to radiator valve to NORMAL. Next step, secondary coolant loop pump,

(GOSS NET 1) Tape 38/3 Page 180

AC 1 or AC 2. After 3 minutes, verify glycol discharge secondary pressure 39 to 51 psig. Also verify secondary EVAP out TEMP has changed. Next step, secondary coolant loop pump, OFF. Secondary glycol to radiator valve, BYPASS. That ends the procedure. Over.

02 10 45 52 CMP
Okay. I read back: monitor secondary accumulator quantity; secondary glycol radiator valve, NORMAL for 30 seconds, then to BYPASS. If no decrease in secondary accumulator quantity, secondary glycol to radiator valve to NORMAL. Secondary coolant loop pump, AC 1 or 2. After 3 minutes, verify glycol secondary discharge pressure 39 to 51 psig. Verify secondary evaporator outlet TEMP has changed. Secondary coolant loop pump, OFF. Secondary glycol radiator valve to BYPASS. And what's the reason for the change, Charlie?

02 10 46 27 CC
Roger. Stan is concerned that our present procedure as shown in the checklist does not really flow glycol through the radiator, and it - They want to verify that we do not have a plugged secondary radiator. Over.

02 10 46 48 CMP
Okay. They have any abnormal indications in that system, so far?

Houston, Apollo 11. Ready to copy your update.

02 11 19 35 CC
Roger. Stand by.

02 11 19 50 CC
Okay, Buzz. The first item is that we have indications that your landing site obliques are not in the proper position. If you'll check, we think that the intermediate scale landing site oblique is stowed in the CSM lunar landmark book. We think that the large scale landing site oblique is stowed in the back of the LM lunar surface map book. Over.

02 11 20 38 LMP
I think I heard you Charlie, but I'm not sure that I understand.

02 11 20 45 CC
Roger. According to our stowage list the - the landing site oblique should be in the transfer bag. In - But in the backup 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.

02 11 21 15 LMP
Okay. We've got three obliques. 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 horizon view and 50-degree LPD; and all three of those are in the transfer book. Over.

02 11 21 34 CC
Roger. Fine. We were wrong in our - in our backup set. We had those out of place. Looks like the onboard data's good. We just wanted to let you check on that one. We have an update on the APS/DPS fuel card that you place on the panel. It's a typo error. If you'll break out that little card, we've got the - correct that typo error. Over.

02 11 22 10 LMP
Stand by.

02 11 23 05 LMP
Okay. I got it.

(GOSS NET 1) Tape 38/5 Page 182

02 11 23 07 CC
Roger, Buzz. Under the DPS column on the pressure side, you go down to the fourth item, says pressure greater than 150 PTCA should be greater than 65 percent. Over.

02 11 23 28 LMP
Okay. That's greater than 1.8 but less than 65 and greater than 150 for greater than 65.

02 11 23 35 CC
That's affirmative. Out.

02 11 23 46 CC
And we have three items on the mission rules NO-GO card, if you're ready to copy those. Over.

02 11 24 32 LMP
Okay. I've got the mission rules NO-GO.

02 ll 24 34 CC
Roger, Buzz. First entry's on the EPS under AC bus A. The line extends all the way to high gate. Actually, the line should read - at DOI it would be NO-GO AC bus A. After that the NO-GO would be both buses. So if you will just pencil in both buses from PDI through high gate, it'll be correct for that line. Over.

02 11 25 20 LMP
Okay. I've got that: AC bus A for DOI and both buses NO-GO for PDI on.

02 11 25 28 CC
That's affirmative up until high gate. You can stop at the line in front of the column "5 minutes to low gate". Now the next line is under the G&C PGNS, pitch and roll GDA's. You can scratch that line completely. Over.

02 11 25 56 LMP
Roger. Got it.

02 11 25 57 CC
Okay, Buzz. Last entry is down under RCS, and it's a typo error under the three - in the line "three axis attitude control". If you 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.

02 11 26 38 LMP
Okay. We're stopping that at "5 minutes to low gate".

02 11 26 41 CC
That's affirmative. That completes that card. The rest of the updates are just really for your information based on our 58 hour platform - look at the platform. We are really good shape. Your GYRO's have almost no drift in them since - plotted update we were looking at X of a minus 2.24 ...

(GOSS NET 1) Tape 38/6 Page 183

Y of point plus 0.87, Z of minus 0.11. Since the update, which was based on the 52 hour P52, I believe, we gave you an X drift of plus 0.79, yaw of plus 1.06, Z of plus 0.02 ... I can see the difference between the 52 hour and the 57 hour alignments were - did not really give us enough time to get a real good or completely valid update on the drift check. So we're real satisfied with the way the GYRO's are looking. The PIPA's are looking great also. We are in real good shape with those, too. Over.

This is Apollo 11. Radio check.

Okay. Loud and clear. You cut out when you were talking about the platform - something about 52 hours and after that, we never heard you again.

02 11 32 37 CC
Roger. Guess we were changing antennas. Stand by. That's affirmative, 11. We were swapping antennas on you down here. Basically the word is that we have a real good platform, very small drift on the GYRO's, and very small drift in the PIPA's. Over.

02 11 33 00 CDR
Roger. Thank you. And I would like to have a few words of clarification if you will give them to me on the RCS ... what that change of pitch may mean.

02 11 33 14 CC
Copy. A few words of clarification on the RCS? Oh. Roger. The update there, Neil, you are speaking of about the one axis down to 5 minutes of low gate?

02 11 33 31 CDR
Yes. That's right. I'm not quite sure what that ... means beyond 5 minutes.

02 11 33 38 CC
Stand by. I'll make sure I got my story straight with Control. Stand by.

02 11 33 44 CDR
Okay.

02 11 34 33 CC
11, Houston. On the RCS, what we are saying is that if we lose control about one axis prior to low gate, we would recommend an abort. This would require a - a loss of - of two distinct jets which is not very probable, but that is what we are recommending. After low gate we would continue on. We would recommend that we continue on to attempt a landing. Over.

02 11 37 09 CC
Apollo 11, Houston. We swapped antennas on you again. I say again that we do not have any lunar surface update - book updates at this time. We're considering a few minor ones, but we're still kicking them around the MOCR. Over.

02 11 50 35 CMP
I didn't understand that. Say again.

02 11 50 38 CC
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 have had any vents or any such thing as that, that could have caused us to pick up these rates to drive us off. Over.

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

02 11 51 21 CC
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.

02 11 51 39 CMP
Okay.

Apollo 11, Houston. We hate to say it, but we'd like to terminate this PTC and start over again.

We have absolutely no idea. Over.

02 12 50 49 CMP
Okay. Did, it look like it was all right, then just all of a sudden start diverging?

02 12 50 57 CC
That's negative, Mike. If you'll look at the plot, which we'll save for you and let you see it postflight, 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 offset 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, and so we called you and started over again. Over.

02 12 51 39 CMP
Okay, no complaints. I was just curious as to what had happened.

Yes indeed. O2 fuel cell purge at 71 hours, and when you feel like copying, I've got a flight plan update containing - I guess that and some other items for you.

Okay. Stand by.

02 23 06 59 LMP
Houston, Apollo 11. Go ahead with the flight plan update.

02 23 07 05 CC
Roger, 11. This is Houston. At approximately 71 hours to 72 hours, we have you down for an eat period which I imagine is probably in progress already. 71 hours: O2 fuel cell purge; 72 hours GET: CO2 filter change number 6, secondary radiator flow check. And we'll send you up a P37 block data on a 2 hour pass, pericynthion pass, return mode abort. At 73 hours 00 minutes: stop PTC at approximately 0 degrees roll. That is, when you're ccming up on 0 degrees roll angle around 73 hours, we'd like you to stop PTC. And perform a P52 option 3 remaining in the PTC REFSMMAT for a drift check. 73 hours, 20 minutes: we'll give you a P27 update to the landing site REFSMMAT, LOI 1 state vector, and target load. 73 hours 30 minutes: maneuver to 000 roll, pitch, and yaw; high gain antenna angles will be pitch 0, yaw 335; and perform a P52 option 1 using the new landing site REFSMMAT. Resume the nominal flight plan at 74 hours GET. Over.

02 23 09 08 LMP
Okay. We'll get started on the fuel cell purge while we're eating. CO2 canister change number 6; secondary radiator flow check; copy some pads. Also at 72 hours, stop PTC 0 roll at 73; do a P52 option 3; we'll get your uplink REFSMMAT for the landing site; and at 000 - let's see, now was this with the old REFSMMAT or the new REFSMMAT?

02 23 24 14 LMP
Okay. We're ready to listen.

02 23 24 18 CC
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. The onboard PC reading is due to a known gage calibration factor between what you've actually got in the chamber and what you're reading out on the gage. 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 on board correlates to 83 psi actual. And we recommend that you stick to an LOI termination cue of 80 psi on the gage. That is, no change to the mission rules. Over.

02 23 34 12 CC
Roger.

02 23 34 16 LMP
It's quite an erie sight. There is a very marked three dimensional aspect of having the Sun's corona coming from behind the Moon the way it is.

02 23 34 27 CC
Roger.

02 23 34 31 LMP
And it looks as though - I guess what's giving it that three dimensional effect is the earthshine. I can see Tycho fairly clearly - at least if I'm right side up, I believe it's Tycho, in moonshine - I mean, in earthshine. And, of course, I can see the sky is lit all the way around the Moon, even on the limb of it where there's no earthshine or sunshine.

If you'd like to take some pictures, we recommend using magazine Uniform which is loaded with high speed black and white film, interior lights off, electric Hasselblad with the 80 millimeter lens. And you're going to have to hand hold us, I guess. We're recommending an f stop of 2.8, and we'd like to get a sequence of time exposures. Over.

Oh, very good.

02 23 56 00 CDR
And, Houston, I'd suggest that along the ecliptic line we can see the corona light out to two lunar diameters from this location. The bright light only extends out about an eighth to a quarter of the lunar radius.

02 23 56 35 CC
Roger. Understand that you can see the corona approximately 200 solar diameters out along the ecliptic, and the bright light extends out approximately one eighth to one quarter lunar radius. Over.

02 23 56 52 CDR
That's two lunar - two lunar diameters along the ecliptic in the bright part, right; a quarter to an eighth of a lunar radius out, and that's perpendicular to the ecliptic line on the South Pole.

Roger.

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. It's - the sky is full of stars. Just like the nightside of Earth. But all the way here, we have only been able to see stars occasionally and perhaps through the monocular, but not recognize any star patterns.

03 00 14 55 CDR
All right. On the secondary loop check when we went to FLOW on the 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.

(GOSS NET 1) Tape 46/7 Page 202

03 00 15 30 CC
Apollo 11, this is Houston. We believe that is normal system operation. The radiators are expected to be very cold right now and apparently the decrease you saw was due to contraction in the fluid. Over.

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 judgment, 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 suppose to have "intuition that enables you to interpret life with feeling." Buzz is to be very sociable and cannot bear to be alone in addition to having excellent critical ability. Since she didn't know at 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.

Apollo 11 is getting its first view of the landing approach. This time we are going over the Taruntius crater, and the pictures and maps brought back by Apollo 8 and 10 have given us a very good preview of what to look at here.

03 04 57 28 LMP
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 pretty fair. Looking back behind me, now, 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 Aristarchus

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

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. A crater can be seen, and the area around the crater is quite bright.

03 05 13 30 CC
Roger, 11. We copy.

03 05 14 23 LMP
Houston, Apollo 11. Looking up at the same area now and it does seem to be reflecting some of the earthshine. I'm not sure whether it was worked

(GOSS NET 1) Tape 50/3 Page 224

out to be about zero phase to - Well, at least there is one wall of the crater that seems to be more illuminated than the others, and that one - if we are lining up with the Earth correctly, does seem to put it about at zero phase. That area is definitely lighter than anything else that I could see out this window. I am not sure that I am really identifying any phosphorescence, but that definitely is lighter than anything else in the neighborhood.

03 05 15 15 CC
11, this is Houston. Can you discern any difference in color of the illumination, and is that an inner or an outer wall from the crater? Over.

03 05 15 34 CMP
Roger. That's an inner wall of the crater.

03 05 15 43 LMP
No, there doesn't appear to be any color involved in it, Bruce.

03 05 15 47 CC
Roger. You said inner wall. Would that be the inner edge of the northern surface?

03 05 16 00 CMP
I guess it would be the inner edge of the westnorthwest part, the part that would be more nearly normal if you were looking at it from the Earth.

03 05 16 20 CC

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. It was really a freshlooking 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.

Roger. We copy.

03 06 26 47 CC
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, sort of a brownish gray.

03 06 27 10 LMP
That's a good, reasonable way of 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

(GOSS NET 1) Tape 50/7 Page 228

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.

I'm flying it in SPS minimum impulse, Houston, and it's rather difficult to keep it on a constant data. The LM wants to wander up and down.

03 06 34 50 CC
Roger.

03 06 34 55 CC
And 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.

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

03 06 35 46 CC
Roger, 11. We're watching the DSKY now, and it's still coming in beautifully on the TV.

03 06 35 59 LMP
Okay. There's - on the right side of the screen at the present time, there's a triple crater with - with a small crater between the first and second; and the one at the bottom of the screen is Schubert Y. Zoom in; it does have a central peak in Schubert Y. Actually, several of them, and you can observe those plus the rim craters at the bottom of your screen.

03 06 36 36 CC
Roger. We're seeing the central peak quite clearly now.

03 06 36 53 LMP
Okay. We're zooming in now on a crater called Schubert N. Schubert N, very conical inside walls and the bottom appears to be nearly flat.

03 06 37 11 CMP
Look at data on the DSKY. It's stabilized and is holding steady now.

03 06 37 19 CC
Roger.

03 06 37 20 LMP
Looking out the window I can see a number of small craters on the bottom of Schubert N.

03 06 37 32 CMP
We're coming up on the Foaming Sea where I'll be doing some P22 marking on a crater of my choice, name of crater, Camp.

03 06 37 41 CC
Okay. We'll be watching for Neper.

03 06 37 49 CMP
And notice register 3 has reversed itself, and it's heading back the other way now without any pitch thruster firing.

03 06 37 56 CC
Roger, Mike. We confirm that you've changed the direction of your pitch rate.

03 06 38 28 CMP
Generally speaking - -

03 06 38 30 LMP
The crater - -

03 06 38 31 CMP
- - The tendency seems to be to pull the LM down toward the center of the Moon there as in a gravity gradient experiment.

It may have something to do with MASSCON's or it may just be the peculiarity of the DSKY display.

03 06 38 51 CC
Okay. We've observed the behavior of your DSKY, and I think we've got the data here to work on it. Let us grind around a little while on it, and we'll report back to you, probably in a REV or two.

03 06 39 08 CMP
Okay. Well, in the meantime, I'm going to pitch down toward 315.

03 06 39 14 CC
Roger.

03 06 39 25 LMP
Three craters - three horizontal craters that you now have in the field of view are immediately underneath the ground track. The right hand is the largest crater that you see, Dubiago P.

03 06 39 49 CC
Roger. We concur on the identification of that crater.

03 06 40 01 CC
And we show you coming up on landmark Alfa 1 here shortly.

03 06 40 11 LMP
Roger. Mike's having his first look at Alfa 1 at the present time.

03 06 40 22 CMP
Yea. It's a very bright crater. It's 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 my - Correction - the Foaming Sea easy to see coming up on it now. Crater Camp is one of the smaller ones out on the - on the floor of the Foaming Sea.

03 06 41 34 CC
Here we 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.

(GOSS NET 1) Tape 51/4 Page 233

03 06 41 48 LMP
Now the crater that's in the center of the screen now is Webb. We'd 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 that are in the bottom of it on the western wall, the wall that's now nearest the - the camera. Near the bottom of the screen, we can see a dimple crater, just on the outside. And then coming back toward the bottom of the screen and to the left, you can see a series of depressions. It's this type of connected craters that give us most interest to discover why they're in the particular pattern that they're in. I'll zoom the camera in now and try and give you a closer look at it.

03 06 42 48 CC
Roger. We're observing the dimple crater now. The central peak we can see on the Orbiter photos doesn't seem to stand out very well here.

03 06 43 02 LMP
Well, they're not central peaks. They're depressions in the center.

03 06 43 05 CC
Roger.

03 06 43 08 CMP
And you'll notice on the pitch thruster activity, I've still - I've put in a dozen mininum impulses in pitchdown, and I'm still far from correcting back to 315.

03 06 43 20 LMP
We're moving the camera over to the right window now to give you Langrenus, its - its several central peaks and -

03 06 43 29 CC
Roger. We got Langrenus in our screen now.

03 06 43 54 CC
Okay, 11. This is Houston. We're getting a beautiful picture of Langrenus now with its rather conspicuous central peak.

03 06 44 07 CMP
The Sea of Fertility doesn't look very fertile to me. I don't know who named it.

03 06 44 12 CDR
Well, it may have 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 - one of the early reasonably accurate maps of the Moon.

03 06 44 39 CC
Roger. That's very interesting - -

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

03 06 44 46 CC
Amen to that.

03 06 44 52 CC
Okay. It looks like you're coming inside now on the camera.

03 06 44 59 LMP
Well, I can't get behind to see the monitor. I'll bring the focus in, but we're 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'll be seeing coming in now. I guess there's maybe 2 or 3 minutes before power descent.

03 06 45 37 LMP
All right, that should put the LM structure about in focus, and I'm going to move it out to infinity and then expand the field of view.

03 06 46 00 LMP
Crater Secchi is out my window now, window number 2.

03 06 46 09 CC
Hello, Apollo 11. This is Houston. We show you coming up on the terminator at 78 53, about 7 minutes from now, and we've also got the LOI 2 and TEI 5 PAD's ready for you after the TV whenever you want to terminate. Over.

05 06 46 31 LMP
Roger.

03 06 46 33 CC
And we're getting a good view of the track leading into the landing site now and -

03 06 46 58 CC
Okay, And it looks like we got Secchi K, went by about 10 seconds ago; coming up on Apollo Ridge.

03 06 47 36 CC
And in the right hand portion of our screen right now, we can see Messier Alfa and Bravo with the light colored rays streaming off in one direction.

03 06 48 00 LMP
I don't know if you can make out, but in the Sea of Fertility there are a number of craters that are just barely discernible, old, old craters whose outlines are just barely able to be seen.

(GOSS NET 1) Tape 51/6 Page 235

03 06 48 14 CC
Roger. I think we can make them out. The color really enhances our ability to discern features and craters over what we see in real time on our black and white monitor.

03 06 48 31 LMP
Right. The - At these low Sun angles, there's no trace of brown, it's now returned to a very gray appearance and, like the 8 crew says, it has a look of plaster of paris to it at this Sun angle, which is completely lacking in ...

03 06 48 49 CC
Roger.

03 06 49 06 LMP
Okay. This is very close to ignition point for power descent. Just passing Mount Marilyn that - that triangular shaped mountain that you see in the center of the screen at the present time with crater Secchi Theta on top of the far northern edge of the mountain.

03 06 49 32 CC
Roger. We're getting a good view of Mount Marilyn and the Secchi Theta.

03 06 49 45 LMP
And now we're looking at what we call Boot Hill; occurs 20 seconds into the descent.

03 06 50 08 LMP
The bright, sharp rimmed crater at the very right edge of the screen, Censorinus T. Now passing the - the 1 minute point in power descent.

03 06 50 30 CC
Roger. And for your information, your current altitude is 148 nautical miles above the surface.

03 06 50 39 LMP
Don't you think?

03 06 50 43 CMP
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.

03 06 50 50 CC
I bet you could tell if you were down at 50,000 feet.

03 06 50 57 CMP
I wouldn't be surprised.

03 06 51 11 LMP
We're passing some steep ridges here. The edge of some old craters that were photographed by Apollo 10; and those - the crew of Apollo 10 was very impressed with the steepness of these ridges when they came over them at about 50,000 feet.

(GOSS NET 1) Tape 51/7 Page 236

03 06 51 36 CC
Roger. We can observe they're also steep even from this altitude. You got quite a shadow being cast by the Sun at these low angles.

03 06 51 47 LMP
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, - well, the smaller one is Censorinus.

03 06 52 09 CC
Roger. And we show you low over 1 minute from the terminator at the present time.

03 06 52 24 LMP
How's the brightness of the picture you're receiving? You think we ought to open f stop some as we approach the terminator?

03 06 52 34 CC
Yes. The brightness is still doing quite well. You can go ahead and open it up a stop or two. The automatic light level compensation seems to be working beautifully.

03 06 52 58 LMP
There's a good picture of Boot Hill.

03 06 53 02 CC
Roger. We're - -

03 06 53 03 LMP
Three minutes and 15 seconds into the descent.

03 06 53 08 CC
Roger. We're seeing Boot Hill now.

03 06 53 10 LMP
The next crater coming into the bottom, that's Duke Island right 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 down range 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.

03 06 53 57 CC
Roger. I imagine you'll get a - you'll get a real good look at that tomorrow afternoon.

03 06 54 14 LMP
Sinuous Rille is the one that was referred to in Apollo 10 as Sidewinder.

03 06 54 21 CMP

Contrast has increased and only the sunlit side of these ridges remain illuminated, while the dark sides and the shadow will become completely black.

03 06 54 59 CC
11, this is Houston. The picture's getting a little grainy now. You might go ahead and open up the f stop.

03 06 55 19 LMP
Landing point is just barely 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 abeam of the landing sight.

03 06 55 32 CC
Roger. We can just see; it looks like a little less than half of its rim right now.

03 06 55 45 CC
And we can make out just barely some features on the surface, maybe from earthshine.

03 06 55 58 CC
Are you wide open on the f stop at this time?

03 06 56 03 CMP
Yes, we are.

03 06 56 06 LMP
Yes. And it looks like we're just about to get the Sun coming into the lens, so we'll have to move the camera away.

03 06 56 12 CC
Roger.

03 06 56 14 CMP
We can't see any earthshine or any surface features at all in earthshine 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 of it. 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 they come close to the terminator.

03 06 56 42 CC
Yes. It's a very beautiful and a rugged sight that we've got on the screen now.

03 06 56 52 CMP
And I think you've got some interesting data on thruster firing versus pitch angle. It looks

(GOSS NET 1) Tape 51/9 Page 238

like that LM just wants to head down towards the surface, is all.

03 06 57 01 CC
Roger. I have a comment here that says that's what the LM was built for.

03 06 57 12 CMP
I believe!

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

In making the sextant star check this must be done between GET of 79 30 10, at which time the star comes above the horizon, and 79 52 10, which is your local sunrise due to the fact that this star's relatively close to the Sun.

I get the distinct impression, Charlie, that mare there laps up over the edge of the mountains at the shorelines.

03 08 55 42 CC
Roger. We copy.

03 08 56 40 CC
Houston. On your comment about the mare lapping up to the terrain - mountainous terrain, is that an impression like a lava flow coming in around a prominence, Neil, or is it more -looks like it's sloping up at that point? Over.

03 08 57 06 CDR
It isn't true everywhere, but there's certainly places where there seems to be a slope downward towards the shoreline on the mare. In other words, from the mare down to the shoreline is a downward slope indicating that it might be a lava flow.

All that procedure for P22 seemed to work very well. The only thing that was a little odd, is that there was some DAP thruster activity. I had pitch in ACCEL COMMAND, and roll and yaw in RATE COMMAND, and somehow, roll and yaw got excited and the DAP went into a flurry of thruster firing. We've noticed the same thing in the CMS, and just written it off as a CMS peculiarity.
