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.

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.

00 11 02 34 CDR
Okay. We've completed the filter change, and we'll get started on the fuel cell purge, and stand by for the LM/CM DELTA-P.

00 11 02 42 CC
Roger, 11. Would you hold off on the fuel cell purge? EECOMM is saying we might not have to do that. Over.

00 11 02 51 CDR
Okay.

Hello, Apollo 11. Houston. We've just decided to delete the O2 fuel cell purge. Over.

Roger. Delete the O2 fuel cell purge.

00 11 06 21 CC
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.

00 11 07 18 CMP
Stand by one, Charlie. We'll give you something on the detent.

00 11 07 21 CC
Roger.

00 11 07 28 CMP
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?

00 11 07 42 CC
That's negative. That question's answered. Thank you much.

Okay.

Hello, Apollo 11. Houston. We have an S-band configuration for you. Over.

00 11 10 00 LMP
Roger. Go ahead.

00 11 10 02 CC
Roger, Buzz. We'd like you to place the S-band antenna OMNI A switch to the Bravo position. S-band antenna OMNI switch to the OMNI position, the high gain track to MANUAL, and the high gain angles will be yaw 270, pitch minus 50. Over.

00 11 10 27 LMP
Roger. Understand. OMNI to Baker and OMNI, MANUAL. And the angles are yaw 270, pitch minus 50, and was that narrow or wide? Over.

Hello, Apollo 11. Houston. You can terminate battery Bravo charge, and we'd like a crew status report. We're about to tell you good night. Over.

Houston, Apollo 11. The battery charging is complete, and the crew status report is as follows: radiation, CDR 11002, CMP 10002, LMP 09003; negative medication; fit as a fiddle. Over.

00 11 18 33 CC
Roger. Copy, 11. Thank you much. We'd like to ask one question. Have you tried the gas separator on the water? How is that working? Over.

00 11 18 45 CDR
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.

00 11 19 53 CMP
Okay. Maybe we'll get around to lunch.

00 12 46 08 CC
Roger, Buzz. When you stopped - or, correction - When you terminated the NOUN 65, it appears to us, you get a VERB 46 which collapsed the deadband back to 0.5. We're okay as long as you do not turn on any AUTO RCS SELECT switches. Over.

00 12 46 30 LMP
Okay. I thought that was a - better way to clear the DSKY but evidently it isn't. Roger.

00 12 46 36 CC
Roger. VERB 34 would have been a better procedure.

00 12 46 41 LMP
Yes. Thank you.

Roger, Apollo 11. Good morning.

00 22 50 32 CC
When you're ready to copy, 11, I've got a couple of small flight plan updates and your consumables update, and the morning news, I guess. Over.

Go ahead, 11.

00 22 52 10 CC
Okay, 11. This is Houston. At time approximately 22 30 in the flight plan, in your postsleep checklist, and in all other postsleep checklists, we'd like you to delete the statement that says "AUTO RCS JET SELECT, 16 to ON," and what we're doing here is picking this up in the procedure for exiting PTC that's in your CSM checklist. And in the CSM checklist on page Foxtrot 9-8: if you want to turn to that, we'd like to change the order of the steps in that. Over.

00 22 53 13 LMP
Stand by.

00 22 53 37 LMP
Okay. Page F 9-8. Go ahead.

00 22 53 40 CC
Okay. Right now it reads, "To exit G&N PTC," then you've got a pen-and-ink change that says, "AUTO RCS SELECT, 12 MAIN A and B." And you come down to the printed step 1. We'd like to take and move the "AUTO RCS SELECT, 12 MAIN A and B" down to be the second step, so the procedure would read, "Step 1, MANUAL ATTITUDE 3, ACC
EL COMMAND; Step 2 AUTO RCS SELECT, 12 MAIN A B." Step 3 would be, "Verify DAP load," and so on. Over.

00 22 54 16 LMP
Roger. I copy. Is that AUTO RCS SELECT, 12 MAIN A, MAIN B to be the ...

00 22 54 25 CC
Roger. It should be the second step in that procedure. At time 22 40, or when you get to it, we'd like to commence a charge on battery A. And at time 24 10, we have an updated attitude for your P52 and optics calibration. Over.

00 22 55 06 LMP
Okay. 24 10. Go ahead.

Roger. P52 and optics calibration attitude: roll 330.5, pitch 086.3, yaw 000.0. The nominal attitude that's pen-and-inked in for the P23 is still good. At time 25 30, approximately, after you complete P23, we're requesting a waste-water dump down to a nominal 25 percent. Over.

Roger. Okay. We note the battery charge as soon as we get around to it, and the attitude for the P52 optics CAL: roll 330.5, pitch 086.3, and yaw all zeros. The attitude for the P23 as in the flight plan is okay; and I copy your battery charge. Crew status report as follows. Sleep CDR 7, CMP 7, LMP 5.5. And we've completed the postsleep checklist. Standing by for a consumable update. Over.
