Neil Armstrong (CDR)

That would be hatch opening.

CapCom

That's what we thought. Thank you much.

Neil Armstrong (CDR)

That might be a little later than that, but in other words, start the PREP in about an hour or so.

Michael Collins (CMP)

Houston, Columbia. Copy NOUN 49?

CapCom

Stand by, Columbia.

CapCom

Tranquility Base, Houston. That's fine. We are ready to support you any time, Neil. Over.

CapCom

Break. Columbia, we see the NOUN 49. Stand by.

CapCom

Columbia, Houston. We got the data. We would like a VERB 34. Over.

Michael Collins (CMP)

All right. Stand by one, Charlie, for the next one.

CapCom

Roger, Columbia. Did—How did Tranquility look to you down there? Over.

Michael Collins (CMP)

Well, the area looks smooth, but I was unable to see him. I just picked out a distinguishable crater nearby and marked on it.

Michael Collins (CMP)

It looks like a nice area, though.

CapCom

Hello, Columbia. Houston. I understand you could not see Tranquility. What were you marking on? Over.

Michael Collins (CMP)

Houston, Columbia. I say again, I could not see him. AUTO optics pointed at a spot very close to the coordinates which you gave me, so I picked a tiny crater in that area and marked on it so I will be able to have repeatable data, but I was unable to see him.

CapCom

Hello, Tranquility Base. Houston. On our DPS venting and that fuel problem, our heat exchanger is cleared up. We heard that the ice is melted, and we are in good shape now. Out.

Neil Armstrong (CDR)

Houston. Tranquility is going to put the track modes in P00 now.

CapCom

Columbia, Houston. Over.

CapCom

Columbia, Houston. We noticed you are maneuvering very close to gimbal lock. I suggest you move back away. Over.

Michael Collins (CMP)

Yes. I am going around it, doing this CMC AUTO maneuvers to the PAD values of roll 270, pitch 101, yaw 45.

CapCom

Roger, Columbia.

Michael Collins (CMP)

How about sending me a fourth gimbal for Christmas.

CapCom

Columbia, Houston. You were unreadable. Say again please.

CapCom

Columbia, Houston. Several items for you. Over.

CapCom

Columbia, Houston. First of all, we'd like a waste water dump to 10 percent on the backside. Secondly, it does not look like we are going to need any plane change at this time, so we will not be uplinking a new REFSMMAT. Third item, I would like all of your CRYO heaters to AUTO, and we are ready for a battery charge, battery BRAVO; it will last about 7 hours. If you should go to sleep, we will be terminating that BATT charge, but at the moment, we can go ahead and start the BATT charge on BATT Bravo. And a final item, for your SM RCS configuration for your rest period, register 1 for the DAP is 11111; DAP register 2, 01100. And your AUTO RCS select switches, quad Alfa, pitch jets on only, quad Bravo all on, quad Charlie and quad Delta all off. Over.

Michael Collins (CMP)

Roger. Dump waste water to 10 percent on the backside. Use prior REFSMMAT, CRYO heaters on to AUTO, battery B charge until I go to sleep. DAP is 11111, 01100. Select quads A pitch only on, C and D all up. Over.

CapCom

Columbia, Houston. Roger.

CapCom

Columbia, Houston. We will have a state vector update for you a little later. We are not prepared with it right now; and on another subject, from Tranquility Base, they are prepared to begin their EVA early. They expect to begin DEPRESS operations in about 3 hours at 108, approximately 108 GET. Over.

Michael Collins (CMP)

Sounds good to me. Tell them to eat some lunch before they go.

CapCom

Columbia, Houston. We'd like your PRD readouts when possible, and we've checked over your EM dump. It all looks okay.

CapCom

Tranquility Base, Houston. Over.

CapCom

Tranquility, Houston. We'd like your PRD readout, and we have double checked your EM dump. It all looks okay. Over.

Neil Armstrong (CDR)

Roger. Understand our E memory dump was good. CDR's dosimeter is 11014.

CapCom

Roger, Tranquility. Break. Columbia, we would like for you to REACQ with your high gain; attempt a manual lock on. Over.

Buzz Aldrin (LMP)

Houston, Tranquility here. The LMP's readout may possibly be 09017. Over.

CapCom

Tranquility, Houston. Roger. 09017 is an update on your readout.

Buzz Aldrin (LMP)

I'll let you know for sure when it goes to either 12 or 18.

CapCom

Tranquility, Houston. Roger. The medics report your latter reading, 17, appears to be the correct one. Over.

Michael Collins (CMP)

Columbia's in the high gain.

CapCom

Roger, Columbia. You're sounding much better now.

CapCom

Columbia, Houston. Request P00 in ACCEPT, and we'll uplink another state vector. Over.

Michael Collins (CMP)

Roger. Going P00 in ACCEPT.

CapCom

Columbia, Houston. Suggest you put BATT A on your BATT relay bus. Over.

CapCom

Columbia, Houston. We're through with your computer. You can go to BLOCK.

CapCom

Tranquility Base, Houston. Over.

Buzz Aldrin (LMP)

Go ahead, Houston. Tranquility Base.

CapCom

Tranquility Base, Houston. We've reviewed the checklist, and about the only change in order to advance the EVA that we've found is that you'll want to delay your lithium hydroxide change until after the EVA rather than before. Over.

Buzz Aldrin (LMP)

Roger. We'd just as soon make a change and jettison the old one. Over.

CapCom

Tranquility Base, Houston. We would like to delay that LOIO—LiOH change until after the EVA. There is a possibility you could jettison the canister when you jettison your PLSS. Over.

Buzz Aldrin (LMP)

All right. We'll plan it that way. Over.

CapCom

Roger, Tranquility.

CapCom

Columbia, Houston. Over.

CapCom

Columbia, Houston. We show your EVAP OUT temperature running low. Request you go to manual temperature control and bring it up. You can check the procedures in ECS MAL 17. Over.

CapCom

Columbia, Houston. I have a P22 update for you.

CapCom

Columbia, Houston. Your P22 AUTO—AUTO optics landmark ID on LM. T1, 106 plus 30 plus 31; T2, 106 plus 35 plus 41, 2 nautical miles south. Your TCA, 106 plus 37 plus 16. Shaft angle 357.9 and trunnion angle 44.3. Over.

CapCom

Columbia, Houston. We have your LOS in 3 minutes. AOS will be 106 plus 11. Over.

Buzz Aldrin (LMP)

Houston, Tranquility. Over.

CapCom

Tranquility, Houston. Go ahead.

Buzz Aldrin (LMP)

Roger. This is the LM pilot. I'd like to take this opportunity to ask every person listening in, whoever and wherever they may be, to pause for a moment and contemplate the events of the past few hours and to give thanks in his or her own way. Over.

CapCom

Roger, Tranquility Base.

Buzz Aldrin (LMP)

That's about ready to fall off.

Neil Armstrong (CDR)

As a matter of fact, it just doesn't look like it sunk in at all.

CapCom

Tranquility Base, Houston. We'd like some estimate of how far along you are with your eating and when you may be ready to start you EVA PREP. Over.

Neil Armstrong (CDR)

I think that we'll be ready to start EVA PREP in about a half an hour or so.

CapCom

Roger, Tranquility.

Michael Collins (CMP)

Houston, Columbia. How do you read?

CapCom

Columbia, Columbia. This is Houston.

Neil Armstrong (CDR)

Houston, this is Tranquility Base. We are beginning our EVA PREP.

CapCom

Tranquility Base, this is Houston, Roger. Copy. You're beginning EVA PREP. Break. Break. Columbia, Columbia, this is Houston. Reading you loud and clear. Over.

Michael Collins (CMP)

You're loud and clear. The waste water dump is down to 10 percent. I have a question on the P22. Do you want me to do another P22, or is all that information just for my own use in tracking the LM for photographic purposes?

CapCom

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

Michael Collins (CMP)

Okay. Fine. I'll do it. And on the ECS system, the—Whatever the problem was, it seems to have gone away without any changing of J52 sensors or anything like that. My glycol evaporator outlet TEMP is up above 50 now, and it's quite comfortable in the cockpit; so we'll talk more about that one later.

CapCom

Roger, Columbia. Did you shift into manual control, or did the problem resolve itself under AUTO control? Over.

Michael Collins (CMP)

The problem went away under AUTO.

CapCom

Roger. That's the best type. Out.

Michael Collins (CMP)

I did cycle out of AUTO into—I did cycle out of AUTO into MANUAL, back into AUTO.

CapCom

Houston. Roger. Out.

CapCom

Tranquility Base, Tranquility Base, this is Houston. Over.

CapCom

Tranquility, this is Houston. We need a second set of PRD readings so that we may establish a rate. Over.
