Charlie Duke (CAPCOM)

Roger, Mike. We got an update on the LAT longitude for the LM, if you're ready to copy. Over.

Charlie Duke (CAPCOM)

Roger. Columbia, it's plus 7—correction, plus 0.799 for the LAT, plus 11.730 for the longitude over two. Over.

Michael Collins (CMP)

Thank you. The altitude remain unchanged?

Michael Collins (CMP)

Does the altitude remain unchanged? …

Charlie Duke (CAPCOM)

Hello, Tranquility Base. Houston. You are stay for a T3. We have some surface block data if you're ready to copy. Over.

Neil Armstrong (CDR)

Roger. Understand we're stay for T3. Stand by.

Neil Armstrong (CDR)

Okay, Houston. Go ahead with your block data.

Charlie Duke (CAPCOM)

Roger, Tranquility. T4, 106 38 02; T5, 108 36 15; T6, 110 34 30; T7, 112 32 45. Over.

Buzz Aldrin (LMP)

Copy. T4, 106 38 07; T5, 108 36 15; T6 110 34 30; T7, 112 32 45.

Charlie Duke (CAPCOM)

Roger, Tranquility. Stand by one.

Charlie Duke (CAPCOM)

Tranquility, Houston. Say again your T4 copy. Over.

Charlie Duke (CAPCOM)

Roger. Correction on T4: 106 38 02. Over.

Charlie Duke (CAPCOM)

Hello, Columbia. Houston. We will not come up on the MSFN relay. We'd like you to come on panel 9, turn on your VHF to TR. Over.

Michael Collins (CMP)

Okay. I'm on panel 9. Ready to receive. You want me to transmit for some reason with it?

Charlie Duke (CAPCOM)

Say again, Mike. You're about two by.

Michael Collins (CMP)

Roger. Panel 9 is configured VHF, RECEIVE. You want me to transmit with the HF for some reason? Why do you want me in TR?

Charlie Duke (CAPCOM)

Columbia, this is Houston. We don't want you to transmit, Mike. We just want you in that position in case you want to talk to Tranquility. Break. Tranquility, Houston. Say again. Over.

Neil Armstrong (CDR)

Roger. I have a fairly good sized difference between battery volts on 5 and 6; 6 is reading 33.5 and 5 is reading 36.5. Is that what you expect? Over.

Charlie Duke (CAPCOM)

Tranquility, Houston. They are both coming up in voltage. No problem. We're still GO. Over.

Charlie Duke (CAPCOM)

Hello, Tranquility Base. Houston. Could you please give us a readout now of all of your descent tank pressures? Over.

Buzz Aldrin (LMP)

Okay, Houston. On descent 1, fuel and oxidizer are reading 10 psi; and descent 2, fuel is reading 10 psi, oxidizer 11 psi.

Neil Armstrong (CDR)

Houston, Tranquility Base is ready to go through the powerdown and terminate the simulated countdown.

Charlie Duke (CAPCOM)

Hello, Tranquility Base. Houston. You can start your powerdown now. Over.

Neil Armstrong (CDR)

Roger. It's in progress.

Charlie Duke (CAPCOM)

And, Tranquility Base, the White Team is going off now and letting the Maroon Team take over. We appreciate the great show. It was a beautiful Job, you guys.

Buzz Aldrin (LMP)

Roger. Couldn't of had better agreement from all of you back there.

CapCom

Go, Tranquility. Over.

Buzz Aldrin (LMP)

Roger. Our recommendation at this point is planning an EVA with your concurrence starting about eight o'clock this evening, Houston time. That is about 3 hours from now.

Buzz Aldrin (LMP)

Well, we will give you some time to think about that.

CapCom

Tranquility Base, Houston. We thought about it; we will support it. You're GO at that time. Over.

CapCom

You guys are getting prime time TV there.

Neil Armstrong (CDR)

Hope that little TV set works, but we'll see.

CapCom

Hello, Tranquility Base. Houston. Was your eight o'clock Houston time a reference to opening the hatch or starting the PREP for EVA at that time? Over.

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.

Michael Collins (CMP)

Columbia's in high gain.

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.
