Bruce McCandless (CAPCOM)

Tranquility Base, this is Houston. In the flight plan configuration, we show that the stability control circuit breaker ATCA on panel 16 should be open at this time. Over.

Buzz Aldrin (LMP)

Houston, Tranquility. Say again which one should be closed?

Bruce McCandless (CAPCOM)

Roger. Panel 16, row 2, STAB control ATCA, that is A T C A, and it should be open at this time. Over.

Buzz Aldrin (LMP)

Housquin—Houston, Tranquility. Do you have a way of showing the configuration of the engine arm circuit breaker? Over. The reason I'm asking is because the end of it appears to be broken off. I think we can push it back in again. I'm not sure we could pull it out if we pushed it in, though. Over.

Bruce McCandless (CAPCOM)

Roger. We copy. Stand by please.

Bruce McCandless (CAPCOM)

Tranquility Base, this is Houston. Our telemetry shows the engine arm circuit breaker in the OPEN position at the present time. We want you to leave it open until it is nominally scheduled to be pushed in, which is later on. Over.

Neil Armstrong (CDR)

Houston, Tranquility Base. The CDR's PRD reads 11014.

Buzz Aldrin (LMP)

Roger. LMP reads 09018. Over.

Michael Collins (CMP)

Houston, Columbia. Over.

Bruce McCandless (CAPCOM)

Columbia, this is Houston. Go ahead.

Michael Collins (CMP)

Roger, Bruce. When you get a few minutes could you give me some words on tomorrow's activities—when they're going to start?

Bruce McCandless (CAPCOM)

Columbia, Columbia, this is Houston. Over.

Bruce McCandless (CAPCOM)

Columbia, this is Houston. Over.

Bruce McCandless (CAPCOM)

Roger, Mike. Couple of quick flight plan update here. First off, we'd like to get an O2 fuel cell purge at time 113 30. You—Are you copying? Over.

Bruce McCandless (CAPCOM)

Secondly, we will return to the nominal timeline with your scheduled wakeup of 121 hours and 12 minutes. We sort of slipped by lithium hydroxide canister change number 9 during the EVA and EVA PREP. We'd like you to accomplish that now. The COMM for sleep will be the normal lunar COMM configuration, the RCS configuration. We're requesting you use quads Alfa and Bravo. A DAP data load for R2 should be 01111. Readback. Over.

Michael Collins (CMP)

Roger. Oxygen fuel cell purge at 113 30. Return to the nominal timeline at 121 hours wakeup. Lithium hydroxide change number 9 right now. Normal lunar COMM sleep configuration, I'm in that now. On the RCS, I understood before you wanted to load the DAP register 2 011000 which made sense, and then later to pitch only on quad A, enable all on quad B, and C and D off. But you don't want to do that any more, huh?

Bruce McCandless (CAPCOM)

Columbia. This is Houston. On your DAP load in R2, we're requesting a 0 an four 1's, that is, 01111. Over

Michael Collins (CMP)

Load's going in right now.

Bruce McCandless (CAPCOM)

Roger. And you'll be enabling quads Alfa and Bravo on the AUTO RCS select switches. Disable Charlie and Delta.

Bruce McCandless (CAPCOM)

And we have a little less than 2 minutes to LOS. If you're still up, AOS next time around will be 114 04. Over.

Bruce McCandless (CAPCOM)

And, Columbia, if it's agreeable with you, we'd like you to stay awake until we have one successful reacquisition on the high gain antenna. And I guess you can plan on turning in shortly after AOS this next pass. Over.

Bruce McCandless (CAPCOM)

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

Bruce McCandless (CAPCOM)

Roger. Reading you loud and clear. Just wanted to make sure we still had COMM.

Neil Armstrong (CDR)

Roger. We just finished up—we're just finishing up our eat period. Be ready to go back into PREP for DEPRESS.

Bruce McCandless (CAPCOM)

Tranquility Base, this is Houston. Over.

Neil Armstrong (CDR)

Roger. Go ahead, Houston.

Bruce McCandless (CAPCOM)

Roger. On your next depressurization, it's acceptable to use the overhead hatch dump valve in addition to or instead of the forward hatch dump valve to speed up the depressurization of the cabin. I have a T13 update for you, and if you could, sometime here, give us P00 and DATA; we'll uplink you a new CSM state vector. Over.

Bruce McCandless (CAPCOM)

Roger. Your T13 time is 124 22 02. Over.

Bruce McCandless (CAPCOM)

That's affirmative. That is 02. And do you have a time estimate for us until you're ready to start cabin DEPRESS? Over.

Bruce McCandless (CAPCOM)

Tranquility Base, this is Houston. Uplink complete. The computer's yours, and you can go out of DATA.

Neil Armstrong (CDR)

Go ahead. Tranquility Base, here.

Bruce McCandless (CAPCOM)

Roger. Just want to let you guys know that since you're an hour and a half over your timeline and we're all taking a day off tomorrow, we're going to leave you. See you later.

Neil Armstrong (CDR)

I don't blame you a bit.

Bruce McCandless (CAPCOM)

That's a real great day, guys. I really enjoyed it.

Neil Armstrong (CDR)

Thank you. You couldn't have enjoyed it as much as we did.

Bruce McCandless (CAPCOM)

Sure wish you'd hurry up and get that trash out out of there, though.

Neil Armstrong (CDR)

Yes. We're just about to do it.

Bruce McCandless (CAPCOM)

Tranquility Base, this is Houston. We show the suit relief valve still in the AUTO position. It should be closed. Over.

Bruce McCandless (CAPCOM)

Columbia, this is Houston. Over.

Michael Collins (CMP)

Houston, Columbia. Go ahead.

Bruce McCandless (CAPCOM)

Roger. We've successfully reacquired high gain antenna. Unless you have some other traffic with us, I guess we'll bid you a good night and let you get some sleep, Mike. Over.

Bruce McCandless (CAPCOM)

And we're going to power down the voice subcarrier part of our uplink to you in order that we don't disturb you while we're talking to Tranquility Base. If you need us, just give us a call, and we can respond with a time lag of about a minute to a minute and a half in setting reconfigured. Over.

Michael Collins (CMP)

Good night, Bruce. Thanks a lot.

Bruce McCandless (CAPCOM)

Columbia, Columbia, this is Houston. We'd like you to ENABLE the thrusters in Bravo 1 and Bravo 2, AUTO RCS SELECT. Over.

Michael Collins (CMP)

Okay. Bravo 1 and Bravo 2 ENABLE.

Bruce McCandless (CAPCOM)

Tranquility, this is Houston. For a reference, which dump valve are you using? Over.

Neil Armstrong (CDR)

We used the forward dump valve until about 2 psi, and we're using the overhead now.

Neil Armstrong (CDR)

They're both—they're both open now.

Neil Armstrong (CDR)

Houston, Tranquility Base. REPRESS complete.

Bruce McCandless (CAPCOM)

Roger, Tranquility. We observed your equipment jettison on the TV, and the passive seismic experiment recorded shocks when each PLSS hit the surface. Over.

Neil Armstrong (CDR)

You can't get away with anything anymore, can you?

Bruce McCandless (CAPCOM)

Tranquility Base, this is Houston. Over.

Bruce McCandless (CAPCOM)

Roger. When you get back into your surface checklist and come over to the COMM reconfiguration on page Surface 45, we'd like you to enable the ranging feature on your S band. That is, when you come down to S band configuration, instead of CAUTION and WARNING ELECTRONICS, ENABLE TV, we'd like you to go into the RANGE position and leave it there for as long as you conveniently can until you get ready to commence your rest period; and we'll try to get a little more ranging data on you. Over.

Bruce McCandless (CAPCOM)

And of course, when you get ready to turn in, go back into caution and warning, ENABLE, and we'd like to say from all of us down here in Houston and really from all of us in all the countries and in the entire world, we think that you've done a magnificent job up there today. Over.

Neil Armstrong (CDR)

Thank you very much.

Bruce McCandless (CAPCOM)

Yes, indeed. Get some rest there and have at it tomorrow.

Buzz Aldrin (LMP)

Houston, Tranquility. Did you all come up with any other solution that we might try to the mission timer problem? Over.

Bruce McCandless (CAPCOM)

Stand by, Tranquility. We'll be back with you in just a minute.

Buzz Aldrin (LMP)

And, Houston, Tranquility. Have you had enough TV for today?

Bruce McCandless (CAPCOM)

Tranquility, this is Houston. Yes, indeed. It's been a mighty fine presentation there.

Buzz Aldrin (LMP)

Okay. Signing off. See you again tomorrow.

Bruce McCandless (CAPCOM)

Columbia, Columbia, this is Houston. Over.
