Spacelog Apollo 11

Okay.

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.

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

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

Roger. Coming open.

Roger. Out.

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.

Roger. We copy. Stand by please.

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.

Roger. Copy.

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

Roger. 11014 for the CDR.

Roger. LMP reads 09018. Over.

Houston, Columbia. Over.

Columbia, this is Houston. Go ahead.

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

Columbia, Columbia, this is Houston. Over.

Columbia, this is Houston. Over.

Go ahead.

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.

Roger. And copy.

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.

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?

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

Okay.

And you —

Load's going in right now.

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

All right.

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.

Roger.

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.

Okay.

Roger. Out.

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

Go ahead. Houston.

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

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

Tranquility Base, this is Houston. Over.

Roger. Go ahead, Houston.

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.

All right.

You've got the DSKY.

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

Roger. It's T13, 124 22—is that 02? Over.

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

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

Tranquility Base, Houston.

Go ahead. Tranquility Base, here.

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.

I don't blame you a bit.

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

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

Roger.

It was great.

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

Yes. We're just about to do it.

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

Columbia, this is Houston. Over.

Houston, Columbia. Go ahead.

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.

Okay. Sounds fine.

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.

Okay. Thank you.

Roger. And good night.

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

Okay. Bravo 1 and Bravo 2 ENABLE.

Roger. Out.

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

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

Roger. Out.

Houston, Tranquility Base. REPRESS complete.

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

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

Tranquility Base, this is Houston. Over.

Go ahead, Houston.

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.

Roger. Copy.

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.

Thank you very much.

It's been a long day.

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

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

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

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

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

Okay. Signing off. See you again tomorrow.

Roger.

Columbia, Columbia, this is Houston. Over.

Go ahead, Houston.
