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. 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.

Fifteen minutes, maybe?
