Spacelog Apollo 11

Okay.

Okay. I read back plus 00.692, plus 11713, and minus 00144. And you have a grid square for me?

Roger. Standby.

Columbia. This is Houston. Grid coordinates: Kilo 0.9, 6.3, on LAM 2. Over.

Kilo 0.9 and 6.3. Thank you. One of these grid squares is about as much as you can scan on a single pass.

Roger.

And for your information, Columbia, you're approaching the VHF line of site COMM limit with Tranquility Base. LOS will be at 38 minutes plus 25 seconds. Over.

Roger.

Roger. And we've had to disable the one way MSFN relay owing to a ground site reconfiguration down here. Over.

Houston, Columbia. …

This is Houston. Go ahead. Over.

Roger. I can't see them.

Roger. I guess that takes care of the news for today, Mike.

All right. Roger.

You might be interested in knowing, Mike, that we have gotten reflections back from the laser reflector ray they deployed, and we may be able to get some information out of that a little later.

Roger. I need a very precise position, because I can only do a decent job of scanning maybe one of those grid squares at a time. The area that we've been sweeping covers 10's and 20's and 30's of them.

Roger. We understand. This is intended to be your last P22. We don't want to use up too much fuel in this effort. Over.

Roger. How's the fuel coming?

Roger. There's no problem fuel wise. It's just that there seems to be a limit to the number of P22's and the number of grid squares you can search over.

Roger. Well, I'll continue this maneuver then to roll 82, pitch 218, yaw zero, if that's okay with you, and do a P52 in that attitude. And that'll be a sleep …

Roger. That's fine with us. And P52 in that attitude.

Tranquility Base, this is Houston. Over.

Houston, Tranquility Base. Go ahead.

Roger. When you all have a free moment, I have your T8 through T12 block data. Over.

Roger. Stand by one.

Houston, Tranquility Base. Ready to copy.

Roger, Tranquility. T8, 114 30 57; T9, 116 29 10; T10, 118 27 23; T11, 120 25 36; T12, 122 23 49. Readback. Over.

Roger. T8, 114 30 57; T9, 116 29 10; T10, 118 27 23; T11, 120 25 36; T12, 122 23 49. Over.

Readback correct. Houston out.

Houston. Columbia.

Houston, Columbia on high gain.

Houston, Tranquility Base.

Columbia. Columbia, this is Houston. Over.

Columbia in the high gain.

Roger. Reading you loud and clear on the high gain, Columbia.

Roger. Going to P52 attitude. You want a crew status report?

Say again, Columbia?

I say again, I am maneuvering to the P52 attitude, and do you want a crew status report?

Roger. And go ahead with your crew status report.

Roger. No medication. Radiation 100.16.

Houston. We copy.

Houston, Tranquility Base.

Go ahead, Tranquility.

Roger. The weight of the RCU was 12 ounces. That was by itself without the bag, and the weight of the water from the CDR's PLSS was 12 1/2 ounces. That's reading zero with the bag on.

This is Houston. We copy. And, for your information, the new LM weight after jettison of equipment including lithium hydroxide canister is 10837. Over.

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.

Fifteen minutes, maybe?
