Okay. I read back plus 00.692, plus 11713, and minus 00144. And you have a grid square for me?
-
Bruce McCandless (CAPCOM)
-
Columbia. This is Houston. Grid coordinates: Kilo 0.9, 6.3, on LAM 2. Over.
-
Michael Collins (CMP)
-
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.
-
Bruce McCandless (CAPCOM)
-
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.
-
Bruce McCandless (CAPCOM)
-
Roger. And we've had to disable the one way MSFN relay owing to a ground site reconfiguration down here. Over.
-
Bruce McCandless (CAPCOM)
-
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.
-
Michael Collins (CMP)
-
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.
-
Bruce McCandless (CAPCOM)
-
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.
-
Bruce McCandless (CAPCOM)
-
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.
-
Michael Collins (CMP)
-
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 …
-
Bruce McCandless (CAPCOM)
-
Roger. When you all have a free moment, I have your T8 through T12 block data. Over.

Bruce McCandless (CAPCOM)

Roger, Tranquility. T8, 114 30 57; T9, 116 29 10; T10, 118 27 23; T11, 120 25 36; T12, 122 23 49. Readback. Over.
-
Buzz Aldrin (LMP)
-
Roger. T8, 114 30 57; T9, 116 29 10; T10, 118 27 23; T11, 120 25 36; T12, 122 23 49. Over.
-
Michael Collins (CMP)
-
I say again, I am maneuvering to the P52 attitude, and do you want a crew status report?
-
Neil Armstrong (CDR)
-
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.
-
Bruce McCandless (CAPCOM)
-
This is Houston. We copy. And, for your information, the new LM weight after jettison of equipment including lithium hydroxide canister is 10837. Over.
-
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.
-
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.

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