Spacelog Apollo 11

Roger.

How's the Black Team today? All primed and raring to go?

You bet you there, Mike.

Columbia, Houston. About 3 minutes to LOS, and I have your consumables update.

Ready to copy.

Roger. At 123 plus 00, RCS total minus 7 percent, Alfa minus 12 percent, Bravo plus 4.5, Charlie minus 7, Delta minus 6.5. Your hydrogen total minus 1.4 pounds, oxygen—oxygen plus 1.7. Over.

Whoever figured those hydrogens and oxygens out a couple of days ago must have known what he was doing.

Okay. I think I read that oxygen—it's a plus 17 pounds.

Roger. Still close.

Roger.

Eagle and Columbia, this is the backup crew. Our congratulations for yesterday's performance, and our prayers are with you for the rendezvous. Over.

Thank you, Jim.

Thank you, Jim.

Glad to have all you big room full of people looking over our shoulder.

Tranquility, Houston. Roger. Very fine description.

I suspect this boulder field may have some of its origin with this large sharp edged rocky rim crater that we passed over at final descent. Now yesterday I said that was about the size of a football field, and I have to admit it was a little—little hard to measure coming in. But I thought that it might just fit in the Astrodome as we came by it. And the rocks in the vicinity of the—of this rocky rim crater are much larger than these in this area. Some are 10 feet or so and perhaps bigger, and they are very thickly populated out to about one crater diameter beyond the crater rim. Beyond that, there is some diminishing, and even out in this area the blocks seem to run out in rows with irregular patterns, and then there are paths between them where there are considerably less surface evidence of hard rocks. Over.

Tranquility Base, Houston. We copy. Thank you very much.

And, Tranquility Base, we're through with the ranging. You can take your S band function switch to OFF RESET.

Roger.

And, Tranquility, I have a LM consumables update for you.

Roger. Ready to copy.

Okay. At 123 plus 00, RCS Alfa 78—78 percent PQMD, Bravo is 76 percent PQMD, descent O₂ is 62 percent—62 percent. Descent ampere hours are 590, 590 remaining, ascent ampere hours are 574, 574 remaining. Over.

Roger. Copy. Sounds very good. Thank you.

Tranquility Base, Houston.

Go ahead, Houston.

Roger. For your P57 …, we did a little looking around, and it looks like Sirius and Rigel out at detent 6 would be real good on that. The Sun angle on Sirius is about 43 degrees, and on Rigel, it's about 55 degrees. Over.

Roger, Houston. The only trouble is that the Sun is in number 5, the closed one. And it appears to also be close enough to detent 6 to shine on the far side of the cone. And it completely obscures detent 6. I'm—unable to use that at all.

Okay. We understand it now, and thank you.

Tranquility, Houston. For your information, the circuitry looks real fine on that ascent engine arm circuit breaker.

Roger. I don't think I could get it out now if I wanted to.

Roger. We copy.

And it looks like in detent 6 I can pick up Venus right at the fringe, but I can't get anything else.

Roger.

And by the way, Houston, our EVA antenna did retract.

Roger. Mighty fine. Thank you.

Tranquility, Houston.

Roger. Go ahead.

Roger. It looks like you're going to have to reposition the radar here. We suggest you may want to start your TIG minus 45 minute—that point in the checklist at about TIG minus 50. Over.

Roger. Why do you think I need to move the radar?

Well, we thought that you probably wouldn't be able to get the star there.

On the rear detent, the radar can be pointing plus X, and I'm—I'll be using right rear. That's okay.

Roger. That's fine then.

Tranquility Base, Houston. I have one more late checklist change there on the rendezvous radar position for lift off. Over. From page Surface 57.

Roger. Go ahead.

Okay. On Surface 57 there on your VERB 21 NOUN 73 trunnion, leave it 180; the shaft we'd like 335. Over.

Roger. Understand. Shaft 335.

Roger. And if the steerable doesn't quite hack it on lift off, looks like the forward OMNI is good for about 30 to 60 seconds after lift off. And then the aft OMNI antenna is good for the rest of the ascent. Over.

Roger. Copy.

Houston, we've got two angles here at 3 minutes in ascent. Would you confirm those? Pitch 134 and yaw minus 32. Over.

Tranquility Base, Houston.

Go ahead.

Roger. Eagle's looking real fine to us down here. We have a fairly high confidence that we know the position of the LM. However, it is possible that we may have a planes change, but the—In the worst case, it would be up to 30 feet per second. And, of course, we don't expect that at all.

Okay.

Houston, Tranquility Base. Since we've still got plenty of time I think I'll go ahead and recycle on this 604.

Tranquility. Roger. That's okay with us, and we assume that the primary canister is still aboard. Is this correct?

We have one primary canister on board and one secondary. The other primary is—out in front of the Z—plus—Z pad. Over.

Roger. We copy. Thank you.

Ready for the blue bag —

The PGNS looks consistent today.

Houston, did you copy NOUN 05, and are you looking at 93? Over.

Tranquility Base. It's beautiful.

Okay. We'll proceed.

Roger.

I know where the star is; I'm not sure the PGNS knows where gravity is.

Houston, these are your angles, not ours.

Roger, Tranquility.

Stand by for some change or modification in the angles.

Tranquility Base, Houston. Recommend 334, and that should just keep it out of the limit.

Houston, Columbia on OMNI D Delta. Over.

Columbia, Houston. Roger. Loud and clear. And if you would like to take it down, we have the latest position of Tranquility Base. Over.

Go ahead.

Roger. It's just west—at west crater, Juliett 0.5, 7.7. Over.

Understand that it is just west of the crater Juliett 0.5 and 7.7. Is that correct?

Columbia, Houston. That is correct.

Okay. Thank you, Ron.

Tranquility Base, Houston.

Go ahead.

Roger. Because of the lower load with the rendezvous radar off, we'd like to have battery 5 and 6 on the line now, 1 and 3 off. Over.
