Spacelog Apollo 11

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.

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.
