Spacelog Apollo 11

Houston, Apollo 11. Torquing angles essentially the same, and we're going to go ahead and torque them now.

Roger. We concur.

Okay.

Apollo 11, this is Houston. Could you give us a—an AUTO optics check to a third star or a different star from the one you've been using?

Sure, be glad to. I can go back and do the whole thing and pick different stars.

I don't think there—there's any need to do that. We'd just like to confirm it with a different star, since that roll angle was a little larger than we expected.

Okay.

Apollo 11, Houston. I have a TLI-plus-11-hour PAD when you're ready to copy.

Wait one.

Old star number 30 looks like it is right dab smack in the middle of the sextant.

Houston. Roger. Out.

Ready to copy.

Roger, 11 This is TLI-plus-11-hours. P37 format: 01344 4793, minus 165 04923. Read back. Over.

Roger. 01344 4793, minus 165 04923. Over.

Houston, Apollo 11.

Go ahead, 11.

Roger. Do you have any update for the roll, pitch and yaw angles on the top of page 37 in the flight plan. Or are they still good?

That's for the optics calibration?

Yes, sir.

Yes, indeed. I'll give them to you in just a second here.

Roger, 11. For the optics calibration I've got 346.5 for roll, 345.0 for pitch, and 007.8 for yaw. The pen-and-ink attitude corrections in your book for P23 are good. Over.

Okay. Thank you.

And we're going to hand over to Hawaii in about 5 or 6 seconds, here. We'll have a momentary COMM dropout.

Hello, Apollo 11. Houston. Be advised your friendly White Team has come on for its first shift, and if we can be of service, don't hesitate to call.

Thank you very much. And we're about to take our marks, Charlie, on this P23 optics CAL. I've got it in the sextant now, and I'm about to split the image and Mark.

Hello, Apollo 11. Houston. We have scrubbed the midcourse 1. Over.

Roger. Understand you've scrubbed midcourse 1.

Hello, Apollo 11. Houston. We see your middle gimbal angle getting pretty big. Over.

Well, it was, Charlie, but in going from one AUTO maneuver to another, we took over control and have gone around gimbal lock; and we're about to give control back to the DAP.

Hey Charlie.

Houston, Apollo 11.

Go ahead, 11. Over.

Hey, maybe you better call Lou and tell him we might be a little bit late for dinner.

Okay. Sure will. We'd like for you to turn on—the fan on in O₂ tank number 2, Buzz. And, 11, did you—on your optics calibrations, did you proceed or recall the program? Over.

We recalled the program.

Roger.

And O₂ fan number 2 is on.

Roger.

Houston, Apollo 11. I've got a CRYO pressure light and a MASTER ALARM. It's reset.

Roger. We expected that. That's why we had you turn the fan on. We were getting pretty close to the caution and warning limits. We were trying to prevent that.

Houston, Apollo 11.

Roger. We got the downlink now. Over.

Okay.

Hello, Apollo 11. Houston. We'd like you to reject the NOUN 49 stuff on the DSKY right now, Mike, and try it again. Over.

Okay. Will do.

Okay, Houston. Apollo 11. Here's another 49 for you. Are you getting it on the downlink?

Roger. We see it. Stand by.

Hello, Apollo 11. Houston. We recommend you accept the NOUN 49 display on the DSKY now. Over.

Okay. It looks like an awful big one. We noticed that you'd moved star number 2 to the tail end of the listing, and we should be marking first on star 40. Did that have anything to do with it?

Negative. We don't believe so, Apollo 11. We think that this is possibly due to some TLI dispersions, and it's probably satisfactory. So go ahead and accept this. It fits our criteria anyway that if you repeat the mark and you get an equivalent size to go ahead and accept it. And this is an equivalent size error. Over.

Okay. We'll do it.

And 11, Houston. Your state vector in the LM slots are—is good. Over.

Roger. Thank you.

Houston, Apollo 11. If you like this, we'll accept it as well.

Stand by.

Hello, Apollo 11. Houston. We recommend you accept the NOUN 49. Over.

Okay, Charlie. Thank you. We'll do that now.

Thank you.

And we're going to proceed on this one, too, Charlie.

Houston, Apollo 11. Another NOUN 49 for you.

Roger. We copy. Stand by.

Hello, Apollo 11. Houston. We'd like you to recycle and do this one over again. Over.

Houston, Apollo 11.

Go ahead, Apollo 11. Over.

Roger. Why don't you sing out when you think we've done enough battery charging on B.

Hello, Apollo 11. Houston. We'll be charging battery B up until the sleep period. We'll discontinue charging at that time. Also, at about 12 25 in the flight plan, we have battery A charge. That has been deleted. Over.

Roger. Understand. We'll charge until the sleep period on B and delete the battery A charge.

Affirmative.

And, Houston, Apollo 11. These AUTO optics maneuvers or P23's, AUTO maneuvers, don't seem to be going to the substellar point. Can you come up with the roll, pitch, and yaw angle for the substellar point on this star? It's our second star.

Roger. Stand by.

Hello, Apollo 11. Houston. Your angles in the flight plan we feel are still good, 198.6 130.7, 340.0. Just slightly off than those in the flight plan. Over.

Okay. We'll try that.

Charlie, state those three angles one more time. I'd like to confirm them before I maneuver.

Roger. Roll and pitch are slightly off than what's in the flight plan, 11. Roll is now 198.6, pitch is 1307. Over.

Roger. Roll 198.6, pitch 130.7, and yaw 34000.

Houston, Apollo 11. I think the problem here is that that attitude just is not too close to the substellar point. I'm having to maneuver quite a bit; and that's in progress now, so stand by for some marks.

Hello, Apollo 11. Houston. We've run the angles given in the flight plan for the P23 attitude through the machines down here, and they come up the same thing every time. We think everything's going correctly, Mike, and we're wondering if the nonsymmetrical horizon might by giving a problem. Over.

Yes, I'd say—It could be, Charlie. Stand by here. We'll get another mark for you.

Okay.

Houston, Apollo 11. NOUN 49 for you.

Roger. Copy.

Stand by.
