Spacelog Apollo 11

11, Houston. We have a recommended configuration for your CRYO switches to even up the load between oxygen tanks 1 and 2. Over.

…

Okay. You're coming in very weakly there. We're recommending O₂ tank 1 heater OFF, O₂ tank 2 heater to AUTO, O₂ tanks 1 and 2 fans both OFF, H₂ tank 1 heaters to AUTO, and H₂ tank 1 heaters to AUTO, and H₂ tank 2 heaters to OFF. Over.

Roger. We have that except the last one was H₂ fans to OFF. Is that affirmative?

We have—The configuration we have now is—Hydrogen heaters: we got 1 AUTO, 2 OFF. Oxygen heaters: 1 OFF, 2 AUTO. And we have all the fans OFF.

This is Houston. Roger. We concur. Out.

11, this is Houston. We've completed the trunnion zero bias setting. You can retrieve the computer and go to BLOCK.

11, this is Houston. With this maneuvering to observe the slingshot, I guess we missed copying your LM/CM DELTA-P reading. Over.

Stand by. We'll give you a …

Roger.

Right now, reading 0.2, Bruce.

Roger. 0.2.

Okay, Mike. And could you verify that your waste compartment valve is in VENT, there?

Roger. Waste compartment valve has been in VENT for—oh, I guess, 45 minutes or so.

Roger. We copy.

If we're late in answering you, it's because we're munching sandwiches.

Roger. I wish I could do the same here.

No. Don't leave the console!

Don't worry. I won't.

FLIGHT doesn't like it.

How is FLIGHT today?

Houston, 11.

Go ahead, 11.

Down in the control center you might want to join us in wishing Dr. George Mueller a happy birthday.

Roger. We are standing by for your birthday greetings.

I think today is also the birthday of California, and I believe they are 200 years old, and we send them a happy birthday. And I think it's Dr. Mueller's birthday, also, and I don't think he is that old.

Roger. We copy. I'm looking back in the viewing room right now. I don't see him back there.

He may not be back from the Cape yet.

Roger. I believe Dr. Mueller is on his way back from the Cape. We will relay his greetings for you.

11, this is Houston. Over.

Go ahead, Houston.

Roger. At your convenience, we would like to get a waste-water dump to 5 percent remaining. After completion of this one, the next wastewater dump will be at about GET equal to 25 hours. Over.

Coming on right now.

Houston, Apollo 11. Did you copy our torquing angles?

Roger. Leave them on there probably a second, please.

Will do.

11, this is Houston. We copy the angles, but stand by before you go ahead and use them. Over.

Standing by.

11, Houston. We request that you read P52, and if the angles come out the same magnitude, go ahead and incorporate them. Over.

Okay. We'll do that.

They look a little large right now.

Yes. Roll—roll locks a little large, especially, there.

Roger.

We're showing a waste-water quantity of about 13 percent on TM now, 11. Over.

Roger. It's off, now

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.

Go ahead, 11. Over.

Roger. You're looking at our DELTA-R DELTA-V. It looks like DELTA-R is pretty large, there. We wanted to talk to you about it before we incorporate it.

Stand by, Mike. We don't have anything on our downlink here, I don't think, on the DSKY. Stand by.
