Spacelog Apollo 11

Well, if the systems guys have anything they want chased down, we'll be happy to give you any readings or reports or what have you.

Roger. We'll think about that and see if there aren't some other tests to be usefully performed here.

11, Houston. I'll be turning things over to the Green CAP COMM at this time, and see you on the ground tomorrow.

Okay, Owen. I want to thank you and the whole Purple/Maroon group there for a good job helping Apollo 11.

Thank you, sir.

Thanks from us to all of you. It was really appreciated.

Great job, you guys.

Apollo 11, this is Houston. Over.

Go ahead, Houston. Apollo 11.

11, this is Houston. With reference to your subjective evaluation that it felt cooler in side the spacecraft last night, we reported earlier that we did indeed see a drop of about 3 degrees over the previous night. Looking back, it appears the crew of Apollo 10 reported similar feelings during the translunar and transearth coast phases. We're wondering if you could give us any indication of the relative amounts of free or condensed water in the cabin last night and the night before from which we could infer humidity. Over.

Roger. That might be a little bit difficult to do. We'll take a look at the tunnel now. It does seem as though, between the dirt, we had a little bit more moisture in the tunnel. Of course, the LM hadn't been vented when we did translunar.

Roger. We were more curious about the relative amount of moisture between, say, last night and the night before, both of which would have the LM missing.

There's more moisture in the tunnel now than there has been at any previous time. Subjectively we have been unable to determine any change in—any buildup in humidity. There appears to be no moisture any other place in the spacecraft. For example, the windows are not fogging or—and various other cool spots around the spacecraft—all of them appear to be completely dry.

How are all the “Greens” today, Bruce?

Oh, the Greens are in good shape. The actual Green Team has been here for several hours. We're dogging the watch down here to position Ron for entry. Over.

Roger. Understand. Did Dave Reed get to explain the lunar … at the press conference?

He always used to make me sit at the console through the back side passes, just for training.

Well, the word we have here is—that was because whenever you came back, you had to be retrained.

Houston, Apollo 11. Out of curiosity, on those 70 mm cameras, we figure we exposed around 300 in the LM and around a thousand in the command module; and both cameras—or all the 70 mm cameras worked just fine.

Apollo 11, this is Houston. Over.

Go ahead, Houston.

11, this is Houston. Do you all have “Change Lima” for your entry operations checklist dated July 23? Over.

Dated when?

July 23.

I'm not sure that we hung around long enough to pick that one up.

Okay. If you've got the entry operations checklist handy, then I'll pass it up to you. Over.

How can you make changes after lift off?

You sure you don't mean June?

Negative. It just came up today. Over.

So, you're the first to get to us. Go ahead.

Okay. On page 6 1 of the entry out checklist down toward the bottom after “MAIN DEPLOY pushbutton,” we have three additional steps we'd like you to accomplish. The intent of this is to reduce the oxygen pressure in your manifold and to eliminate the oxygen bleed flow through the potable and waste water tanks during descent. Over.

Okay. We've got 6 1 out. Go ahead.

Okay. Down at the bottom, you've got “10,000 feet MAIN PARACHUTE DEPLOY, MAIN DEPLOY pushbutton, PUSH within 1 second.” And after that step, we'd like you insert “SURGE TANK O₂ valve, OFF; REPRESS PACKAGE valve, OFF; and DIRECT O₂ valve, OPEN.” Do you copy?

Okay. Down at the bottom, after “MAIN DEPLOY pushbutton, PUSH; SURGE TANK O₂, OFF; and REPRESS PACKAGE VALVE, OFF, DIRECT O₂, ON” Over.

Roger. And then down at the very bottom of page 6 2 where you see “DIRECT O₂, OFF VERIFY,” delete that step completely. Over.

Roger.

And for record purposes, this will be “Change Lima.” Over.
