Spacelog Apollo 11

Roger, 11. If you'll break out your alternate and contingency checklist for the CSM, we got an update to some of the erasable loads on page F2-20, Over.

Okay. Be getting that out, and you can give us the attitude for TV.

Roger, 11. Your TV attitude will be roll 261, pitch 090, yaw 000. High gain angle: pitch plus 28, yaw 271. That puts the left-hand window pointed at the Earth. We recommend exiting PTC with your updated procedure in the checklist. Over.

Roger. We copy roll 21—61, pitch 090, yaw 000, high gain pitch plus 28, yaw 271. And we'll like this with the DELTA-V that we have in the book. Over.

That's affirmative.

Charlie, Apollo 11. I have a couple of questions on stopping the PTC. It seems to me the easiest way to stop it would be—we're essentially, of course, at 0 degrees yaw and closing up to 90 degrees pitch, so it's just a question of stopping at 260 roll, roughly, and—How about for a procedure going MANUAL ATTITUDE, three to RATE COMMAND and then, seeing as how our deadband has already collapsed, I'll turn on the panel 8 RCS thrusters, at which time it should stop at whatever attitude it finds itself in. And if I do all of that as it comes up on 261 degrees roll, we should stop right there. Is that sufficient?

Sounds like it might save a little gas.

Houston, Apollo 11. What page do you want in that revision? Over.

Roger, 11. If you'll turn to page F2-20. Over.

Okay, Tim -

Roger, 11. Under column A on page F2-20, line 5, line 05, the new data is 01042; line 07, the new data is 00256. Skipping down to line 11, 00070; line 12 is 00042; line 13 is 77730. In column Bravo, lines 3, 4, and 5, which are blank, should be all zeros for line 3; line 4 is 20017; line 5 20616. Over.

Roger. Page F2-20, column Alfa: 05, 01042; 07, 00256; 11, I'll say again. 11, 00070; 12, 00042; 13, 77730. Column Bravo: 03, 00000; 04, 20017; 05, 20616. Over.

Roger. Good readback, Buzz. And stand by, Mike, on the coming-out-of-the-PTC recommendation. Over.

Okay. Fine.

Hello, Apollo 11. Houston with some more words on exiting PTC. Over.

Go ahead, Charlie.

Roger. Mike, when you were playing with the P37 a while ago and we collapsed the deadband back down, the DAP assumed that the deadband was centered around the new attitude that we happened to be at, at that time. Since then, we've drifted out a couple of degrees in both pitch and yaw from that attitude such that if we did the procedure as we called it up to you of going ACCEL COMMAND, turning on all of the AUTO RCS SELECT switches and then RATE COMMAND, it would attempt to fly back to the pitch and yaw attitude that it had when the deadband collapsed. We can prevent that by—just immediately prior to going to RATE COMMAND on the MANUAL ATTITUDE switches, if you cycle the SPACECRAFT CONTROL switch to SCS, then back to CMC. Over.

Sounds like a winner.

Okay.

I'm not going to let these LM guys play with my DSKY anymore.

You sound like you'd better protect it. It looks like just about anything that you do with that DSKY is going to collapse that deadband back down.

Charlie, we just STABED to 261 degrees roll, and it looks like whoever figured it out did a good Job. It's right there, dab-smack in the middle of window number 1.

Looks like Houston's still got a little smog over it, Charlie.

We've got a constant overcast here in the room. We'll be right there. Stand by.

Of course, a little cloud from up here probably covers 8 or 10 states.

11, Houston. Some of our guys just came in from outside and said it's pretty clear over the center here. It's cleared up completely. All the storms have moved on.

Oh, yes, Charlie. I can see it through the sextant now, and I can see the coastline is clear. Those clouds are just inland a few miles.

Okay. We copy.

Looks like the southeast part of the country is all socked in.

California looks nice. The San Joaquin Valley shows up as a real dark spot with a lighter brown on either side of it. You can't tell that it's green. It looks just sort of dark gray or maybe even real dark blue.

How does the Mojave look? Is it clear?

Yes. As usual.

Roger. The—around -

It looks like there's some clouds just to the west of the Sierras, northeast of Bakersfield a little bit; and crossing over into the Mojave from Bakersfield looks clear; and then as you get on further to the southeast of there, there's a few clouds.

Roger, 11. Can you pick out Edwards in the sextant? Over.

I can see a 104 taxiing out for takeoff on the runway.

Hey, man. That's super.

These dang bastards almost always have a 104 taxiing out for takeoff.

11, Houston. Could you pick out anything around Edwards, a dry lake or anything? Over.

Negative, Charlie. I just—I don't have that resolution. But to give you some idea, I can—on the lower Texas coast, I can see—knowing what I'm looking for, I can see Padre Island. I can just barely make out the fact that there's a thin spit of land and then there's a little dark zone which is the Laguna Madre between it and the mainland.
