Spacelog Apollo 11

…

It's getting appreciably larger now. It's looking more like the world.

Roger. I'm looking at the right side of the screen this time.

How's everything going on the—Say again, Charlie?

Oh, just—I -I'll never hear the last of that one about that Earth/Moon business during the TV there, and I was just saying that I was looking at the right side of the board here, so you are going towards the Earth. What are—What were you going to say, Mike?

You'll have—You'll have fun at the press conference after this shift then, won't you?

It's 2:30. Everybody will be asleep. I going to sneak off through the back way.

Okay. I was just wondering how everything is going at the home front. All the wives and kids in one piece?

Roger. Sure are. Everything's doing fine. All the gals are having a little party tonight, as far as I know.

Apollo 11, Houston. I was just reading some of the transcripts of earlier today about this earlier PTC that we attempted, and when you keyed into VERB 24 and did the two ENTER's, it took off on you. I think we got a story on that, if you'd like to listen to why it had such a high rate, Mike. Over.

Yes. I'm all ears.

Okay. I think it would be better if you got your checklist out on 97, and we could walk you through it, and that way I could probably get the story straight. Over.

Okay. I got it.

Okay. Mike, what happened is—you know, you were sitting there monitoring VERB 16, NOUN 20, and at step 7 you went into VERB 24, NOUN 01, and keyed in the address and then INFORMATION INFORMATION; and on the final ENTER of that 35400 ENTER, right after that, it—that then put you back into the 16, NOUN 20. Then when you did the VERB 24, ENTER, you were really entering the information in the actual CDU; and when you got the two entries in, in register 1 and 2, it was an—it was an instantaneous change in the actual CDU, and the CM DAP looked at that and saw—saw what it thought it had. My—my gosh, I got a 600 degree per second rate. And it turns on the jets to try to take that rate out. And the rate filters that it's looking at—it—well, the rate it's looking at is filtered, so it doesn't really sense the actual rate until the thing is already built up, and then it starts reading the rate filters, and it says, “Well, I really didn't have 600 degrees.” So then it turns it off and tries to slow it down. But until that happens, and it is some time lag, and that's why the rate was building up. The jets were on, and they were going to stay on due to that instantaneous 600—suspected 600 degree per second rate. Over.

Okay. I got you.

Roger.

Man.

Hey, Charlie, are you saying that for a short period of time, he actually loaded NOUN 20 with some value other than was being read by the CDU?

I think I got that, Buzz. That's affirmative. But when he did that second VERB 24, you were—the NOUN was 20, so when he did the 3175 and then a 002 ENTER, what he actually did there was load the first two actual CDU locations, and the computer looked at it—the DAP looked at it as an instantaneous change in the actual CDU. Stand by on your comments. We're switching antennas.

Roger.

— We're very scratchy.

Okay.

11, Houston. We got you back now on the high gain. Did you copy all that, Buzz? Over.

Yes. I think so. I—I thought maybe that NOUN 20 was one of those that you could never load from the DSKY, and that still maybe. Maybe it was loaded just for the short period of time, and then when the counters read the—the gimbal angles, why they changed it back to what they actually are. But in the meantime, the DAP saw this different number. Is that right?

Well, our guidance guy was telling me that you can actually load those ACDU's, the actual CDU's, but we'll—we're checking on that. Over.

Okay.

11, Houston. Buzz, the word from the back room is that you can actually load the NOUN 20, but you should not.

Yes. I got that. Thank you.

Okay. Crew status report. Radiation: CDR 11020, CMP 10022, LMP 09024. No medication.

Roger. Copy.

And, Neil, we got—we'd like your onboard readouts of batteries and RCS. Over.

Okay.

Okay, Charlie. Ready to copy?

Roger. Go ahead. Over.

Okay. BATT C, PYRO BATT A, and PYRO BATT B are 37.0. RCS A, 51; B, 63; C, 63; D, 59. Go.
