Spacelog Apollo 11

Hello, Apollo 11, Houston. We'd like P00 and ACCEPT. We have a DELTA-H update for you. Over.

All right, Charlie. Stand by one.

Houston, Apollo 11. P00 and ACCEPT.

Apollo 11, Houston. We got the load in. The computer's yours. Over.

Hello, Apollo 11. Houston. We'd like for you to stir up the CRYO's now. Over.

Houston, Apollo 11. We're completed in the LM. We're closing up the hatches and the probe and drogue back in.

Hello, Apollo 11. Houston. We're standing by to watch your startup on the PTC at any time. You can start off at the VERB 49. Over.

Wilco. We're just finishing up the probe and about to close up the hatch here. We're going to be a couple of minutes late, probably, getting started in the PTC.

Hello, Apollo 11. Houston. Mike, there's no wait required. Where rates are steady, you can proceed on. Over.

I'm doing it, Charlie.

Roger.

The tunnel's all taken care of, the drogue, probe, and hatch all back.

Hello, Apollo 11. Houston. We have some new additions to your alternate contingency checklist if you would break that out. Over.

Stand by.

Okay, Houston. 11's ready to copy.

Roger, 11. If you'll turn to page F2-22. Over

Okay. I have F2-22.

Roger, Neil. Under column 1—that's column Lima, line 06. The new data is 00001. Line 07, the new data is 02134. Over.

Okay. I have in F2-22, column Lima, item 6, 00001; item 7, 02134.

Roger. That's correct. Thank you much. Out.

11, Houston. For your information, those two entries are an update to your DELTA-H that we have already uplinked into the CMC. Over.

Roger. Thank you.

What was I marking on, Charlie? About an 18-kilometer line, or what?

We—Our update puts you to—the DELTA-H to 35 kilometers, Mike. Over.

Hello, Apollo 11. Houston. We've got some switch positions for you for the high gain. Over.

Okay. Go ahead.

Roger, Buzz. Select Bravo, OMNI, HIGH-GAIN TRACK to MANUAL; BEAM, WIDE. Over.

Okay. Bravo, OMNI; TRACK, MANUAL; and BEAM, WIDE.

Roger. And your high-gain angles are minus 50 on the pitch, 270 on the yaw. Over.

Hello, Apollo 11. Houston. We have some updates and some things we'd like to talk to you about, if you aren't in the middle of your meal. If it's convenient anytime for you, we're ready with some updates. Over.

What—What are the updates going to apply to?

Roger. We have a couple of changes on the LM mission rules NO GO for your NO GO card, Neil. One slight change on the APS/DPS fuel and TEMP pressure card, and we have a change to the procedure for the secondary radiator leak check, which is to be formed at—performed at 71 hours tomorrow, and also some indications that we have a couple of landing site obliques stowed in the wrong place. Over.

Okay. Is any of those in the flight plan? The secondary radiator, for example?

That's affirmative. The secondary radiator leak check is called out in the flight plan at 71 20. That procedure is listed in your launch operations book on page 2 9, L2 9. We'd like to change that procedure. Over.

Okay. Stand by.

Charlie, on the secondary leak check, just read it verbatim like you want, and I'll copy directly into the flight plan and not fool around with the checklist.

Roger. That's fine. If you're ready to copy, stand by.

Ready to copy on the leak check.

Roger. It's monitor secondary accumulator quantity. Step 2 is secondary glycol to radiator valve, NORMAL for 30 seconds, then BYPASS. If no decrease in secondary accumulator quantity—Are you with me?

Yes, I'm with you.

Roger. Stan is concerned that our present procedure as shown in the checklist does not really flow glycol through the radiator, and it—They want to verify that we do not have a plugged secondary radiator. Over.

Okay. They have any abnormal indications in that system, so far?

Negative. This is the procedure that they came up with. It's just a check, Mike. Everything's looking great to us. Over.

Okay. Fine.

Charlie, we'll get back with you on these other changes in a few minutes. Okay?

11, Houston. We're wondering who's on horn.

Say again, Houston?

We just had a little music there.

We'll keep you entertained.

Roger. That was good. You can keep it coming down, 11.

Okay.

Because it's a special occasion today, Houston. This is the third anniversary of Gemini 10.

Roger. Happy anniversary.

Houston, Apollo 11. Ready to copy your update.

Roger. Stand by.

Okay, Buzz. The first item is that we have indications that your landing site obliques are not in the proper position. If you'll check, we think that the intermediate scale landing site oblique is stowed in the CSM lunar landmark book. We think that the large scale landing site oblique is stowed in the back of the LM lunar surface map book. Over.

I think I heard you Charlie, but I'm not sure that I understand.

Roger. According to our stowage list the—the landing site oblique should be in the transfer bag. In—But in the backup set of data, the intermediate scale oblique is in the CSM lunar landmark book, and the large scale oblique is in the back of the LM lunar surface map book; and that's the reason we think that they might be not where you think they are. Over.

Okay. We've got three obliques. The last one is one I asked for recently. It's just a blow up of the second one. The first one is one that's got dotted lines on it, indicating horizon view and 50-degree LPD; and all three of those are in the transfer book. Over.

Roger. Fine. We were wrong in our—in our backup set. We had those out of place. Looks like the onboard data's good. We just wanted to let you check on that one. We have an update on the APS/DPS fuel card that you place on the panel. It's a typo error. If you'll break out that little card, we've got the—correct that typo error. Over.

Stand by.

Okay. I got it.

Roger, Buzz. Under the DPS column on the pressure side, you go down to the fourth item, says pressure greater than 150 PTCA should be greater than 65 percent. Over.

Okay. That's greater than 1.8 but less than 65 and greater than 150 for greater than 65.

That's affirmative. Out.

And we have three items on the mission rules NO-GO card, if you're ready to copy those. Over.

Okay. I've got the mission rules NO-GO.

Roger, Buzz. First entry's on the EPS under AC bus A. The line extends all the way to high gate. Actually, the line should read—at DOI it would be NO-GO AC bus A. After that the NO-GO would be both buses. So if you will just pencil in both buses from PDI through high gate, it'll be correct for that line. Over.

Okay. I've got that: AC bus A for DOI and both buses NO-GO for PDI on.

That's affirmative up until high gate. You can stop at the line in front of the column “5 minutes to low gate”. Now the next line is under the G&C PGNS, pitch and roll GDA's. You can scratch that line completely. Over.

Roger. Got it.

Okay, Buzz. Last entry is down under RCS, and it's a typo error under the three—in the line “three axis attitude control”. If you proceed to the right at PDI plus 05, you'll see one axis. The line goes all the way to low gate to touchdown. That's incorrect. The line should stop under “5 minutes to low gate”. Over.

Okay. We're stopping that at “5 minutes to low gate”.

This is Apollo 11. Radio check.

Roger. Reading you five by. How me? Over.

Okay. Loud and clear. You cut out when you were talking about the platform—something about 52 hours and after that, we never heard you again.

Roger. Guess we were changing antennas. Stand by. That's affirmative, 11. We were swapping antennas on you down here. Basically the word is that we have a real good platform, very small drift on the GYRO's, and very small drift in the PIPA's. Over.

Roger. Thank you. And I would like to have a few words of clarification if you will give them to me on the RCS … what that change of pitch may mean.

Copy. A few words of clarification on the RCS? Oh. Roger. The update there, Neil, you are speaking of about the one axis down to 5 minutes of low gate?

Yes. That's right. I'm not quite sure what that … means beyond 5 minutes.

Stand by. I'll make sure I got my story straight with Control. Stand by.

Okay.

11, Houston. On the RCS, what we are saying is that if we lose control about one axis prior to low gate, we would recommend an abort. This would require a—a loss of—of two distinct jets which is not very probable, but that is what we are recommending. After low gate we would continue on. We would recommend that we continue on to attempt a landing. Over.

Roger. I think I …

Roger.

Charlie, did you say you had some updates for me from the lunar surface book?
