Spacelog Apollo 11

Okay. I read back: monitor secondary accumulator quantity; secondary glycol radiator valve, NORMAL for 30 seconds, then to BYPASS. If no decrease in secondary accumulator quantity, secondary glycol to radiator valve to NORMAL. Secondary coolant loop pump, AC 1 or 2. After 3 minutes, verify glycol secondary discharge pressure 39 to 51 psig. Verify secondary evaporator outlet TEMP has changed. Secondary coolant loop pump, OFF. Secondary glycol radiator valve to BYPASS. And what's the reason for the change, Charlie?

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. At the present time, we do not have any updates for you on the lunar surface book. We are thinking about some and kicking them around, but they're very minor changes. Over.

11, Houston. Did you copy that transmission?

Apollo 11, Houston. We swapped antennas on you again. I say again that we do not have any lunar surface update—book updates at this time. We're considering a few minor ones, but we're still kicking them around the MOCR. Over.

Houston, 11. We have a crew status report for you.

Roger. Go ahead, 11.

Okay. Radiation: CDR 11009, CMP 10010, LMP 09011. No medication.

Roger, 11. We copy for the radiations. And, we're considering—this PTC looks sort of weird to us, so we're considering stopping and starting over again, and we'll be with you in a couple of minutes. Over.

Okay.

Apollo 11, Houston. Would you give us the LM/CM DELTA-P reading? Over.

Hello, Apollo 11. Houston. We switched the antennas on you again. Would you please give us the LM/CM DELTA-P reading? Over.

Hello, Apollo 11. Houston. Over.

Go ahead. 11 here.

Roger. We switched antennas on you, there, moments ago, Neil. Could you please give us the LM/CM DELTA-P reading? Over.

It's less than 0.1.

Roger.

0.15, now, Neil says, Charlie.

Roger. Thank you, Mike. Could you give us some help? This PTC is strange: it's not like anything we've seen before. We were wondering if you have had any events or any odd data that could help us out. Over.

I didn't understand that. Say again.

Roger. We're looking at a—sort of a funny looking PTC. We've already drifted out to 70 degrees in pitch and we're wondering if you all have had any vents or any such thing as that, that could have caused us to pick up these rates to drive us off. Over.

Negative, Charlie. We don't know of anything.

Roger.

Unless it's got something to do with that entry from the position that we want to be in. I don't know.

Roger. When we started off, it looked real fine to us. Now it's drifting off with a funny pattern that we haven't seen previously on a flight. And we're just trying to figure out—I think we'll probably start it over again. We'll be with you momentarily. Over.

Apollo 11, Houston. We hate to say it, but we'd like to terminate this PTC and start over again. We have no assurance that we're going to get it through the sleep period with this funny configuration, or funny pattern. We'd like you to stop it now and go back to pitch 090, yaw 0, and roll—whatever you stop on. Over.

11, Houston. We recommend you disable Bravo and Charlie; select quads Alfa and Delta. Over.

Apollo 11, Houston. Over.

Apollo 11, Houston. Over.

Hello, Apollo 11. Hello, Apollo 11. Over.

… Apollo 11. Go ahead.

Roger. Reading you about one-by. Looks like we picked a super attitude here for PTC stabilization. We're reading you in BACKUP VOICE now. Over.

Roger. We read you loud and clear.

Roger.

Would you like us to pick another antenna?

I think we've got about the best configuration. We've been doing it all from the ground here, 11. We'll just keep it as it is. Over.

Apollo 11, Houston. Would you select COMMAND RESET and OMNI Alfa? Over.

Houston, 11 on OMNI Alfa.

Roger. We read you about three-by now. Over.

Apollo 11, Houston. We is stable; you can start the PTC. Over.
