Spacelog Apollo 11

Apollo 11, say again. You were cut out. Over.

Roger. Did you say you had some updates for us in the lunar surface book. Over.

Negative. At this time, we do not have any updates for the lunar surface book. We wanted you to have it just in case. Over.

Roger. You were cut out that time.

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.

Houston, Apollo 11. Checklist page F9 7; I've completed step 8, and I'd like to know what you think is ideal timing between step 8, step 9, and step 10 on that page? Over.

Roger. Stand by.

Apollo 11, Houston. We don't see any time constraint. We'd like you to go ahead and set up the wide deadband and then go through step 10 and 11. Over.

Okay. Will do. I don't see any constraint here, Charlie. I was just checking to make sure, because last time, I went from 8 to 9 to 10 to 11 a little bit more swiftly than I'd been doing in the past.

Roger.

Step 11 complete.

Roger. We copy.

Apollo 11, Houston. Would you please select OMNI Bravo? Over.

Roger. Bravo.

Houston, Apollo 11. How do you read on Bravo?

Roger. Reading you five-by.

Same here.

Apollo 11, Houston. Looks like we've got a good PTC going. It's good night from the White Team. Over.

Houston, Apollo 11.

Go ahead, 11. Over.

Do you have any idea where the S IVB is with respect to us?

Apollo 11, Houston. The S IVB is about 6000 nautical miles from you now. Over.

Okay. Thank you.

Houston, Apollo 11. How's the PTC looking?

Stand by.

11, Houston. The PTC looks great to us. Over.

Hey, do you have any idea what happened to the previous one?

We have absolutely no idea. Over.

Okay. Did, it look like it was all right, then just all of a sudden start diverging?

That's negative, Mike. If you'll look at the plot, which we'll save for you and let you see it postflight, it started off immediately on the first REV and just spiraled out to about—oh 20 to—20 degrees in pitch, and then it seemed to be setting up a spiral around an offset pitch point of about 20 degrees off from 90 degrees; but we didn't want to take a chance that it would become stable at that point. We thought it might diverge, and so we called you and started over again. Over.

Okay, no complaints. I was just curious as to what had happened.

Houston, Apollo 11.

Goddard voice, Houston COMM TECH. Goss conference.

You're loud and clear. How me?

Roger. Read you the same.

Madrid, Houston COMM TECH. Net 1, voice check.

Houston COMM TECH, Madrid. I read you loud and clear.

Roger. Read you loud and clear also.

Hello, Houston. Apollo 11.

Apollo 11, Houston. Good morning.

Good morning. Are you planning a midcourse correction 4 this morning?

That's negative. Midcourse number 4 is not required. We were going to let you sleep in until about 71 hours if you'd like to turn over.

Okay. That'll be fine.

Say again, Buzz. You were cut off there.

Okay. I'll see you at 71 hours.

Roger.

Apollo 11, Apollo 11, this is Houston. Over.

Good morning again, Houston. Apollo 11.

Roger 11. Good morning. When you —

Would you like the O₂ purge this morning?
