Spacelog Apollo 8

Alright. And I'm gonna—you bug me when you get over 50 degrees of yaw, so I'll probably be watching that number pretty closely. We'd like to have the BIOMED switched to the right position. Okay. And for your own information: the fuel we show in the different quads I have here if you would like to copy it.

Stand by.

Okay. Ready to copy.

Okay. I'll give you the percentage on Alfa 60, Bravo 57, Charlie …

Wait a minute. It asks for present time, and I can't plot that fast, Ken.

Okay. I'm sorry. Alfa is 60.

For what time?

91:36.

Okay. Stand by.

Okay. What's Bravo?

Okay. That's 57.

Okay.

Charlie 62.

Okay.

And Delta 57.33842.

That's a coincidence. That's just what I worked out on Lovell's slide rule.

How are we doing on the cryos?

Oh, you've got some pretty good numbers on that that I sent up yesterday, and you had about 160 hours. Well, I'll check that out, but you were fat on cryo. I've got some SPS DELTA-V. You've got 33:20. You fly the service module RCS through the DAP. You have 142; and through SCS, it's 121.

Roger.

Apollo 8, Houston. We can't monitor on low bit rate whether you started your fuel cell purge. If you haven't, we can still go ahead and start now; and if you can, keep us posted as you go through it.

Roger. You want an O₂ and an H₂ purge, Ken?

That's affirmative.

You shall have it.

Apollo 8, Houston —

Go ahead.

It looks like you may be in OMNI Alfa. Can you confirm that we're set up to switch between Bravo and Delta?

You are now.

Okay. Thank you very much. And you are in the fuel cell purge?

It's complete.

Okay. Understand the purge is complete. Thank you. And in reference to your cryo, it looks like we'll have 180 pounds in each oxygen tank at SEP and 11 pounds in each hydrogen tank. And you're well above the single tank capability.

Apollo 8, Houston in the blind. Your yaw is 42 degrees. Recommend you set pitch and yaw to ATTITUDE HOLD for PTC. Over.

Apollo 8, Houston. Over.

Apollo 8, Houston. Over.

Apollo 8, Houston. Over.

Apollo 8, Houston. Over.

Apollo 8, Apollo 8, this is Houston, Houston. Over.

Apollo 8, Apollo 8, this is Houston, Houston. Over.

Apollo 8, Apollo 8, Houston, Houston. Over.

Apollo 8, Houston. Over.

Apollo 8, Apollo 8, this is Houston, Houston. Over.

Apollo 8, Apollo 8, this is Houston, Houston. Over.

Apollo 8, Apollo 8, this is Houston, Houston. Over.

Houston, Apollo 8.

Apollo 8, this is Houston. How do you read?

I read you loud and clear; my COMM here must have come unconnected.

Roger, Bill. We lost data on you for 15 minutes and voice COMM for about 45 and were beginning to get a little itchy. Is your PTC set up for rate command attitude hold?

Roger. Pitch and roll is in PTC.

Roger.

Apollo 8, Houston. Set up OMNI Charlie. Over.

Roger. OMNI Charlie.

Roger.

Apollo 8, Houston. We're showing yaw 54.5. Over.

Roger. It's been deadband right around there the whole time.

You can take command P00, also, if you want to. You might have to use it again.

Apollo 8, Houston. Say again.

Apollo 8, Apollo 8, Houston. Say again.

You can take over command P00; you might have to use it again.

Roger, Bill.

I'm trying to be quiet so the other guys can sleep, Jerry.

Apollo 8, Apollo 8, Houston. Over.

Roger.

Apollo 8, this is Houston.

Go ahead.

Switch to OMNI Bravo, and we'll try the Bravo-Delta switching again. Over.

You blew it.

We're on OMNI E now, Houston.

Roger, Bill.

Looks like B couldn't quite hack it; I'll put it back there in a minute.

Roger.

Houston, if your EECOM's need any more help, just tell them to give me a call.

We're going on OMNI Bravo now, Houston.

Apollo 8, Houston. Say again.

OMNI Bravo.

Roger. OMNI Bravo.

Apollo 8, Houston. Looks like we're getting pretty far off in both pitch and yaw. Showing about 50 degrees in pitch; and about 25 in yaw.

Apollo 8, this is Houston. All systems looking good. Over.

Apollo 8, Houston.

Apollo 8, Houston. Over.

Go ahead, Houston.

Apollo 8, this is Houston. Your systems are all looking good. Got a flight plan update for you: at time 96, you can delete P52. Your drift rates are real small.

Roger. And I'd like to do the chlorination at about 95:30 if I could.

Roger. Understand; chlorination: 95:30. Okay?

Houston, we're on OMNI C and going to Bravo now—correction, Dog.

Roger. Understand; going Delta.

We're on Charlie now.

Roger. Understand you're on Charlie. Break. Verify your UP TLM switch at COMMAND RESET is at NORMAL. Over.

Roger. It's in NORMAL. I've had the COMMAND RESET since we broke lock there, and I have to get back and control the OMNI's, so why don't you go command it over to Dog. Then give it back, and I'll set the other one on Bravo.

Roger.

Apollo 8, Houston. We have you on Delta; you can go to Bravo. Break. Give us a call when you've finished your chlorination. Over.

Okay. Everybody seems to be stirring around now, so we'll probably do it on time.

Houston, and the other two space aces are up now, and LMP's going to hit the pad and like to take a Seconal prior.

Apollo 8, Houston. Roger. Permission granted, Bill. Have a good sleep.

Thank you.

Apollo 8, Houston. Looks like you need about 3 more hours on that battery A charging. Over.

Okay. Well, my cohorts can handle it.

Roger.

Apollo 8, Houston. Can we get a crew status report on Bill before he goes to sleep?

He's feeling fine; a little sleepy.

Roger.
