Spacelog Apollo 8

Go ahead. Say again.

Roger. Our first control point is very near the terminator, and as the optics were tracking it, I had occasion to watch the sun come up. And at about 2 minutes before sunrise, you get—the limb begins to brighten up into sort of a fine white haze, a fine glow completely over the space just behind the limb.

Roger. I understand. About 2 minutes before the sun comes up, you get a fine white haze radiating out from behind the limb. How far out does it extend?

It goes up quite a ways. It takes a fan shape, unlike the sunrise on earth where the atmosphere affects it. This just sort of is a complete haze all over the local area. It's concentrated at the exact spot where the sun comes up at ignition and then goes away from the sun spots. Very interesting.

Thank you, Jim. Thank you.

Apollo 8, Houston. We're standing by with your map and TEI 7 updates.

Stand by.

Apollo 8, Houston. You can go back to BLOCK with your computer.

Roger.

Okay, Mike. We're ready for the map update and then the TEI.

Okay. When you get your—before you get your map book out, the Houston COMM TECHS have got a little word for an old ex-CAP COMM. They say they consider you in NONREMOTE. Over.

Not permanently, I hope.

Okay. Your map update for REV 6/7: LOS 80:57:24, sunrise 81:06:57, prime meridian 81:13:02. Are you with me?

You cut out after the prime meridian. I got it, but not AOS.

AOS 81:43:05, sunset 82:13:54. Remarks: IP-1 TCA for B-1 82:07:39, and now I've got four more times for you which—acquisition times for when various things come over the horizon. Over.

Roger. Go ahead.

Okay. Control point 1, acquisition time 81:09:05; control point 2, acquisition time 81:21:48; control point 3, acquisition time 81:43:17. B-1 acquisition time 82:03:54. And I say again all those ACQ times are when they first come over the horizon. Over.

Roger. Copy, Houston. In about 2 seconds, I'll be ready for the TEI.

Alright.

I'm ready.

TEI 7, SPS/G&N—stand by one, Bill.

Just a matter of general interest, Houston: everybody is feeling good, and the CDR is taking a snooze.

Roger. Glad to hear it. We were just talking about a water dump down here. We've got one coming up, and it looks like on this REV prior to the time around LOS or just prior to LOS, would be a convenient time to do it. Do you concur?

Okay. We will. Down to 25 percent again?

That's affirmative, and we'd also be interested in any comments about what these various dumps have done to your optics, if anything, and how long the effects last after a dump.

Don't seem to have done anything to the optics, but they've definitely got in some of the windows. There are a few little chunks of ice on window number 1, which is nearest the vent, and also on window number 5 a little bit; windows 2 and 4 remain amazingly clear.

Roger. Thank you, Bill, and I'm ready to resume the PAD when you are.

Okay. Press on with the weight.

Alright. Weight 45701, minus 040, plus 157 083:18:20.80, plus 32346, minus 01168, plus 05730. Are you with me so far? Over.

Apollo 8, Houston. Over.

Go ahead, Mike.

Roger. I got down through DELTA-V, minus X, minus Y, and minus Z. Did you copy those? Over.

No, I didn't read a word. I'm still waiting for the weight.

Roger. Let's go back to the weight: 45701, minus 040, plus 157. Are you with me? Over.

Sounds good.

Okay. GETI 083:18:20.80, plus 32346, minus 01168, plus 4—correction, plus 05730. Are you with me? Over.

Roger.

Roger. TEI 7 SPS/G&N: 45701, minus 040, plus 157 083:18:20.80, plus 32346, minus 01168, plus 05730 179 9—correction, 009 001, NA. Are you with me?

Yes, I'm with you, Bill.

Plus 00187 32870 307 32676 32—correction, 420880 253033, down 121, left 27, plus 0790, minus 16500 12973 36238 146:44:14; same north set Sirius and Rigel, 129 155 010; four-jet, 15 seconds, 2 degrees, now horizon and peak.
