Spacelog Apollo 8

Go ahead, Houston. Apollo 8.

Okay. We've got a telescope alignment if you'd like to give it a try. Your sextant star is still good, but if you had problems with that, folks have worked out that if you look through the telescope at 10:35, we have a shaft and trunnion that should point you at the center of the earth, if you would like to give that one a try.

Okay.

Okay. At 10:35, the shaft angle 006.2, trunnion 18.9. Over.

Roger. 10:35: shaft 006.2, trunnion 18.9.

Apollo 8, Houston.

Go ahead.

Okay. We'd like to get a fan—a cryo fan cycle in here before the burn. About 1 minute on each should be fine.

Roger. I've already given 2 minutes on H₂ 1 and 2 and O₂ 1, and I've just started O₂ 2.

Roger. Thank you.

Apollo 8, Houston. We'd like to dump your tape prior to the burn.

Roger. It's only been running here about 15 minutes.

Okay, Apollo 8. That's—that's correct. You're on high bit rate, and we're afraid you may run out before the burn, so we'd like to dump it, and give it back to you with a full load before the burn.

Roger. And give us a comment on the voice quality.

Wilco.

Houston, Apollo 8.

Go ahead.

Roger. We plan to stop charging battery B about another 5 minutes. You concur?

That's affirmative.

Okay. You might just remind us.

Apollo 8.

This is 8. Go ahead.

Apollo 8, Houston. If you'll go high bit rate, we'll give you a tape recorder back to your command.

Apollo 8, Houston. If you'll put your high bit rate on, we'll give you a tape recorder back.

Houston, did you give us a tape back? Over.

Affirmative, Apollo 8.

Apollo 8's COMMAND RESET to get tape motion, we're now in NORMAL.

Roger.

Apollo 8, stand by for a mark at 1 minute.

Roger. Apollo 8 standing by.

Ten seconds.

Five seconds.

2, 1 -

MARK.

One minute.

Houston, Apollo 8.

Go ahead.

Roger. The burn time was on time—about 2 seconds; we have residual 4.4 X. We burned it out to 0.2. Attitudes are nominal. The DELTA-V_C before the residuals were taken out was a minus 2.4. I have transferred the state vector to the LM's slot in VERB 66.

Roger. Copy 4.4 for X and 2.4 on Z. And negative residual on Y prior to the trim. Is that affirm?

That's affirmative, and we took out the 4.4 residual down to 0.2.

Roger.

Houston, Apollo 8. Do you want us to start charging battery A, now?
