Spacelog Apollo 8

Roger. You might be interested to know the center window is pretty well fogged up, but the other four seem to be in pretty good shape.

Glad to hear you've got four out of five, and your big dump will be coming up in 2 minutes or so.

Roger. We're standing by.

The S-IVB has started dump.

Houston, Apollo 8.

Go ahead, Apollo 8.

Roger. Mike, did you say star 14 was good till about 05:30 or something?

Yes. Stand by while I give you that time again. Star number 14 should be good for about another 8 minutes, Jim—7 minutes.

Okay. Now be advised, the optics calibration is very difficult to do because of all the other little stars floating here. I'm going to …, bypass it and do it at the end of this.

Roger, Apollo 8. Understand.

You should have the LOX dump now, Apollo 8.

Houston, this is 8. I'm looking through the scanning telescope and that LOX dump and just blanked out completely the entire scanning telescope.

Understand.

It's a fantastic sight, Bill. Looks like the S-IVB, a small attitude excursion while it's dumping.

Apollo 8, Houston.

Go ahead, Houston. Apollo 8.

Roger. I've got a flight plan update for Bill if he's ready to copy.

Stand by.

Stand by.

Ready to copy.

Okay. We are about 05:10 GET where we will record the BLOCK data TLI plus four and TLI plus 11. The TLI plus four PAD that we gave you before is perfectly all right. We will not require that one, and we will have the TLI plus 11 hour PAD for you shortly, then at 05:45 or 6 hours on that high-gain antenna checkout. Roger. Standing by.

We are on OMNI D, and we heard—we lost you after—TM plus four was okay.

Okay. The TLI plus 4 hour PAD is okay. We will have the TLI plus 11 hour PAD for you shortly, and at 05:50, for your high-gain antenna checkout, we would like you to leave that switch in WIDE BEAM with reference to our conversation the other day; leave it in WIDE.

Roger. Don't want to zap your receivers.

No, it has to do with some loss of tracking data, so it is better to leave it WIDE.

Houston, Apollo 8. Are you recording what we are getting out of 23?

Stand by one, Jim; I'll check.

That is affirmative, Jim; we are copying your P23.

Pretty big numbers there.

Well, we think that is because you bypassed the trunnion check.

Houston, we are getting some really big numbers in DELTA-R and DELTA-V.

Roger. Understand, Jim.

Apollo 8, say again.

Do you want us to accept these, or should we leave them alone?

Stand by.

Apollo 8, Houston.

Go ahead, Houston.

Roger. We do not wish you to accept those marks. This is due to the fact that in bypassing the trunnion bias check, you still have big numbers left in those registers, so you go ahead when—after you do the trunnion bias check. Those numbers will become small later, but do not accept them right now.

Understand, Houston.

We have a TLI plus 11 hour update for you when you are ready to copy.

Stand by.

Roger. Ready to copy TLI plus 11.

Roger, Bill. TLI plus 11, and this assumes no midcourse correction number 1: it's an SPS/G&N; 63330 minus 163 plus 129. Are you with me so far?

Roger.

Okay. 013:56:47.59 minus 00489 plus 00000 plus 47250 177 144 000, not applicable, plus 00197 47253 554 47050 12 1278 256 023, up 265, left 18. Are you with me so far?

Roger.
