Spacelog Apollo 8

Houston, Apollo 8. Are you ready to go—for us to go through with the P52 now?

That's negative, Apollo 8. We would like to update things first, and we're going to give you a LM state vector and then an external DELTA-V.

Roger.

And with P00 in ACCEPT while we'll go ahead and work on that.

Apollo 8, Houston.

Go ahead.

Okay. We've got your PAD's. We're ready to read up to you, And we're standing by to uplink your state vector and external DELTA-V whenever you're ready to give us ACCEPT.

Roger. Just stand by one, and we will get the PAD from you.

And we will put in—TM in ACCEPT now—at this time.

Roger.

We're ready to copy the PAD.

Okay, Apollo 8. I didn't copy that last one. We are sending you state vector up now.

Roger. We say we are ready to copy the PAD.

Houston, Apollo 8. MCC 1 maneuvers: SPS/G&N 63295 minus 163 plus 129 010:59:58.30 plus 00136 minus 00045 plus 00202 345 188 343 all 9's plus 01685 000248 002 00186 23 2013 164 012, up 27-6, left 04 November Alfa for the remainder. North set stars, roll 068, pitch 097, yaw 356, no ullage single bank—bank Alfa.

Roger, Apollo 8. That's correct. And I have a TLI plus—11 PAD for you.

Roger. Go ahead.

Houston, Apollo 8. Go ahead.

Roger, Apollo 8. Loud and clear now. Are you ready to copy?

Roger. Ready to copy.

Stand by.

Roger.

Houston, Apollo 8. To the readback. Are you ready?

Go ahead.

TLI plus 11 SPS/G&N 63140, minus 163, plus 129 13:56:48.97, minus 00599, plus 00000. And I believe it's plus 47016.

Affirmative.

177 143 000 NA, plus 00197, 47020 551 46818 12 128.3 257 023, up 263, left 17, plus 1195, minus 16500, plus 126 23 35608 050:47:05, the north set, roll 68, pitch 97, yaw 356, no ullage, P37 high speed, 7900 Indian Ocean, and high speed procedures for the MS are not required; assumed MCC 1.

Roger, Apollo 8. Two corrections on the GETI. The hour's 013. Range to go EMS.

013.

Roger. Copy that and the rings to go in the EMS 126 83. Over.

12683.

That's correct.

Houston, this is Apollo 8. Be advised that we doubted that it would be possible to use the stars to get our backup alignment. We haven't been able to see any stars through the scanning telescope yet.

Roger.

Okay. And another comment for you, Apollo 8; like for you to use VERB 37 to select P00 and then wait for your computer activity light to go off prior to unzap of the LM NAV to CSM SLA.

Roger. You ready for us to do that now?

That's affirm.

Houston, this is Apollo 8.

Go ahead.

Okay. Now we'll go ahead and start back towards the flight plan around 8 hours here of P52, right?

That's affirm.

Well, we—we have transferred—wait—we've transferred the state vector to the LM SLA already before we did a 52. So we're going to do the 52 now.

Apollo 8, Houston.

Go ahead, Houston.

Roger. Will you check your up-telemetry switch to BLOCK, please?

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.

Go ahead, Houston. You were cut out.

Okay, Apollo 8. All your systems are GO, and we were about to tell you you can go ahead and terminate the battery charge, and you beat us to the punch.

I read your mind, and it's showing 37 volts right now.

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?
