Spacelog Apollo 8

It's 5:18 17 16 15 14.

Thank you.

Houston, I will give you a mark in 4 minutes.

Alright. Thank you.

3, 2, 1 -

MARK.

Four minutes.

Apollo 8, Houston. How about switching the BIOMED switch over to the left.

Roger. 3, 2, 1 -

MARK.

Houston, Apollo 8.

Go ahead.

Roger. Burn on time, angles nominal, burn time about 12 seconds, 0.2 feet per second after the DELTA-V_C, 0 in VG_X. We have transferred the results of the burn over to the left slot VERB 66.

Roger. And got a couple of items that I would like to clean up. We will get you an RCS budget. We've got one redline now; we are trying to get some firmer numbers for you, and we will have those in a little bit. Right now your PTC usage is right on the flight plan line, so everything looks pretty good there. We want to get a crew status report from you. We would like to firm up the REV 2 flight plan idea; and sometime at your convenience, we would like to take a reading of the PRD for the commander and CMP and then have you swap them. We are trying to isolate the—what the possible reason is for the discrepancies or the disparity in the two readings.

Roger.

And we are maneuvering to the PTC attitude, Houston.

Apollo 8, Houston. Could you give us the sign of that Z residual?

Stand by, Houston. Alright, Houston. Looks like we didn't record just the Z. We recorded DELTA-V_C, which is minus 0.2.

Okay. Understand.

DELTA-V was 0.1, but we didn't get the sign.

Roger. Understand that was DELTA-V_C was minus 0.2. I copied DELTA-V_Z; ZULU is 0.2. Is that incorrect?

Roger. It was 0.1, but we didn't get the sign.

Okay. Thank you.

We can get it. We have it on the tape, Houston, whenever you want to dump it.

Roger. Thank you.

It'll be about the last 5 minutes worth.

Roger.

Okay, Houston, for the PRD's: CDR is 0.07, CMP is 0.64, LMP is 0.80. Note that the CMP's hasn't changed since we started and the commander's hasn't changed much. We have swapped PRD's; commander has LMP, CMP has commander's, and LMP has CMP's PRD. Over.

Okay. Thank you.

Houston, Apollo 8.

Go ahead.

Roger. Crew status report as follows: water, the commander has about 50 clicks so far today; CMP 43; and the LMP is 44. We've eaten two meals so far today. Day 3 meal A and B; consumed most of it except for the hard hard bite, which no one cares for. Pudding was outstanding. We're at a gain of pericynthian now of plus 63 miles. Commander and CMP have had a rest period just before the midcourse 4 of about 2 hours.

Houston, Apollo 8.

Go ahead.

Apollo 8, Houston. Looks like you're on the secondary loop. We would like to run that for about 5 minutes.

Roger. We're doing the ECS redundant component check.

Roger. We'll follow.

Getting any data now Houston? Guess you are. Okay. See you stopped my tape then. I've been running for about 3 extra minutes here to record the check.

Roger. We have data now. That was a temporary loss.

What's the matter? Was it chow time down there?

We just put compressor 2 on ac 2.

Houston, Apollo 8. Do you show battery B as voltage dropped some from the postcharge value? Over.
