Spacelog Apollo 8

Just barely make out Clear Lake.

Your nozzle temperatures have dropped from about 94 to around 66.

Okay. I'm showing just a little bit above 50 percent here, and we'll keep on going, and if it looks too cold, give us a call.

Okay. We'll do that.

Houston, we had a momentary O₂ high flow, but we think it's due to all the purging of the water lines we're doing here in the cabin.

Apollo 8, Houston. We show you down to 25 percent of your waste water.

Okay. I'm just about 28, Houston. Stand by just a bit.

Okay. Waste dump stopped and then purge again.

Understand. Roger. Waste dump stopped.

Houston, we're on a high gain, and it might be a good time to try your COMM check.

Apollo 8, we're going to go ahead and crank up to a COMM test now, and we will be a little bit late on your update for 12 hours.

Okay.

Do you still want our—have us command as much as we can on the ground, or would you like to move the switches yourself?

Oh, you can have the fun of doing it.

Sounds like you're dragging there.

… you suggest a … We're using 1/250 on at f:11 on CEX and CMAX for earth shots. Do you verify? Over.

Okay. You got going before I got my pencil up. How about saying it again?

f:11 and 1/250 for CEX 16mm and C 70mm.

Okay. Thank you.

How about running in by the back room boys. My light meter doesn't seem to be helping out too much.

Okay.

Okay, Apollo 8. We're starting in—setting up for our first COMM test. This is going to be an uplink voice, ranging, and full downlink, which is not anything really different than what you have on board. I would like for you to verify that the S-band NORMAL MODE VOICE switch is in VOICE.

Roger. VOICE.

Okay. And the up-telemetry DATA to DATA.

Roger. DATA.

Up-telemetry COMMAND in NORMAL.

Roger. NORMAL.

High-gain antenna to AUTO TRACK.

Correction. That's -

AUTO.

We're in AUTO WIDE BEAM, and you can go ahead and dump the tape.

Okay. I'd like for you to go to NARROW BEAM.

Okay. Going to NARROW BEAM now.

Roger.

And I'll give you a call when we get ready to work on the tape.

Okay. We're still in PTC, so you're only going to have it for about 10 or 15 minutes.

Okay. We've had some problems with our displays, and I think they're straightened out now, but you may have to keep us advised if we run out of limits in case we display again.

Roger.

Say, while we're standing by here, Apollo 8, the service module quantities that we had listed—we're going to try to update them, if you want to call out your quantities. Have you checked them with your charts?

Negative. I haven't gotten around to that. Stand by.

Okay. There's no hurry on that. Just wondered if you had done it; we will check it against what we've got on our norma-gram.

I'm showing a SPS helium pressure, about 3570, indicated on board.

Roger.

And fuel LOX tank pressures are 177 and 176, respectively.

Okay.

N₂ A is 2400, B 2500.
