Spacelog Apollo 8

Roger. Minus MA procedure okay for abort when GERU less than 07990.

Roger. I'll read back the entire remarks now just to make sure we got it straight. Use P37 NC-4, steps 1 through 11; then proceed to longitude control for no COMM procedure on page NC-7; average Victor 400K for corridor control chart is 36253; Minus MA procedure is okay after abort when GERU is less than 07990.

Apollo 8, Houston.

Go ahead.

Bill, you can turn on the H₂ purge line heater now.

Apollo 8, Houston.

Go ahead, Houston.

Jim, when you get a chance, either you or Bill, would you give us a crew status report on you and Bill?

Roger. We're going to finish up this one set of stars for you, then we'll do that.

Okay.

Have you been getting this data down there in Houston?

That's affirmative, Apollo 8.

Jim, so far we've only missed one point; we'll ask you to read it back a little bit later.

Which one do you need?

Apollo 8, Houston. You can reestablish PTC same attitude, 224 and 20.

Roger, Houston. I'm heading that way now.

Apollo 8, Houston.

Go ahead, Houston.

We'd like to have you start your waste water dump as soon as you can; dump to 20 percent. We're doing this in order to get 71 percent at LOI. Over.

Understand; 20 percent.

Apollo 8, Houston.

Go ahead, Houston.

Roger. We see waste water coming down now. While it's on its way down, how about a cryo fan cycle?

Okay. Cryo fan cycle; I'll cycle H₂ and O₂ fans, one at a time, 2 minutes each.

Apollo 8, Houston. We're showing you at 20.0 percent now.

Roger. We're showing about 25. We'll shut it off now.

Roger. Next on deck is the fuel cell H₂, O₂ purge.

Okay. Houston, we're ready to start the purge.

Roger, Bill. While you're purging, can you give us a crew status report?

That's going to be O₂ and H₂. Is that correct?

Roger.

You know, it's really too bad the side windows are fogged up because we never see any sun in the rendezvous windows, and we can't get very good pictures through these foggy ones.

Roger.

Start number 3. H₂.

Okay. Start number 3, O₂.

Roger, Apollo 8. Apollo 8, this is Houston. Would you set for ACCEPT for a P27 update, state vector to your LM side, and we'd like you to -

Say again.

Roger, Bill. Would you set up to ACCEPT a state vector update? We'll be putting it in the LM slot, and do not unzap. Over.

Roger. NORMAL ACCEPT.

We're going to put the word “zap” back in the dictionary.

Roger, Batman.

Houston, Apollo 8.

Apollo 8, Houston. Go.

It might be interesting to note that after NAV sightings, we ran out P21, and we get a pericynthian now of 66.8 miles.

Roger, 8. We copy.

I knew if he did it long enough, he'd finally get one that was close.

Okay. Start fuel cell 2.

Roger.

Apollo 8, Houston. Your state vector update is complete and verified. You can have the computer back in BLOCK. Over.

Roger.

Okay. Going to number 1, O₂.

Roger, Bill.

Old Helmut Kuehnel's kitchen timer is pretty nice.

Roger, Bill. You can turn off your H₂ heaters now.

Wilco.

Bill, we show you 168 000 out, and we're getting—still getting pretty good high bit rate off the 30-foot dishes.

Okay. I'm in NARROW BEAM high gain now. Were you getting good high bit rate on the OMNI?

That's affirmative. We're back on high gain now.

Okay. Number 1 O₂ is off, and will you clarify your previous statement. Were you getting good high bit rate while we were on the OMNI's about 10 minutes ago? Over.

Apollo 8, Houston. That's affirmative. We were getting fairly good high bit rate with a little bit of noise.

Okay. Thank you.

Roger. We only got two things left to do now. We need your crew status report and a redundant component check.

Jim will give you the latter—former, and I'll give you the latter.

Okay.

Bill, EECOM says thanks for the good job on keeping the OMNI's moving.

Roger. We'll make any sacrifice as long as they keep an eye on the systems.

Wilco.

Who's on the watch with you?

It's just me right now.

How about EECOM?

Well, we have Clint. The Black Watch is watching.

Okay. Stay alert.

Roger. The Black Watch is watching.

Roger. I'll stay alert.

Okay, Houston. Here comes the status report.

Roger. We're ready to copy.

Roger. For sleep, each of us has had two sleep periods; Frank's in his third one right now. Bill had 6 hours the last time; I had 4 hours the last time. Good to fair, both of us. Frank had 5 hours the last time, of fair. And Frank, of course, is sleeping now.

Roger, Jim. How are the three of you feeling?
