Spacelog Apollo 8

Roger. We confirm your flow and understand you're seeing particles now.

Not much, though. Okay. Now going to number 2.

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.

Okay.

The food: we're up to—we've eaten day 2, meal 2 so far. And both of us have eaten the rehydratables and the juices and about half of the solids.

Roger. Copy.

The cabin's running slightly cold. We do have one cabin fan ON, and we're in full heat, and it's running just slightly under 70. Might be a design note for future spacecraft.

Roger, Jim. That fan pretty noisy?

It's not as noisy as both fans when they're running; we cut it down to one fan.

Roger. We keep thinking we hear it when you're talking to us.

I wouldn't be a bit surprised.

Houston, we're showing a glycol EVAP OUT TEMP around 44, and a RAD OUT TEMP of about 28. I wonder if we might try some manual mixing here to raise the glycol EVAP TEMP OUT a little bit?

Okay. Houston, secondary loop is coming up.

Roger, Bill.

Okay. We're boiling the secondary EVAP, and the temperature's stabilized, and so we're gonna close up the EVAP pressure valve.

Roger. Copy.

Apollo 8, Houston.

Go ahead, Houston.

Roger, Bill. Before you try the manual mixing, we'd like you to give it a whirl at the manual and increase on the cabin TEMP. Over.

We've done that. We're in full HOT, and what is your—what's the lowest RAD OUT—individual RAD OUT TEMP you seen here during our PTC?

Roger. Stand by.

Apollo 8, this is Houston. We saw 26 one time.

Roger. Understand; plus 26.

Affirmative.

Apollo 8, Houston. Go ahead with your manual mixing. Suggest you set your EVAP OUT at about 55. Over.

Okay. We'll give that a try, and let us know if the RAD OUT TEMPs get too low.

Houston, Apollo 8.

Apollo 8, Houston. Go.

Roger. We have it stabilized about 53 degrees, and we will leave it there, but we will go back AUTO if you start having any concern about the radiators.

Roger, Bill. We are showing 51.4 here.

Apollo 8, this is Houston. We are going to have a command changeover to Honeysuckle in about 2 minutes. Over.

Roger, Houston. Standing by.

Apollo 8, Houston. That was Honeysuckle to Madrid.

Si, señor.

Goodbye, you chaps.

Houston, Apollo 8.

Apollo 8, Houston. Go.

Roger. Did you delete the cislunar NAV exercise at 47:15?

Houston, Apollo 8. How do you read?

Apollo 8, this is Houston. Buenas dias, muchachos.

Buenas dias. We're going to be answering your calls pretty quietly for a little while here to let the CDR get to sleep. If you can't hear us, why, just tell us so.

Houston, Apollo 8.

Apollo 8, Houston. Go.

Apollo 8, Houston. Go.

Roger. My two cohorts are going to try and get some sleep here, so y'all might keep a good eye on the systems. I'm going to move over to the other side.

Roger.

Apollo 8, Houston. We're getting low bit rate now. We could do better with a high-gain antenna before you move over to the other side. Over.
