Spacelog Apollo 8

We're all feeling pretty good now; no problems. We've all had about between 40 and 60 ounces of—or clicks of water so far today.

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.

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.
