Spacelog Apollo 8

The rendezvous windows are good. The others are all about the same as they were when we last reported. One and five have a slight haze and a little fog on the inside.

Apollo 8, Houston. Over.

…

Roger. Just as a matter of curiosity for Bill, we can say a few words about the heaters for the cryo tanks, and also for the fans. We've noticed that the heaters are doing their thing normally, cycling on and off; and as time goes by, this cycle rate increases, indicating a little bit of stratification in the tanks. And then when we've been turning the fans on every 4 hours for a couple of minutes, this stirs things up and the heaters then cycling on and off again more slowly for awhile, until again a little bit of stratification occurs, and the cycling becomes slightly more rapid. This is, of course, normal; we just point it out as a curiosity to you. Over.

Roger. I haven't really been following it that close. One thing I have noticed is when you turn the fans on you get a glitch in the quantity, which might correspond to a glitch in AC. Maybe the next time we'll look at the AC volts and see what happens.

Our experts say that's not the reason for the glitch. They say the stratification fakes out the capacitance sensor there for a second.

I knew they would have some big deal answer for me.

… got you today.

I'll buy that.

Roger.

Any other information you want us to send up to you?

No, we're going to zap you with the high gain here shortly.

Okay.

Houston, this is Apollo 8. How do you read on the high gain?

Reading you loud and clear, Bill. How me?

I'm reading you loud and clear. I'll go ahead and dump this. You might want to listen to it in real time to evaluate the voice.

Okay. We'll do that as soon as we can.

Give me a call when you are ready.

Do you want to dump it by your command, or would you like us to command the dump on it? Over.

Oh, you can go ahead and command whenever you are ready.

Okay. we are starting now; thank you.

I've already rewound.

Roger.

Roger. I've already rewound.

There is only about 5 minutes worth on the tape, Houston.

Roger. Understand, Bill. You promised me you would wait 3 days before you started doing this, Bill.

Apollo 8, Houston.

Go ahead, Houston.

Roger, Bill. We've got your dump, and the voice quality is very good. We we going to take about 20 minutes or so to get it back to Houston to play it.
