Spacelog Apollo 8

Roger. Understand. Oh, I've got another score for you when you are ready to copy. Are you ready to copy?

Stand by. Go ahead.

Roger. Navy 14, Army 21. Would you like for me to repeat that? Over.

You are very garbled; Houston; I'm unable to read. Will call you back in another year.

Okay. We also notice the University of Houston lost their first home basketball game in 3-1/2 years last night. Illinois edged them out 97 to 84. And some really big news: the State Department announced only a few minutes ago that the Pueblo crew will be released at 9 p.m. tonight.

Sounds good. Outboard calculations indicate that Apollo 8 at 25 hours is 104 000 miles from home.

Yes. Our plot board shows a similar number.

Mighty nice view from here.

We're showing about 104 800 miles, and we're guessing another 8 to 10 hours on your battery charge.

Okay.

Frank, say again about the view. You were blocked, I think.

This is a mighty nice view we have down there today. A little bit more than a half earth. Looks like Africa and the Red Sea is visible; we're not quite sure as there is quite a bit of cloud cover; but even through the hazy windows, it's mighty nice.

How are your windows? Do you have a couple left that are real clear?

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.

Roger. Where are you taking it through, Houston?

It comes through Madrid and then Ascension, Bill.

Apollo 8, Houston.

Apollo 8, Houston. Over.

Apollo 8, Houston. Over.

Apollo 8, Houston. Over.

Apollo 8, this is Houston. Over.

Apollo 8, this is Houston. Over.

Houston, Apollo 8. How do you read?

Roger, Bill. We are reading you loud and clear now. We had an antenna problem down here. We had an unexpected switch of antenna, which probably caused your high gain to quit.

Roger.

Apollo 8, Houston. Over.

Go ahead,Houston. Apollo 8.

Roger, Jim. When we lost our antenna down here, we interrupted your tape dump, so we are in the process of doing some rewinding and continuing the dump, in case Bill is wondering what is going on with the tape recorder.

Apollo 8, Houston. Over.

Go ahead, Houston.

Roger. At 26 hours GET, we'll be switching our antennas back again at Madrid, and you can expect a glitch on your COMM system.

Roger.

Houston, Apollo 8.

Go ahead, Jim.

I noticed that you skipped the IMU alignment for about 26 hours because we were still asleep. Do you want to include that again, or do you think it is required?

Roger, Jim. We think it is going to be required prior to the next set of P23 sightings, and we're suggesting that it be put in at 27:45. We'll have a flight plan—a more complete flight plan update in here shortly.

Okay. Fine. We're in the process of having breakfast.

Apollo 8, Houston.

Go ahead, Houston.

The tape dumps are complete; it's rewound. You can go ahead and record in low bit rate if you …

Apollo 8, Houston.

Go ahead, Houston. Apollo 8 here.

Disregard. We were going to talk about the high gain, but you beat us to it.

Okay.

Apollo 8, Houston.

Go ahead, Houston.

Roger, Jim. We would like to take control of the tape for a few minutes to make sure that we got all that last dump. Over.

Okay. Stand by one.

Roger.

You've got it.

Thank you, sir.

Houston, Apollo 8.

Apollo 8, Houston. Go ahead.

Roger. I just noticed that I can hear those RTC's coming through on normal voice.

What does it sound like, Bill?

A little squeak.

Apollo 8, Houston. Over.

Go ahead.

Roger. I have a flight plan update for you sometime at your convenience.

Alright.
