Spacelog Apollo 8

Hopefully, right after separation.

That sounds like a real good place. Okay. I'm sure we're going to discuss that one a little bit more, Bill. But right now those are the kind of things we're talking about doing. And on the high gain, there is still a lot of discussion about as to what—exactly what we saw and what it means. And I think it is a little too early to tell you anything about that one.

Roger. I think it's got X-ray eyes.

That's as good as some of the explanations.

Yes, I think that's what they hashed out on the ground, Ken.

Okay. I think we all agree that we don't want to try experimenting with it if we really don't know what it is we're looking at.

Roger. I've written down some numbers here that I hope will be helpful.

Okay. Fine.

And I'll give them to you in the debriefing.

Real fine.

I don't think it's any great big deal, because the antenna switching is not hard at all and the … is required to work; if it doesn't work as advertised, at least it works in a reasonable manner.

Ken, is it my imagination, or do you have the music running?

I'm sorry; say again.

Is it my imagination, or do you have the music running?

I think it's your imagination.

Uh-oh. Don't let the doctors hear that.

It's too late; he already heard you.

Apollo 8, Houston.

Go ahead, 8.

Roger. Just to make sure the urge to get red and blue filter shots of the moon haven't crept into this TV test. We have got red and blue filter shots of the moon, so you need not worry about that.

Okay. I don't think that would throw it away. I think we're trying to come up with something definitive so that postflight will have some real good data to compare with what we do on the ground for future work. I would like to have you go over and take a look at the battery Charlie, please.

I'm on my way.

Okay. Battery Charlie, that's about 36.8 volts.

Okay, 36.8. Thank you.

Roger.

Also with respect to the TV test, I would think that we could probably get a pretty good handle on the operation just by taking red and blue and polarizing shots of the earth independent of the TV, but within the same time frame or at about the same range we had the TV last time.

Okay. That's what—the second portion of this really is asking that we do this with the Hasselblad, and again we won't be using the red and blue filters so we have our baseline.

Taking a picture of the earth with the Hasselblad is no big deal because it does swing by the earth now and then. But trying to get the TV and the Hasselblad all pointed to the earth at the same time would really be tough.

Houston, Apollo 8.

Go ahead, 8.

Go ahead, 8.

We're going to hold up on the LiOH change for about a half an hour. The PCO₂ reading is low, and we don't want to wake up the CDR. It's right by his feet.

Apollo 8, Houston.

Go ahead, Houston.

Okay, Bill. We are coming up on the P52 and then the P23 sightings, and there is some concern that if we just go directly to P23 attitude that we are liable to overheat quad Charlie. So we would like to have you maneuver to place the minus X-axis towards the sun now. And I have some gimbal angles here for you. And if we take it over there and point the minus X at the sun between now and the time we have to start into the alignment, then the P23 business—we will tend to coldsoak Charlie, and then we will be able to go through the P23 operations without worrying about the temperatures.

Negative. That's quad Charlie.

Apollo 8, Houston.
