Spacelog Apollo 8

Stand by; guess we've got 85-foot site voice back now; the noise went away.

Apollo 8, Houston.

Go ahead, Houston.

Go ahead, Houston.

Okay, Apollo 8. That completes our COMM test. Thanks for your cooperation. And I've got a change here to NAV sightings that will come up at 32:20. And we want to change your star a little bit there. Are you ready to copy?

Ready to copy.

Okay.

Ready to copy.

Okay, Apollo 8. We would like to change the NAV sighting as follows: we would like to use star 26, that is, two-six; we would like to make it earth-near horizon for two sets, two sets. Then we would like to take star 16 earth-far horizon, one set. If star 26 earth-near horizon is not possible, star 16 earth-far horizon, one set, and star 22 earth-far horizon, one set. Over.

Roger, Houston. Be advised the CMP is asleep … putting those on for a while.

Okay. Stand by.

Apollo 8, okay; we can put this off. What we will probably need from you is some kind of an estimate of when you think somebody will be available to work on it, and we are working on how much lead time we need now.

Stand by …

Roger.

Houston, why don't you figure the CMP will sleep another couple of hours, then the LMP, and then the CDR up to about 43 hours equally. Over.

Okay.

Apollo 8, Houston.

Go ahead, Houston.

Okay. We can put off this NAV sighting. It was scheduled here at 34:20, and we can put it off, Judging from your comments about sleeping, we would like to get it as soon as we can, and right now, our plans are to slide it 2 hours. We will do the P52 by sliding it back to the same thing since it is associated with the P23. So If that's a convenient time for you, why we will plan on that.

We are doing the P52 now. Do you want us to continue?

Well, as far as we are concerned, that isn't going to help us any. We will have to do it over again anyhow.

Okay. And what time do you want to do it?

Well, if you think Jim's going to be up in a couple of hours, why that will slide us 2 hours to 36:20.

Okay. We will go ahead and make another one there and pick it up then if that's okay.

Okay. That will be real fine. Thank you.

What we are going to try to do is get back on the sleep cycle to those sleep periods just prior to LOI by taking shorter cycles for each man.

Houston, Apollo 8.

Apollo 8, go ahead.

How about giving us some REACQ angles, and we'll. stay in REACQ.

Say again, please.

Could you give us some REACQ angles?

Wilco.

Say again.

Apollo 8, this is Houston. I hadn't said anything at that time. We're digging some angles out for you now. In reference to your earlier question about the sleep cycle juggling and so forth: we agree with your comment. We would like to get back on the flight plan as far as the sleep cycles and so forth are concerned by the time we get into lunar orbit. So we'd like for you to use your own judgment about the most efficient way to accommodate the sleep cycles and proportion it up among yourselves. We would like to have you keep us informed of who's doing what and what your plans are. We have the one P23 that we had slipped 2 hours. We'd like to get the other one in. We can also adjust the time for the other P23, if it's going to conflict—I guess that's two more P23's. We can adjust the time for those if you'll let us know what your forecast is for when Jim will be available to take some sightings. So the big message is that we'd like to work around whatever your desires are. If you'll let us know, we'll pick some stars and some angles and have them ready for you.

Okay, Houston. The CMP will be up at 36 hours. The LMP is going to sleep now, and he'll sleep through until 40 and then I'll stagger that in and try to go to sleep around 30 to 37 so that by the time we get to day 3 we'll all be back on the same direct sleep cycle.

Okay, real fine. Thank you.

Hawaii LOS. Unable to find.

Apollo 8, Houston.

Apollo 8, Houston.

Hawaii, this is Houston CAP COM. Over.

Houston CAP COM, Hawaii.

Hawaii, Houston CAP COM. I would like to have a voice check.

Roger. I read you loud and clear.

Okay. I'm reading you loud and clear. I understand you have contact with the spacecraft. Is that affirm?

I have uplink voice to the spacecraft; the downlink is too low in the mud.

Okay. Understand that you have good uplink, but your downlink is in the mud. You don't have any way of copying it either, is that correct —

Houston, Apollo 8. … again. How do you read?

That is affirmative.

Okay, Hawaii, we can hear Apollo 8, calling down. Would you answer and tell them that we did copy that?

Roger.

Apollo 8, Hawaii M&O. Houston reports they copied your last.

Okay. Thank you.

Apollo 8, Houston. Over.

Hawaii, Houston Network, GOSS Conference.

Hawaii, Houston Network, GOSS Conference. Your NET 2.

Houston Network, Hawaii.

Roger. Did you copy the CAP COM?

Affirm. We copied the CAP COM.

Is he keying the transmitters out there?

He did key it one time, Network.

Okay. I'm going to ask him to call the spacecraft again, and I would like for you to give me a report if he does not key the transmitters.

Roger, Network. Is our NET 1 now conferenced up —

Your NET 2 is conferenced to our GOSS Conference here.

Roger. How about our GOSS Conference loop?

Your GOSS Conference loop is dead.

Roger. We are GO for command. We were unable to transmit before.

Understand.

We transmitted to the spacecraft as per CAP COM and they acknowledged our transmission.

Apollo 8. Houston.

Go ahead, Houston. Apollo 8.

Okay. We got back together again. You're loud and clear. We've been reading you. We have a problem down here on the ground getting our signal from MCC out to remote site.

Roger. Understand.

Apollo 8. Houston. I've got a ball score for you. It was Oakland 41, Kansas City 6 is the final score. That's 41 to 6, Oakland. We're trying to get some news releases over here for you. I suspect we're going to find that the staged TV show was probably the biggest news of the day.

I'm sorry that the TV lens broke down.

Well, we're working on that some more. I'm not sure that the whole thing is lost yet. It appears that our problem is one where the light intensity which is sensed by our light meter in there is picking up an average field which is much larger than the earth, and so it's sensing a great deal of deep space environment which is dark, and we're suspicious that this is probably opening up the lens aperture as wide as it will go, and then when you point the camera at the earth while the earth is only filling about 3 degrees of cone angle, whereas lens takes in 9. So it looks like you're probably just saturating the tube. Now we're playing around now with some —

We just lost you again, Houston.

Say again.

I just lost your last transmission; you were clipped.

0kay. Did you get any of my comments about the TV tube?

Roger. Got them.

Okay. What I—what we've got in mind here is that we are looking at some of the lenses you have on board for cameras, and we are going to see if one of them can possibly be used to attenuate some of this light so that you will be able to take one of these pictures, and we are running some tests now, and we'll let you know about those. I also have a maneuver PAD that I need to read up to you whenever it's convenient.

Let me get a pencil. Be fine right now.

Okay.
