Spacelog Apollo 8

Roger. Ready to copy.

Okay, Bill. This will be on page 2 dash 22 of your flight plan. For the command module pilot—I've already mentioned it to him—but at the top of the page, at about 27:45, actually, we would like him to do a P52, an IMU alignment, and then the P23 should be done as scheduled. Those four stars, Procyon, Regulus, Alphard, and Spica: we realize Alphard may not be too good a star, Regulus is about 3 degrees above the horizon, and Spica is at a 48-degree trunnion angle; so I guess what we are saying is if Jim has difficulty doing one set on each of those four stars, we suggest that he omit whichever one he is having difficulty with and pick it up by doing two sets on some other star that he likes. Over.

Roger. Understand.

All right. In the lower right hand corner of page 2-22, the passive thermal control attitude should read “pitch 224 degrees, yaw 020.”

Roger. Copy.

And on the next page, at about 29 hours, you can resume the normal flight plan. We would like to make one addition; at 29:30, add a waste water dump. Even though one is not really required at that time, we would like to get the dump out of the way so we can track you uninterruptedly without any dumping, you know, as we are coming up on midcourse correction number 3. Over.

Roger.

That's about all, Bill. You got any questions on this?

No, it looks pretty good. We've been saving up some water of our own to dump here, so that will work out all right.

Very good. And don't ruin Jim's optics.

Right.

Apollo 8, Houston.

Go.

Apollo 8. Houston. Did you copy?

Roger. You got it.

Okay. We got it. We're sending you a LM state vector, and we would like you not to transfer that vector over to the CSM slot.

Roger.

Apollo 8, Houston.

Apollo 8. Roger. Are you still planning an MCC 2 at 28 hours? Over.

Stand by one, Bill. Bill, negative. Now that midcourse correction number 2 has been cancelled. Its magnitude was less than 1 foot per second, so we decided not to do it. Over.

Okay. Thank you.

And you've got the computer again, if you go to BLOCK.

Houston, Apollo 8.

Apollo 8, Houston. Go ahead.

Are you still computing the pericynthian time of 6910.

Stand by. We will get an update for you.

Okay.

Apollo 8, Houston.

Roger. This is Apollo 8.

Okay, Bill. We just got your readout on your voice tape, and we will be back with you on it shortly. Over.

Okay.

Houston, I'm going to be doing my alignment at this time. I'm in a good position for viewing the stars.

Apollo 8, this is Houston with voice check. Over.

Houston, Apollo 8. Read you loud and clear now. How us?

Oh, good. Reading you loud and clear. One, two, three, four, five, five, four, three, two, one. Am I cutting in and out still? Over.

Nope. All the numbers are coming up nicely.

Okay. Thank you, Jim.

Apollo 8, Houston. We are going to switch antennas at 28:20. Stand by for our blitz.

Roger, Houston. And we will start passing thermal control, and we are maneuvering to P23.

Houston. Apollo 8.

Apollo 8, Houston. Go.

Roger. You copy high bit rate now for this P23?

Negative, Bill. We are getting low bit rate now.
