Spacelog Apollo 8

Understand. And you are maneuvering to PTC. That's fine.

Well, I would prefer to do that, but we will —

Apollo 8, Houston.

Go ahead, Houston. Apollo 8.

Roger. We would like to hold off on the passive thermal control until 7 hours GET and, in the meantime, to get as many more P23 marks as we can, starting with the first star and doing two sets of three marks each, and then going to the second star we gave you. And concurrent with that, if possible, we would like Bill to run this high-gain antenna checkout if Lovell's attitude is compatible with that.

Okay. But they have not been to date. We are almost to the passive thermal control attitude now, and Jim is just halfway through taking his suit off.

Roger. Understand.

We'll have to hold off for a minute here.

Roger, Frank. And the reason for this is the horizon calibration requires a number of points to give you good data for the onboard NAV coming on.

Roger. We understand. We will be right back with you; just have to wait a minute here.

Roger. Thank you.

That failing to separate from the S-IVB kind of fouled us up a little.

Houston, Apollo 8. How do you read?

Apollo 8. Go ahead.

Roger. We are standing by. Are you about ready for the high-gain antenna trial?

Okay. Just a second; we will check on that. Then are you in a position where you can go back to the star sightings?

Well, we will be, but we can't until Jim gets ready.

Okay. We will stand, and you give us a mark on that. In just a second, I will check on the antenna. Okay. It looks like we are ready to go on the high-gain antenna check. And we can either go with commands called out from the ground, and you can monitor it, or you can be talked through it, whichever you prefer.

Well, stand by. I guess we are not quite in a proper attitude yet.

Roger.

Houston. Apollo 8.

Houston, Apollo 8.

Apollo 8, Houston. Did you call?

Roger. There is the high-gain antenna on wide auto.

Houston, Apollo 8.

Go ahead, Apollo 8.

Are you getting the results you want from our high-gain antenna?

Apollo 8, Houston. Affirmative. We are getting your data, and we may have a beam width change, but stand by on that.

Alright. We're standing by. Jim's about ready to go back to the P23.

Roger. We have a GO until 7 hours on the start of the PTC.

Roger. Seven.

Houston, Apollo 8.

Go ahead, Apollo 8.

We're on the PTC mode now waiting for Jim, and I noticed that out my window now I can see Orion very clearly, even though the sun is bright in the other window.

Roger.

It almost pained me to say that, but it's true.

Roger.

Speaking of the windows, the number 5 window is getting pretty well obscured and the number 3 window is unusable.

Houston, Apollo 8. We're maneuvering back now to do another P23.

Roger. Thank you.

Houston, this is Apollo 8. I'll do two more sets on 15, and then we'll do one set on 16.
