Spacelog Apollo 8

Roger. It depends on which way your nose is pointing.

Touché.

You might note for the people at MIT that the next series of stars will be shot by the master navigator with a space helmet on and long eye relief eyepieces.

Roger. That ought to cut his speed down a little bit.

Right.

Frank, while you are talking about the entry checklist, this cold soak—have you decided exactly where you want to do it there prior to entry

Well, I understood that EECOM talked that over with Bill, and we do it 1 hour prior to entry. We'll do it wherever you say is the best.

Okay. One hour is fine. It's just a matter of finding time in the time line to do it.

I think we can initiate it 1 hour before SEP.

Okay. Fine. Sounds like a winner.

Really got all zeroes with that helmet on.

Roger. We just noticed that.

Jim's going to leave the helmet off now for the rest of them, I think; it gets a little anoxic in there. These helmets don't have face plates, and we have a difficult time breathing with that on.

Okay. Jerry, that completes the P23. Did you have something else you want us to do now? You wanted to check on something from the last set.

Roger, Frank. We need to get some numbers that we weren't able to copy down here. Stand by just one. Frank, on your first P23, we missed three marks on star number 2. We missed mark number 3 trunnion.

Okay. Three trunnion is 05650.

Okay, 05650. Then star number 1, mark 2. We need the trunnion on that one, too.

04216.

And on star number 1, mark 3, the DELTA-R and DELTA-V.

DELTA-R is 00006, DELTA-V 00001.

Roger. Four balls 6 and four balls 1. Okay. Frank, your PTC attitude is pitch 180, yaw 315, and roll rate 0.3 degrees per second. The reason for wanting to point it north is not because we are concerned at all about any changes due to venting, there's been, as we can tell, no effects on your trajectory by venting. We just want to try out that direction on it.

That's fine. We are going to stay in for about two more seconds while Jim takes the pictures through the sextant for the optics people.

Okay, Frank. And then, also, we are looking for a fuel cell O₂ purge when you get a chance.

That's right. At—I got the word now; it's supposed to be at 124:30.

Right.

Apollo 8, Houston.

Go ahead.

Roger. For your P37 that's coming up that you are going to run, use a midcourse 7 time of 144:46. Also just a little note here, the trajectory is looking so good, it looks like you can make the corridor without even making a midcourse 7.

Roger. 144:46 for the P37.

Affirmative.

Thank you.

Jerry, this is Jim.

Go ahead, Jim.

Okay. No, they say hold it up for a little while.

… so you can see, the same data that Dr. Berry got on me in Gemini VII is also good for Frank on Apollo 8.

Houston, Apollo 8. —

Apollo 8, Houston.

Do you see that PROGRAM ALARM we got when we went through P37, 1302?

Affirmative.

I'll run through it again and see what happens here.

Roger. We're monitoring.

Apollo 8, Houston.

Go ahead.

Looks like you loaded the wrong time in P37, You should load 144:46 for your midcourse time; looks like you loaded 146:46.
