Spacelog Apollo 8

Okay. Apollo 8, you can terminate the fans in the hydrogen, and we're ready to start on the oxygen tanks.

Apollo 8, we are through with the dump; you can have the tape recorder back.

Apollo 8, Houston. We are ready to go to the second O₂ tank.

Okay.

And for your information, it's Cleveland 24 to 10, and what we plan to do —

Say again.

That's Cleveland 24 to 10, not over yet.

Okay, Apollo 8. Looks like you can terminate your cryo fans now, and we're going to leave you alone for a while and let you get caught up. Things we have onboard, the high-gain antenna check, COMM mode check that you have listed at 7 hours, we'll put off and do whenever you are ready for it. So that's at your convenience. During the high-gain dump that we performed using a wide band, we were still getting real good data at 36K, which is a little bit further than circuit margins that were predicted for you. And we've got our SPS burn coming up somewhere around 11 hours, and we'll give you more information on that later.

Roger. We're doing the PROGRAM 21 now, determining ground track for LOI that we did not make at 5 hours.

Houston, Apollo 8.

Go ahead, Apollo 8.

Okay. We just broke lock on S-band high-gain. We're on OMNI B now.

Roger. OMNI B.

Apollo 8, Is that Bravo or Delta?

Dog, Delta.

Roger.

We can't get the PROGRAM 21 to integrate up to LOI; just stalled out around 69 hours and 2 minutes.

Roger. They are watching it.

Houston, Apollo 8.

Go ahead, Apollo 8.

Roger. Do you want us to stop the integration via VERB 96? Over.

That is affirmative; VERB 96.

Houston, this is Apollo 8.

Apollo 8, Houston.

Go ahead, Apollo 8.

Roger. Do you want us to hold off on this P52 realignment, also?

Yes, that is affirmative, CAP COM. We want to do that a couple of hours when it is related to the maneuver, midcourse.

That is affirmative, Apollo 8. Let's time the maneuver and we will hold off and do that all in normal premaneuver sequence. And—We have got a score here—in the fourth quarter, 31 to 13. And I've got some words on your P21 discrepancy any time you are interested. And I'd like to confirm —

Go ahead.

Okay. Before I get off on that one, I'd like to confirm that you used the VERB 37 procedure to go to P00.

Roger.

Okay. On P21, the thinking runs that you had a slight error in your state vector at the time you started, and when that was integrated out, it intercepted the lunar surface where it locked up and this is contained in a fairly recent program note.

Okay. Now, we've closed the—the waste vent, so we should see this O₂ come down now.

Okay. Understand you closed the waste vent, and how about the lithium change? Have you done that one?

Roger. That's done.

Okay. Thank you.

EECOM, FLIGHT. Did you copy that?

This conference communication is great. We won't have to have any debriefing.

(Laughter) That's pretty outstanding.

Right.

Houston, Apollo 8.
