Spacelog Apollo 8

Apollo 8, Houston. Over.

Go ahead, Houston.

Roger, Apollo 8. Your Green Team will be signing off in a few minutes, and before we do, Charlesworth and the rest of us would like to say we have enjoyed it and look forward to seeing you back in Houston. Over.

We have sure enjoyed it, too, troops, and you guys have really done a good job. We really do appreciate it.

Well, nice words there. We will be seeing you, Bill.

Okay, Mike. We will see you, Buddy. Tell old Cliff adios for me, too.

Apollo 8, Houston.

Go ahead, Houston.

Apollo 8, we'd like to have you, before you get in a P52 going here, we'd like to have you rezero the optics and read us the mechanical CDU's. We're trying to collect a little data for troubleshooting.

Roger. Stand by.

Thank you.

What's the trouble you are trying to troubleshoot?

This goes back to some of the problems we had prior to LOI; trying to see if the software readouts we're getting down here compare with the mechanical readouts. It's not a current problem as far as we know.

Okay.

Apollo 8, Houston.

Go ahead, Houston.

Okay. Why don't you just read me the mechanical CDU's there now, and then it looks from the ground like you're clear to go ahead with the P52.

Okay. We'll get the navigator squared away here in just a minute.

Good morning, Captain.

Good morning, sir.

This will be a piece of stew out of a deep sleep. Okay, stand by one.

Trunnion mechanical CDU looks like it's reading about 1/100.

Roger.

And the shaft mechanical CDU looks like it is reading about 4/100 below zero, which would be about 364. Yes.

Understand, Jim. That is 4/100 below zero on that shaft; is that affirm?

Yes. Stand by one. About 35996 on the shaft.

Okay. Thank you. You can go ahead with P52 now.

I always said he did better in his sleep.

Apollo 8, Houston.

Go ahead, Houston.

Okay. It looks like we're getting down on the service module RCS to the place where we ought to go ahead and activate the secondary service module RCS propellant.

Okay. Stand by.

Apollo 8, Houston.

Go ahead.

Okay. We've got a new PTC attitude. For the pitch 180, and the yaw 315.

Roger. Yaw 315.

Roger. And pitch 180.

Okay.

Can't you pick one a little further away?

Not in our normal sphere.

Ken, this is Jim.

Go ahead.

Aren't we still a little high on the quantity side to activate the secondary?

Negative. We have quad Bravo and quad Delta which are getting right down, according to the calculated numbers, next to where we ought to be activating them. The numbers you are reading are going to be a little bit high, but the computer data on the ground shows that you have about 134 pounds in Bravo and Delta, and about 130 pounds is where you ought to be on the secondary.

Okay. Roger. We will activate the secondary and turn off the primary.

Okay. It's just to keep you from running one of them up.

Houston, Apollo 8.

Go ahead.

Ken, on this maneuver, MCC 7, are you going to—are we going to burn the PAD data that we got some time ago, or is there a new maneuver coming up, or what's going on in that regard?

Okay, Apollo 8. If required, we'll give you a new one. Right now, we are looking at not making a maneuver burn at all.

You say we may not even have another one now?

That's right.

Okay. You're the boss.

Apollo 8, Houston.

Apollo 8, Houston.

Apollo 8, Houston. Could you try another OMNI?

Apollo 8, Houston. Try another CMRI, please.

Apollo 8, Houston.

Apollo 8, Houston.

Go ahead, Houston. Apollo 8.

Okay. Read you loud and clear now. Just wanted to remind you that in the event of a loss of COMM, we don't want you to burn MCC 7. Your present entry PAD is good. We'll be updating your landing points at the same time that you would have gotten MCC 7, and I'd like to have a crew status report from you when it's convenient.

Okay, Ken. I understand. If we would lose COMM, you do not want us to burn MCC 7, just go ahead and use the entry PAD you've given us?

That's affirmative. You'll be within 0.06 degrees of your entry angle target line.

Alright. The crew status is everybody has gotten real good rest last night, and everybody is in good shape. Jim is just waking up, and Bill is starting the initial stowage, and we all feel very well.

Okay.

Houston, Apollo 8.

Go ahead, 8.

Apollo 8, Apollo 8, Houston. Go ahead.

Roger. Could you give us our range—correction, our velocity and range from the earth now?

Stand by.

Apollo 8, Apollo 8, Houston. At time 51, your velocity will be 9526, altitude 42946. Over.

Apollo 8, Houston. You call?

Apollo 8, Apollo 8. Did you call?

Negative, this is Apollo 8. We did not call you.

Okay. Thank you.
