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?

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.

Roger.
