Spacelog Apollo 8

Okay. Thank you.

Apollo 8, Houston. If you'd go P00 and ACCEPT, we have our P27 ready. We'll send you up a REFSMMAT. Over.

Roger. P00 and ACCEPT.

Roger.

Apollo 8, Houston. Frank, we'd like to make sure you understand that when you do your P52, you want to select option 1, the preferred option, because those are the registers we're blinking now with this P27.

Roger. Option 1; thank you.

Apollo 8, Houston. We got a good load in; it's your computer. Go to BLOCK.

Okay.

Roger. Stand by.

And you can go ahead with your P52 at your convenience.

Apollo 8, Houston. Over.

Go ahead, Houston. Apollo 8.

Roger. When Jim gets to the end of P52, he's got a flashing VERB 37. We'd like him to not proceed, to hold at that point; we'd like to read some bits and pieces out of the computer at that time. Over.

Roger.

Apollo 8, if Anders has got time to give us a countdown, could we get the BIOMED switch from center to left?

Two, one -

MARK.

Did you take that 1.7-second time delay into account?

Sorry about that.

Okay. Houston, you have it.

Thank you, Jim. And I'll give you at estimate here on how long we want to hold at this point; it won't be too much longer.

Roger. It was my goof: I must have put in 3701 instead of 3723 and 501.

Roger.

Apollo 8, Houston. We have got a flight plan suggestion for you.

Go ahead.

Go ahead and delete the remainder of the P23's that you're working on now, go back to PTC attitude, and then pick up where it says 108 hours in the flight plan to pick up again there with your P23, or if you prefer to slip that time a couple of hours, if you want to get some rest in between.

I think that's a good idea; we'll do that.

Okay.

Mike, what does this do to our state vector?

Not a thing. We've looked at your state vector, and it's good.

So we didn't lose all the NAV we had just accomplished, right?

Stand by one on that, Jim. I don't know; I'm checking.

Apollo 8, Houston.

Go ahead.

Roger. I say again, your state vector is just fine; it's still ticky-poo, and the reason we're holding here is that we're checking to see if any P23 information was lost. That's reason one, and the second reason is that your W-matrix shares some computer memory cells with P01, and we are getting a clarification on the status of your W-matrix before we proceed. Over.

Apollo 8, Houston.

Roger, Frank. We're coming up on time for an oxygen purge on all three fuel cells. It might be a good time to do it while we are waiting here.

Fine.

Alright. Mike, we are going to purge the three fuel cells, oxygen only.

Apollo 8, Houston. That's enough on fuel cell number 1; if you'd start on two please.

Apollo 8, Houston. We're in low bit rate now. Last time we saw you, you were still purging. Over.

Roger. …
