Spacelog Apollo 8

Okay, Apollo 8. I'd like to run one more null bias and looks like we will have exercised everything we can get to.

Okay. DELTA-V AUTO, all zeros.

Minus 2.

Roger. Understand minus 2. Alright. Is that minus 2 or minus two-tenths?

Two-tenths, three-tenths now.

Okay. Real good. That looks like we —

It looks like we had a lot of noise on the circuit for a while there, Ken.

Yes, we did, too; all those electronic glitches I guess.

Okay. One hundred seconds, it's plus—minus four-tenths.

Okay. Real fine. That looks like that's about all of the functions that we can check, and looks like everything is just down the line.

Roger.

Okay. We still owe you confirmation that you can expect your high speed scroll to be the first pattern you come to, and I'll let you know as soon as they come in with an answer on it.

Okay.

I'd like to go ahead and finish going through the entry book if you're ready.

Roger.

Okay. We've reviewed most of the book up here, and we will have to come back and suggest a way that we can check out the water boiler prior to getting reentry area. We've reviewed all of the last minutes changes that were put in—pen and ink type things—and they're all looking good. On page E-7, like to add a couple of items.

What's that?

Okay. On step 34 under final stowage, which is a sort of catch-all area, there's a step that says secondary glycol to radiator, and it says bypass, verify. While we are down in this area, we would like to go to panel 382, the water control panel, and set up the evaporator water control valve both primary and secondary to AUTO. Now this is something we would have done had we done the cold soak at minus 12 hours, but since we weren't doing it there, we would like to go ahead and make sure we have these in AUTO, and this will enable automatic controls from the panel.

Can we just make this part of the procedure when we test out the water boilers beforehand?

Yes, sir. If we get that checked out earlier, we can just leave them in AUTO.

I'd rather do that.

Okay. I'm just going to make a note here, and we can do it the other way, too. The other item that was pen-and-inked in —

…

You may already have this down as step 35. It says UP TELEMETRY to BLOCK, VERIFY, and there's a step right after that that says RCS command module heaters to circuit breakers CLOSED.

Roger.

Okay.

I have that.

Okay. I guess that one was sent up to you this afternoon. And when you turn the page over to E-8, it shows the EMS entry check being run at minus an hour, and you know that it's a short test. There is really no reason to wait for an hour; we might as well go ahead and do that as soon as you get through with step 35 on page E-7 because we're coming up on a pretty busy period.

I say that's fine; we'll do that.

Houston, are you still there?

Roger. We got a discussion going; be right back.

Okay, Apollo 8. On page E-9 —

Okay.

Okay. Tell me what to write in, Ken.

Okay. It's glycol evaporator water to AUTO.

Apollo 8, Houston. Are you there?

Glycol evaporator water switch to AUTO.

Okay. And the second switch is the glycol evaporator steam pressure to AUTO.

Okay.

Okay. That takes care of getting the primary water boiler enabled, and it's my understanding that we were going to make the actual entry with both the primary and the secondary water boilers on the line.

I'm not reading you now, Houston.

Roger. How now?

Loud and clear.

Okay. There's some question from reading the checklist. It is my understanding that both the primary and the secondary water boilers will be ON for the actual entry, and don't find a place in the checklist where it's actually turned on. So we'd like to get confirmation on that, and we'll make sure that we have all the proper switching to put in the checklist.

Okay.

Alright. Still on page E-9 and under step 39 at the bottom of the pyro circuit check, there's a step that says panel 8, all circuit breakers CLOSED except and then it lists five that are printed, one that was pen-and-inked before launch. It says EDS power circuit breakers 3 OPEN, and to be complete, we ought to add the RCS heater circuit breakers. There's two of those, and they should also be OPEN.

Okay.

Alright. The rest of these pages look good; I'm coming over through the graphs. And on page E-11 —

Roger. I'm with you.
