Spacelog Apollo 8

Okay. And in reference to the OMNI versus the high gain, it looks like we can live with the OMNI antennas here for several more hours, if you would like to delete the use of the high gain.

Okay. Goodnight, Houston.

Okay. Before you pitch your eyeballs there, we'd like to terminate the battery charge.

I knew you guys would get me.

Got you.

Okay. The battery A charge is terminated at 37.3 volts.

Okay. Thank you.

Standing by for your systems status.

Okay. We're pulling that together now.

How are the PU valve and SPS line temps looking?

Okay, I'll test that.

Systems look okay to you Houston?

Okay, Apollo 8. All the systems—giving a quick look around the room—look real fine. You've got an RCS quad update on the quantity, so you have that information. The SPS oxidizer feed-line temperature and the fuel temperature are both at 73 degrees. The cryo profile is running right on the line: Battery A—our calculations have 39.63 amp hours. Battery B, 37.94, and battery Charlie, 38.46. The COMM continues to be running ahead of predictions in quality and circuit margins. Everything else looks like it's real fine.

Roger. Do you expect to have a low bit rate voice on the DSE off the OMNI's at lunar distances?

That's negative on DSE off the OMNI's. Not looking forward to that much improvement.

Roger. We need about a 30-foot dish, I figure, for that on the spacecraft.

Roger. It runs up the fuel required for PTC, though, Bill.

Apollo 8, Houston.

Go ahead, Houston, Apollo 8.

Okay. I know you're trying to be quiet, so I'll just read up some information to you. One of the things that we just turned up that might give you some confidence, if you lose oxygen cryo tank now: you have 80 pounds remaining now at CM/SM SEP. The limiting factor on single tank operation right now is the hydrogen tank which has a positive margin at CM/SM SEP, assuming our standard profile gives you about 143 hours. So it looks like you are over the hill on those. Notice that you're flying in the rate 2 position for you BMAGS which is fine. Only make sure that you still were maintaining a PTC attitude. Looks like you're pretty close to it.

Roger. We are flying PTC, and I was wondering why it was going out of the deadband; now I know. Thank you.

Okay. Thank you.

That's what happens when you let Anders fly. He's asleep so he can't defend himself.

Roger. But we've got it on tape though.

Good. They're both conked out; how about just filling me in on some news, and I'll keep quiet just to give me some words on what's going on in the world.

Houston, Apollo 8. How do you read?

Loud and clear, Apollo 8.

I'm going to have a maneuver PAD and —

Houston, Apollo 8. How do you read?

I read you loud and clear, Apollo. 8. How me?

Apollo 8. Houston.

Hello, Houston. Apollo 8. Houston, Apollo 8. How do you read?

Hello, Houston. Apollo 8. Go ahead.

Apollo 8, Houston.

Apollo 8, Houston.

Apollo 8, Houston.

Hawaii Network GOSS Conference. How do you read?

Houston, how do you read? Apollo 8.

Apollo 8, I read you loud and clear. How me?

Houston, Apollo 8. How do you read?

Apollo 8, Houston. Over.

Go ahead, Hawaii M&O. This is Apollo 8. How do you read?

Apollo 8, Houston. Read you loud and clear.
