Spacelog Apollo 8

If you can switch it down there without VERB 64, well, go ahead and do it.

We'll give it a whirl, Frank.

Okay.

… are all … of the earth.

Houston. … pitch and yaw of 10 and 45, aren't you?

Apollo 8, this is Houston with a battery status report.

Go ahead. We were just talking about the batteries.

Roger. At 96 hours EEP, battery A has 38.95 amp-hours; battery B has 36.35 amp-hours; battery C has 38.46 amp-hours. Your total, 113.76 amp-hours. At 97 plus 50, battery A will be fully charged and will have 40 amp-hours, and you can terminate charge at that time. Over.

At 97:50.

We'll give you back VERB 64, Houston..

Apollo 8, Houston. Say again.

We gave you back VERB 64. I wonder if you could have Guidance figure out a corridor correction at 114 hours for us with a minus 648 cabin.

Okay, Jim. We copy, and now we see we've got VERB 64 back. We'll be back with you in a minute.

Apollo 8, Houston. Over.

Go ahead, Houston.

Roger. We have a comparison now on your P37.

Roger.

Okay. Based on your vector, the CMC vector, the ground computes 15.3 feet per second on the midcourse, VEI of 36221, a gamma EI of minus 6.51 so it looks like your P37 program is pretty good. Applying your P37 solution to our MSFN vector, however, we get a gamma EI of minus 10.32. We expect these two solutions to converge with a little more tracking and after you get some earth horizon sightings. Over.

Roger. How valuable do you think that the lunar we did just after TPIR as compared to your MSFN tracking? Go ahead, Houston.

Apollo 8, Houston. Repeat your question, please.

Roger. I was getting curious of the value of onboard tracking in the P23 course close to the moon, in regards to the MSFN tracking that close to the moon. I think there might be a trail-off for onboard navigation, and I think it might be a little bit better than MSFN tracking.

Roger. Stand by.

Apollo 8, Houston.

Go ahead.

Roger. I guess the experts would say that the MSFN data was probably best based or the number of sightings that you have taken. However, that's going to be the subject of quite a bit of evaluation, I think, after the mission. Over.

…

Roger, Jim. Be advised that we are beginning to read you very weak, and with a rather loud background noise.

Understand. …

I'm reading—I'm reading you loud and clear.

Roger. Still reading you weak but clearer.

Apollo 8, Houston. You can turn off the battery charger. Over.

Hey, that sounds good, Jerry—good old roast beef and Yorkshire pudding.

Yeah, man. Is Frank listening?

Say hello to them for me, will you?

Sure will. Is Frank listening?

Frank's not on the line yet; he will be shortly.

Okay. How about Bill? Is he still asleep?

Bill is still asleep.

Okay. Have Frank give me a holler when he is ready. I've got a message for him, too.
