Spacelog Apollo 8

Negative.

Houston, we haven't started 23 yet. Our CAL is zero.

Roger. Understand. Thank you.

We are in the process now to—to go to P23 attitude.

Apollo 8, Houston.

Go ahead, Houston. Apollo 8.

Roger. Downlink data shows that on star 33, Jim is using the lunar far horizon when he should be using the lunar near horizon. Over.

Okay. Thank you. 220?

Roger. 220.

Let us check it.

Roger.

You want the far horizon now, Houston?

Roger. Far horizon.

We have far horizon in now, Mike, on 220. I will check again, though.

Yes. That is right. We are requesting the lunar near horizon as per the flight plan, the lunar near horizon. We show that you are using the lunar far horizon.

Okay. Roger. I thought that you had copied up 220 to me. I will put it in the near horizon.

Mike, it's getting kind of damp—we're getting a playback, Mike. It is getting kind of damp in here. It might be a good idea to go back into AUTO on the temp in—the glycol temp in for awhile to try and get some of this moisture out of the cabin.

Roger. Stand by, Bill.

Roger.

Apollo 8, Houston.

Go ahead.

We concur. We would like you to go back to AUTO on the glycol temp inlet valve. Over.

Okay. When was our lowest radiator OUT TEMP during the last couple of hours while we have been in MANUAL?

I will get it for you.

And we are back in AUTO.

Roger. Back in AUTO, and 29 degrees is as low as we've seen.

Okay. We are showing a CABIN TEMP of about 76. It is very comfortable, but we are getting a lot of condensation on the walls now.

Houston, Apollo 8.

Apollo 8, this is Houston.

Roger, Mike. While we are waiting for the spacecraft to maneuver to the moon, I might note that as we get closer to the moon, the light from the sun comes right into the scanning telescope, and it is impossible to use. You have to rely on the sextant alone.

Roger, Jim. Understand that light from the sun is coming into the scanning telescope making it impossible to see, and you have to rely on the sextant alone. Can you attach any angle to that?

Well, Mike, I am right now at the substellar point of 33. I don't know where the sun is exactly from there, but that is about the angle. We're—the optics are pointed right at the moon now.

Apollo 8, Houston. We are going to be changing our antenna in a couple of minutes. You can expect a COMM switch-over.

Houston, Apollo 8. Over.

Apollo 8, Houston. Go.

Roger. The LMP is going to take a little snooze here for a while. I am wondering, can you give me a quick—your view of the system status here before I depart, and, also, give me an idea of when the next cryo stir is due?

Roger, Bill. Will do; stand by.

Apollo 8, Houston.

Go ahead.

Roger. Your systems remain unchanged. They are all looking good. You can go ahead and stir up the cryo starting right now.

Apollo 8, Houston.

Go ahead, Houston.
