Frank Borman (CDR)

Houston, Apollo 8. How do you read?

Ken Mattingly (CAPCOM)

Loud and clear, Apollo 8.

Ken Mattingly (CAPCOM)

Roger. We had a momentary loss there.

Frank Borman (CDR)

How's the tracking data look, Ken?

Bill Anders (LMP)

Houston, Apollo 8 with a radio check.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Loud and clear.

Jerry Carr (CAPCOM)

Howdy. The Black Watch is watching.

Bill Anders (LMP)

How do you read on this—how do you read on this antenna?

Jerry Carr (CAPCOM)

Loud and clear on that one, Bill.

Frank Borman (CDR)

Houston, Apollo 8. Do you read on OMNI 3?

Jerry Carr (CAPCOM)

Apollo 8, Houston. Reading you loud with some background noise.

Frank Borman (CDR)

Roger. You are loud and clear.

Jerry Carr (CAPCOM)

Apollo 8, Houston. COMM check.

Jim Lovell (CMP)

Roger, Houston. This is Apollo 8. Loud and clear. How me?

Jerry Carr (CAPCOM)

Roger. Loud and clear, Jim.

Jerry Carr (CAPCOM)

Apollo 8, Houston with a preliminary LOI 1 PAD. Over.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Over.

Jim Lovell (CMP)

This is 8. Go ahead, Houston.

Jerry Carr (CAPCOM)

Apollo 8, Houston. This is a preliminary LOI 1 PAD. Over.

Jim Lovell (CMP)

Houston, Apollo 8. Ready to copy.

Jerry Carr (CAPCOM)

Apollo 8, this is Houston. Roger. LOI 1 SPS/G&N, 62844, minus 161, plus 129 069:08:18.41. Copy?

Jerry Carr (CAPCOM)

Roger, 8. Minus 29837, plus 02390, plus 00994 000 200 005 01693, plus 00600 29949 402 29782. Copy?

Jerry Carr (CAPCOM)

Roger, 8. 010 689 260 Persei Zeta, down 048, left 05. The remainder is not applicable. Sirius, Rigel, set of stars for GDC align, 129 155 010, negative ullage. We'll pass the horizon window data later. Over.

Jim Lovell (CMP)

Roger. Preliminary LOI 1 PAD as follows: SPS/G&N; 62844, minus 161, plus 129. Are you copying?

Jim Lovell (CMP)

069:08:18.41, minus 29837, plus 02390, plus 00994 000 200 005 01693, plus 00600 29949 402 29782 010 689 260, Persei Zeta, down 048, left 05. The remainder not applicable. Sirius, Rigel, 129 155 010. No ullage. We'll pass up the remainder up later.

Jerry Carr (CAPCOM)

Roger, Jim. One question—we talked about a P40 gimbal check. Would you like to do that during this maneuver to LOI 1 attitude, or would you rather hold that off until a little closer to LOI? Over.

Jim Lovell (CMP)

Let me check on that. Wait one, Houston.

Jim Lovell (CMP)

Roger. We could make this gimbal check as a maneuver to the LOI attitude.

Jim Lovell (CMP)

I understand that you'll load us up with the LOI 1 PAD and we'll run through P40 as far as the gimbal check.

Jerry Carr (CAPCOM)

Roger. That's what we heard you were going to do on it. Are you going to run both the manual gimbals as well as the automatic? Over.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Standing by to monitor P52. Over.

Frank Borman (CDR)

Roger. Houston, Apollo 8. P52 complete.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Roger. Copy.

Frank Borman (CDR)

Houston, how do you read? Apollo 8.

Jerry Carr (CAPCOM)

Apollo 8, this is Houston. Loud and clear.

Frank Borman (CDR)

Okay, Jerry. At 67, we are going over to the LOI 1 attitude, do a sextant star check, and then we will have to go back to PTC. I want to know if you want us to go back to the same attitudes we are at now?

Jerry Carr (CAPCOM)

Apollo 8, Houston. That is affirmative, Frank. We are getting ready to ask you to do an erasable dump, VERB 47. We are ginning up to get ready for it now, and we will call you as soon as we are ready to copy.

Frank Borman (CDR)

Understand. VERB 47 when you call.

Jerry Carr (CAPCOM)

Apollo 8, this is Houston. We are setting up for the dump now. It will take about 3 minutes and 20 seconds once we start the dump. Over.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Go.

Frank Borman (CDR)

Roger. Can you point out the position of this Zeta Persei to us a little better? We don't have it marked on our charts. We have got Mirfak, and we know Algol, but which one is Zeta Persei?

Jerry Carr (CAPCOM)

Roger, Frank. Persei Zeta is just about exactly between Aldebaran and Mirfak.

Jerry Carr (CAPCOM)

Apollo 8, this is Houston. We are ready for your CMC erasable dump. Key VERB 74 ENTER. Over.

Frank Borman (CDR)

Houston, Apollo 8. Are you getting the dump?

Jerry Carr (CAPCOM)

Apollo 8, this is Houston. Indications are that we are getting it; we are checking. You will have to leave the computer alone for 3 minutes and 20 seconds. Over.

Jerry Carr (CAPCOM)

Apollo 8, Houston. We are getting your dump low bit rate through Honeysuckle.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Persei Zeta is a third magnitude star same as Enif. Over.

Frank Borman (CDR)

Same magnitude as Enif.

Frank Borman (CDR)

Jerry, when are you going to send us the TEI 1 and the rest of that block data?

Jerry Carr (CAPCOM)

Apollo 8, Houston. PC plus 2 does not need an update. We'll have your TEI 1 and 2 in about 10 minutes. Over.

Frank Borman (CDR)

Go ahead, Houston. Apollo 8.

Jerry Carr (CAPCOM)

Apollo 8, Houston. The dump is complete; you can have your computer back. The reason for the dump was to investigate further the P52 anomaly you had about 4 hours ago. We will try to have some words for you in about 20 or 30 minutes. Over.

Frank Borman (CDR)

You mean when it wouldn't come up with the proper star?

Frank Borman (CDR)

We are going to go ahead and start our maneuver to LOI 1 attitude.

Jerry Carr (CAPCOM)

Roger. Standing by to monitor.

Jim Lovell (CMP)

During the flight, I noticed that the AUTO optics wouldn't drive to the star pick-a-pair selected. Example, it picked Alpheratz at one time, wouldn't drive there, drove to a spot that had no star; and I went back and reselected the program and came back, and it worked okay.

Jerry Carr (CAPCOM)

Jim, is this anomaly you are talking about—was that 4 hours ago when we did the REFSMMAT align?

Jim Lovell (CMP)

This happened, I think, yesterday. When we—we were doing a regular REFSMMAT alignment. Alpheratz was the first star selected, and it didn't drive to Alpheratz; and I ran and reselected the program again, and it worked okay.

Frank Borman (CDR)

Jerry, this is Apollo 8.

Frank Borman (CDR)

Our PAD here is—Roger. Our PAD here hasn't been correct. I understand the gimbal angles for LOI 1 are roll 0, pitch 200, and yaw 5. Is that correct?

Jerry Carr (CAPCOM)

Affirmative, Frank. That is correct.
