Spacelog Apollo 8

Go ahead, Houston.

Roger. We have a request that Jim space his marks, his five marks out a bit more slowly. If possible, we would like to get a couple of them past the zenith. We're getting five of them with rather rapid spacing, and from the geometry viewpoint, it would be better if you'd slow them down a little bit and lengthened them out so as to include a couple of them past the zenith. Over.

Roger. We understand.

Houston, Apollo 8. That last set of marks are invalid. Disregard what Jim drew the last time.

Roger. Understand the last set of marks are invalid. Over.

Roger. If you would correlate … the last set.

We have an awful lot of background noise, Jim. Could you say again, please?

Roger. I'm coming up on control point 3. I tried to stick another control point in between 2 and 3. It didn't do it, so I just took out our program, marked it down on the program.

Apollo 8, Houston.

Go ahead, Houston. Apollo 8.

Roger. On Jim's marks, we'd like to get spacing of approximately 30, 30 seconds between each mark. The last ones we are copying roughly 15 seconds between marks, and we would like to stretch it out even further if that is okay with you.

Houston, Apollo 8.

Apollo 8, Houston. Over.

Roger, Mike. I find that tracking is much easier using the sextant than the scanning telescope. You have finer control, and at these orbital speeds, resolved to medium seem to be the best combination.

Apollo 8, Houston. Over.

Roger. I'm not too sure what happened that time, Mike. I was marking on the landing sites, using the code, and I kept getting a large trunnion for AUTO OPTICS. And I could see the target, or landing site was coming up, so I just went manually and marked and got the—the latitude and longitude were quite different from the nominal.

Apollo 8, Houston.

Go ahead, Houston. Apollo 8.

Roger. We're checking into Jim's remarks on his P22; and in the meantime, I have your maneuver PAD's and map updates, at your convenience. Over.

Roger.

Go ahead with your data, Mike.

Okay. And before that, we'd like to take the DSE away from you, please, for a while.

All yours.

Thank you, and we'd like you to go to P00 and ACCEPT. We have a P27 state vector update for you.

There's P00, and I'm going to ACCEPT.

Thank you.

All yours.

Which would you like first, the map update or the TEI 8?

The map would be fine.

Okay. Map update: LOS 82:55:54, sunrise 83:05:49, prime meridian 83:11:38, AOS 83:41:43, sunset 84:18:45; remarks: control point 1 acquisition 83:07:39, control point 2 acquisition 83:20:21, control point 3 ACQ 83:41:51, B-1 acquisition 84:02:28. Over.

Roger. 82:55:54, 83:05:49, 83:11:38, 83:41:43, 84:18:45. CP-1 83:07:39, CP-2 83:20:21, CP-3 83:41:51, B-1 84:02:28.

That's affirmative.

Understand —

— for the TEI PAD.

Roger. The TEI 8 PAD, SPS/G&N: 45701, minus 040, plus 157 085:18:19.04. Are you with me so far? Over.

Roger.

Okay. Plus 3195, minus 01267, plus 04716 179 008 001, not applicable, plus 00187 33552 311 33355 42 0909 252. Are you still with me? Over.

Roger.

Okay. Picking up with the boresight star, it's old Dzuba who is the center star in the head of Scorpio; he's down 060, left 42, plus 0773, minus 16500 12982 36256 146:46:18. North set stars remain Sirius, Rigel, roll 129, pitch 155, yaw 010; four-quad ullage of 15 seconds, horizon on a 4-degree line at TIG, and requesting you zero the optics. Over.
