Spacelog Apollo 8

There is a crater Taruntius, I believe, over there.

We will try to get TV on this at a later time, when we are not getting ready for a burn.

Roger, Jim.

I can see the old second bishop right now, Mount Marilyn.

Roger.

Houston, at these sun angles, everything is quite distinct; shadows are good; the ground doesn't have any sunlight returned. It appears very good visibility at these sun angles.

Roger.

As a matter of fact, Bill just mentioned that the visibility seems to be excellent just about up to the terminator. It's something which I didn't expect. I thought there would be a little bit more gradual shift to darkness, but it's very sharp and distinct.

Roger, Jim.

Of course, we are in a very high phase angle now.

Apollo 8, Houston. All of your updates are in; the computer is yours. Over.

Thank you.

The update block.

Roger. Break. Apollo 8, Houston. Your TEI 2 PAD is good; stand by to copy your TEI 3. Over.

Apollo 8, Houston. Roger. I made one mistake; horizon window is minus 1 degree. Over.

Minus 1 degree.

Roger. Readback is correct.

Apollo 8, this is Houston. You are GO across the board for LOI 2. Would like to take the DSE for a dump. Over.

Roger. You got it. I understand we are GO for LOI 2.

That's affirmative.

Before you take the DSE for a dump, let me give you a quick—let me give you a quick rundown on the DSE before you dump it, if you will.

Roger. Standing by.

Roger.

Okay, Houston. You've got the tape.

Apollo 8, Houston. Roger.

Apollo 8, Houston. Would you believe that Taurus, Aida is Pleaides? Over.

Have you got that tape dumped, Houston? We're about to lose the high gainer.

Apollo 8, Houston. We're dumping now—looks like we'll be 5 or 10 more minutes.

Try to get it dumped, and I'll play it, rewind it if necessary -

Roger. Copy.

TEI 4.

Alright. This is the TEI 4 update: SPS/G&N 45695, minus 053, plus 141. Are you with me so far? Over.

So far.

Very good. 077:21:27.58, plus 30627, minus 00625, plus 00577 180 018 001, not applicable, plus 00188 30639 256 30452. Are you with me so far? Over.

So far seems … hold it a minute though, will you?

Okay. Go ahead.

Okay. The last number I gave was DELTA-V_C. Picking up at the sextant star: 40 2730 396 033, down 030, left 19. Are you with me? Over.

Roger.

Okay. Plus 0858, minus 16500 12960 36195 146:37:21; comments: north set of stars Sirius and Rigel, roll 129, pitch 155, yaw 010, ullage two quad, 20 seconds, two-zero seconds from quads Bravo and Delta; horizon on 2-degree line at tine of ignition minus 3 minutes. Over.

That's about the size of it, Frank, and a map update for REV's 3/4 when you are ready.

Ready.

REV's 3/4: LOS 75:01:23, sunrise 75:10:16, prime meridian 75:17:16, AOS 75:47:18, sunset 76:23:11; remarks: subsolar point 75:46:55, IP-1 acquisition 76:11:17, IP-2 acquisition 76:12:30. For IP-1 and 2, those ACQ times are for shaft and trunnion angles equals zero. Over.

Roger. Thank you. 75:01:23 75:10:16 75:17:16 75:47:18 76:23:11, subsolar 75:46:55, IP-1 76:11:17, IP-2 76:12:30, and at shaft and trunnion at 0.

Apollo 8, Houston.

Go ahead, Houston.

Roger. When Bill gets a minute, we'd like to get battery B started charging. Over.

Apollo 8, Houston.

Go.

Roger. For Bill—the voice quality on the backside DSE is extremely poor. We consider it unusable, and we recommend that all pertinent comments be hand recorded so we don't lose them. We should not count on using the tape at low bit rate for voice.

Okay, Houston. We're getting so busy that we are having a hard time trying to do a neat job of logging. I'll try to do it on the flight plan; and if I make any visual observations, we'll put them on the DSE, and I'll try to scribble some notes here and there.

Roger. Understand. Now high bit rate is working great.

Roger.

Hey, Houston, Apollo 8.

Apollo 8, Houston. Over.

How about giving us the TV times for the ninth REV, will you please?

Yes, we sure will, Frank. Stand by.

Apollo 8, Houston.

Go ahead.

Roger. We were checking into precise start and stop times for TV, and you are GO for the next REV. Over.

I understand; go for the next REV. Mike, we'd like to, if we could, time the TV to a passing over the terminator. We would like to track the terminator with the TV; think that's the most impressive thing we've seen, and that might be the best thing rather than trying to acquire the earth.

Okay, Frank. That's one of the things we are looking at right now. We have you ending at about 86 hours, and we're looking at extending that few minutes to include that terminator view. Over.

Okay. I don't want us to run into REV 10 very much at all, though.

Roger. Understand.

Houston; Apollo 8.

Go ahead, Apollo 8.

Apollo 8, Houston.

… since the DSE qual is not so good. How do you read, Mike?

I read you loud and clear. You were cut out about the DSE. Say again.

Roger. Since the qual isn't so good, let me give you a quick rundown of the status of photo targets. You ready to copy?

Ready to copy.

Okay. At REV 1, we got photo target 90 and terminator photography south for near-side terminator. Starting on REV 2, we've got target 12 and targets 10, 14, 16, 19, 20, 21, and 23. Unfortunately, we got into a high—I got into the high-speed film there somewhere, and I think those 250mm targets were on high speed. We did change film, and starting out in Tex—Crater, Texas, with target 28, 31, 40, 36, plus several targets of opportunity that were recorded on the DSE, but apparently lost. Have you been able to copy?

Yes, I'm with you, Bill. Keep going.

Okay. I might be calling up too fast. Okay. On the third REV, we got target 58 and 63 and 65. The training photography was accomplished, and it was done on magazine D, which now has—correction, that's magazine E—which now shows 95 exposures. Magazine D is fresh. Magazine K was also used for training photography, and it's showing 0.51.

Roger. We copy all that, Bill.

Apollo 8, Houston.

… Mike, this is Frank again.
