Spacelog Apollo 8

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.

Ready for TEI 3.

Roger. TEI 3. SPS/G&N 46427, minus 053, plus 141 075:31:29.95, plus 28960, minus 00456, plus 00720. Copy?

Roger. SPS/G&N—this is for TEI 3—46427, minus 053, plus 141 075:31:29.95, plus 28960, minus 00456, plus 00720 180 021 002, NA, plus 00188 28972 251 28793 40 2769 396 033 0000, left 17, plus 00883, minus 16500 12955 36185 146:35:07; Sirius, Rigel 129, 155, 01, two jet, 20 seconds, B and D, horizon 2 degrees at ignition minus 3 minutes, assumes no LOI 2.

Apollo 8, Houston. Readback is correct.

Apollo 8, this is Houston with a TEI 3—with an LOI 2. Over.

Go ahead.

Roger. TEI 3: SPS/G&N 45810, minus 053, plus 141 075:21:28.46, plus 30128, minus 00540, plus 01911. 180 019 001. Copy?

Go ahead—or Houston, this is Apollo 8. TEI 3 with LOI 2. SPS/G&N 45810, minus 053, plus 141 075:21:28.46, plus 30128, minus 00540, plus 01911 180 019 001, NA plus 00188 30193 255 30008 40 2742 396 033, down 021, left 18, plus 0888, minus 16500 12955 36185 146:34:50; no change, no change 1 degree in the rise of ignition minus three, assumes LOI 2.

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.

We are about to lose it, Houston. How far are you on the tape dump?

Apollo 8, this is Houston. It looks like we have lost it. They weren't quite done. We are standing by for a countdown to BIOMED switch left. Over.

Roger.

Look, we would like to get it dumped if we could. Standby a second.

Okay.

Did you get it stopped?

Bill, you can go ahead and turn it off.

Okay. We are not going to have a high gain now until the next time around. Can you give me some idea of how much of that pass you got.

Apollo 8. this is Houston. We—negative. We can't tell. You can go ahead and turn it off.

Well, how long did you—did you dump it?

Roger. stand by; they are checking.

Apollo 8, Houston.

Go ahead Houston.

Apollo 8, this is Houston reading you with a great deal of noise in the background. Go ahead and rewind your tape and start it in low bit rate, and we will try to catch that dump at the end of the next rev.

Roger. I would like to have an idea on how much you dumped. So I know whether … all these things or whether we have better setting in.

Roger. Stand by.

Apollo 8, Houston. We are working on that time. We should be able to tell you before LOS. Over.

Apollo 8, Houston. Over.

Go ahead.

Roger. Did you read my last?

That is affirmative. You will give us a run-down when you figure out how much tape you dumped.

Houston, Apollo 8.

Apollo 8, Houston. Go.

Roger. What REFSMMAT are we using for this LOI 2 burn?

Stand by, Frank. We're talking.

Okay. I notice an LOI 2 REFSMMAT. If it is, I don't understand why the pitch is 175.

Apollo 8, Houston.

Go ahead.

Apollo 8, this is Houston. You are right; the REFSMMAT is LOI 2. The REFSMMAT was determined out there before the last midcourse correction, and since that time, there has been a slight change of trajectory, and the point at which you are burning LOI 2 now is just a shade different than where it was originally planned. Over.

Apollo 8, Houston.

Apollo 8, Houston. Over.

Apollo 8, Houston. Over.

Apollo 8, Houston. Over.

Apollo 8, Houston. Over.

Apollo 8, Houston. Over.
