Spacelog Apollo 8

Apollo 8, Houston. Thank you for the look.

Roger.

Apollo 8, this is Houston. You have the DSE.

Thank you, Houston.

Roger. Apollo 8, on your backside data, it's pretty much unintelligible. We suggest, Bill, that you recheck the position of your mike for your backside pass and try to speak a little bit louder and more distinctly. The last one we listened to, was pretty much unintelligible. Over.

Roger. As soon as we get squared away, we will give you a real quick real time summary.

Roger.

And, Houston, you might let us know, can we do the red/blue filter exercise with both these filters—red filters on? Over.

Stand by.

Apollo 8, this is Houston. Apollo 8, Houston. Negative.

Apollo 8, this is Houston with an LOI 2 maneuver PAD. Ready to copy?

Stand by.

Houston. Standing by.

Okay, Houston. Go ahead.

Apollo 8, this is Houston. LOI 2, SPS/G&N: 46427, minus 053, plus 141 073:35:05.70 minus 01350, plus all zeros, plus all zeros. Copy?

Roger. Taurus, Aida; I repeat, Taurus, Aida. Up 162, left 01, the remainder not applicable. GDC align Sirius, Rigel 129, 155, 010, negative ullage, horizon window ignition minus 3 27 degrees, horizon left. At ignition, 18 degrees, horizon left; before readback, configure for receiving any update. Over.

Roger. Understand. Configure for receiving an update.

Okay. We're in P00 and ACCEPT. Go ahead.

Roger. I'm ready for your readback.

LOI 2, SPS/G&N: 46427, minus 053, plus 141 073:35:05.70, minus 01350, plus 0000, plus 0000 000 175 358 00607, plus 00606 01350 009 01265 02 3112 197; Taurus, Aida, up 16.2, left 0.1, fixed read not applicable; Sirius, Rigel 129 155 010, no ullage, ignition minus 3 27 degrees, ignition 18 degrees.

Apollo 8, Houston. Roger. Readback is correct.

Apollo 8, this is Houston. Your map update for REV 2/3, no change. Over.

Understand. No change, REV 2/3.

Roger, Frank. You can expect GO/NO-GO for the next rev at 20 minutes before LOS. Over.

Roger.

Apollo 8, this is Houston. We'll try to make that call 20 minutes before every LOS. Over.

Fine.

Apollo 8, Houston. We have the CSM vector in starting on the LV. Over.

Thank you.

Houston, this is Apollo 8.

Apollo 8, Houston. Go.

Roger. Just an interesting feature: on my center window which has ice on it, it is now beginning to melt. I'm beginning to see through it.

Roger. That's good news.

And again we're directly over our favorites, Messier and Pickering.

The view at this altitude, Houston, is tremendous. There is no trouble picking out features that we learned on the map.

Roger. Jim, that's good news. What do you think of the lighting situation as far as the range of lighting for good visibility?

The range from here is outstanding. I wish we had the TV still going because the brown area now is darker. We have just passed over the Sea of Fertility, and the mare is darker. The mountain range has got more contrast, has more contrast because of the sun angle. Bill's got the 16 mm going for us.

Roger.

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.

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?

Go ahead—or Houston, this is Apollo 8. TEI 3 with 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.

Apollo 8, Houston. Over.

Apollo 8, Houston. Over.

Apollo 8, Houston. Over.

Roger. Go ahead, Houston. Apollo 8.

Apollo 8, this is Houston. DSE is rewound, and it's yours—available for use is about 1 hour of low bit rate and 2 minutes of high bit rate for your burn, without running over your good data. Over.

Roger. Do you read us now, Houston?

Roger. Reading you loud and clear now.

Okay.

Apollo. 8, this is Houston. You are GO for LOI 2 on the next rev. Over.

I can understand GO for LOI 2 on the next rev.

How do you read, Houston?

Apollo 8, this is Houston. Reading you loud and clear. How me?

Loud and clear.
