Spacelog Apollo 8

Roger. I reserviced it, put it to AUTO—H₂O flow to AUTO; and the steam pressure went to zero again. So I tried reservicing it the second time for 1 minute, and again no results. I'm in the present process of closing the back pressure valve manually. Over.

Roger. Understand you tried to reservice it twice, both times steam pressure has gone to zero, and now you are closing the back pressure valve manually.

Roger. Each time I have reserviced it, the steam pressure came up to about 0.07 to 0.1; but as soon as the steam and water were put to AUTO, the steam pressure went right back down again.

Roger. We copy, and we are reading you loud and clear now, Bill. On your map update, did you copy that that I gave you previously?

Negative. We have not copied it yet.

Negative.

Okay. I have it for you again when you are ready to copy.

Ready to copy.

This is a map update for REV's 4/5: LOS 76:59:59, sunrise 77:09:06, prime meridian 77:15:47, AOS 77:45:50, sunset 78:22:03; remarks: IP-1, acquisition time for CP2 is 77:29:42, IP-1 time closest approach for target B-1 78:10:25. Over.

Roger. LOS 76:59:59, sunrise 77:09:06, 77:45:47, 77:45:50, 78:22:03; IP-1, CP2 77:29:42, IP-1 TCA for B-1 78:10:25.

That's right, and the prime meridian time is 77:15:47, and you got your computer back. We've got a good P27 update.

Okay. We will go to P00 and TRANSFER.

Roger.

Houston, do you have a TEI 5 for us?

We are working on it now, Frank. Have it for you momentarily.

Roger.

Apollo 8. Houston.

Go.

Roger. On your back pressure valve, we would like to know how long after you closed the back pressure valve the first time—how long it was from the time you closed it until the time you started the reservicing? We would like for you to wait about 15 minutes to prevent any ice from forming due to flash freezing. Over.

Okay. I started immediately to reservice it.

Apollo 8, Houston. We show that you closed it this last time about 4 minutes ago, so we would like you to wait another 15 minutes and then try to reservice it again at that time and then go to AUTO. Over.

Roger.

Roger. Thank you. The TEI 4 PAD which you have is still valid. We will have a TEI 5 PAD for you shortly.

Roger. Be advised we are presently in steam pressure MANUAL, and we're in H₂O flow AUTO, and are now in H₂O flow OFF, as of about 5 seconds ago.

Roger. We copy that, Bill. And we confirm that's a good configuration.

Right now, I've got the H₂ flow OFF. Do we stay that way?

Affirmative.

Apollo 8, Houston. On your television update, we propose that you start the TV at the flight plan time of 85 hours 37 minutes and simply extend the stop time a few minutes. You're currently scheduled to stop at 86 hours, and we would like to keep it going until the terminator, which should be approximately 86:14. Over.

Roger.

Frank, I know you are busy up there. We've got the daily news for you whenever and if ever you'd like to hear it.

I'll give you a call.

Apollo 8, this is Houston.

Go ahead.

I have the TEI 5 PAD for you whenever you are ready to copy.

Okay. Go ahead.

Okay. TEI 5, SPS/G&N: 47 correction—45701, minus 043, plus 116 079:21:26.03. Are you with me so far?

Roger.

Plus 31171, minus 00767, minus 00214 180 017 001, not applicable, plus 00188 31181 259 31003. Are you with me? Over.

Roger.

Roger. 40 2711 398 033, down 043, left 23, plus 0832 minus 16500 12956 36208 146:39:44; north set of stars remain Sirius and Rigel; roll, pitch, and yaw remain same angles: 129 155 010, ullage remains two quads for 20 seconds, quads B and D; horizon on 4-degree line at TIG minus 3 minutes. Over.

Roger. Here we go: TEI 5, SPS/G&N 45701, minus 043, plus 116 079:21:26.03, plus 31171, minus 00767, minus 00214 180 017 001, NA, plus 00188 31181 259 31003 40 2711 398 033, down 043, left 23, plus 0832, minus 16500, plus 12956 36208 146:39:44. Set stars are the same; ullage—we'd like—do you have any objection to using four quads for 15 seconds?

No objection to four-quad ullage, Apollo 8.

Okay. We'd like to just go ahead and use four quads all times, unless we get a lot shorter on fuel than we are now.

Understand.

And is that 15 seconds?

Affirmative: 15 seconds, four quads.

Apollo 8 —

Thank you, and horizon is 4 degrees at minus —

That readback is correct, Frank, and we'd like to advise that the voice quality on that high bit rate is excellent. Over.

Thank you. Mike, it's four quads for 15 seconds. Is that right?

That is affirmative, Apollo 8: four quads for 15 seconds.

Thank you.

Apollo 8, Houston.

Go ahead, Houston. Apollo 8.

Okay. You want us to reservice it now?

That's affirmative, and upon completion, go back to AUTO.

Apollo 8, Houston.

Go ahead, Houston.

Roger. We are still dumping your tapes. The voice quality on high bit is coming through superb, and you are GO for the next rev. And we would like to get a brief status report on your rest between 60 hours and LOI 1, just to fill in some information for us.

We only got a couple hours rest.

Okay.

We're tired right now, but we will have to wait until TEI before we get back to the regular cycle.

Alright. I suspect you're right.

Okay, Houston. The water boiler has been reserviced, back pressure valve CLOSED for 1 minute, water ON for 2, and it's now steam pressure AUTO, H₂O flow AUTO.

Roger. We copy, Bill.

If we have a problem, a similar problem, again on the back side in the sunlight, might be a good idea to crank the secondary loop until we have AOS. What do you think about that?

Stand by one, Bill.

Apollo 8, Houston.

Go ahead, Houston. Apollo 8.

Roger, Jim. In regard to your evaporator, we feel that if you do have a similar problem next time on the back side in sunlight, check the evaporator outlet temperature, and if it gets above 60, we concur that it would be a good idea to bring up the secondary loop. Over.

Roger.

Apollo 8, Houston. When we say bring up the secondary loop, we mean bring up the evaporator only on the secondary loop. Copy?

Roger.

Houston, Apollo 8. We got time for a little news?

Apollo 8, this is Houston. Over.

I say how about a little bit of that news you promised?

Roger. We got the Interstellar Times here, the December 24 edition. Your TV program was a big success. It was viewed this morning by most of the nations of your neighboring planet; the earth. It was carried live all over Europe, including even Moscow and East Berlin, also in Japan and all of North and Central America and parts of South America. We don't know yet how extensive the coverage was in Africa. Are you copying me all right? Over.

You are loud and clear.

Good. San Diego welcomed home today the Pueblo crew in a big ceremony. They had a pretty rough time of it in the Korean prison. Christmas cease-fire is in effect in Viet Nam, with only sporadic outbreaks of fighting. And if you haven't done your Christmas shopping by now, you better forget it.

Thank you.

A couple of Oilers made the All-Star team, Webster and Farr.

Roger.

And that's about all our news. How about your news?

Well, we'll be looking forward to a big burn here shortly.

Roger.

Mike, I think I can say it without contradiction, it's been a mighty long dry spell up here.

I guess you can say anything you like without contradiction.

When can we dump water, Houston?

Say again, Frank.

When can we dump water?

Stand by.

Apollo 8, Houston.

Go, Houston.

We will get you the number after a while on your water dump. It looks like the quantity isn't increasing very slightly, and we're considering not only the quantity in regard to the dump, but also its effects on the trajectory relative to TEI and so forth, but we will have a good answer for you shortly.

We are not just thinking about the waste water tank: we're thinking about some other kind of water that has to get dumped out of the spacecraft, slightly used water.

Apollo 8, Houston.

Go ahead.

Roger. We have about three and a half minutes to LOS. We give you back the DSE under your control, and in regard to your water dump, we are tentatively predicting a waste water tank dump at about 80 hours GET and any other dumps are at your discretion, any time you would like to make them.

Thank you.

People listening to the high bit rate down here say it's like sitting in your living room listening to good hi-fi.

Sounds like a good idea.

Apollo 8, Houston. Coming up on 2 minutes to LOS. We got a good reservice on the primary evaporator, and everything is still looking very good down here.

Okay. Thank you.

Apollo 8, Houston. One minute to LOS. Are you still reading us loud and clear?

Loud and clear. Loud and clear.

Okay, fine. We've been noticing a little bit of increase in our background noise as you approach backside.

Roger. We had to go off the high gain. That's why.

Roger.

Have a good backside; we'll see you next time around.

Apollo 8, this is Houston. Over.

Houston, Apollo 8. Go ahead.

Roger. Read you loud and clear. Welcome back.

Roger. Looks like the evaporator—looks like the evaporator is holding okay, or at least it is trying to. It dropped the temperature down to about 32, and now it's come back up again and stabilized at about 42 degrees.

Roger. Copy you, Bill.

Houston, Apollo 8.

Apollo 8, Houston.

Roger. Houston, this is Apollo 8. What we are doing on the control point tracking—I managed to look for a CP-1 at the same time we were trying to do a CP-2 on this rev. I picked up two marks which are just as small, but more easily recognizable, than the ones that were given to me. I know that I can repeat the process and pick the same small point on the next rev. Now I can try to look for the control points that are written down, but I think that I have better control over the ones that we have.

Roger, Jim. Understand. We'll check that for you.

Roger. One more point: the control point times which you have given me are a little bit off, and I can notice by comparing these maps that these maps are not too well aligned either.

Roger. These two small points that you can repeat your marks on: will you be able to identify those precisely on a map? Over.

That's affirmative; that is why I picked them. They are both—they're both very prominent features, and they are both very small craters about the same size as the ones we are looking for, but I can pinpoint them on a map.

Roger.

Houston, Apollo 8.
