Spacelog Apollo 8

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.
