Spacelog Apollo 8

When we get the PAD data, we'll get it all out here.

Yes. We'll be sending the PAD data up to you in about another 2 hours, Frank; about 132 hours GET.

Okay. We—this will be the last set of star sightings we do now nominally, and even if we lose COMM, we'll just come on in with what we got.

Okay, Frank.

Incidentally, that COMM has been fantastic. I don't know how you've heard us, but boy, it's just like you are next door even in lunar distances.

Yes. It has really been great with rare exceptions when you are on a bad OMNI right before you switch. Then we get an awful lot of background noise, but in general, it has been excellent, and boy, we are really thankful for it because reading all these updates would be bad news with bad COMM, as you know.

Right.

Say, Mike, have you noticed the confidence the Captain has in his navigator?

He hasn't called you Goldfinger yet.

No. He is disregarding anything I can do. We're coming in anyway.

I suspect he is right on that point.

Well, back to the drawing board.

As usual, we are all a little pooped. I've got Bill sleeping now, and then Jim and I will swap just as soon as we get through with these stars.

Well, you're sounding real good, and you are doing good work.

Apollo 8, Houston.

Go ahead, Houston. Apollo 8.

Roger, Frank. If you get a chance to, we'd like for you to read us down your trunnion calibration number. We missed that one on the downlink, and we have an update for your passive thermal control attitude.

Okay. The trunnion calibrations were all zeros.

Roger. Thank you, and on page 2-104 the PTC attitudes should read zero pitch and 45 degrees yaw. Over.

Zero pitch and 45 degrees at 2-104.

Roger. And we'd like some PRD readings for those of you who are up and around.

Zero pitch, 45 yaw, it is?

Roger. Thank you.

I'm asking. I wasn't sure I copied it right.

Yes. That's affirmative, Frank. Zero pitch, 45 degrees yaw.

My PRD now reads 2.85.

Apollo 8, Houston. Radio check. Over.

This is 8. Loud and clear. How us?

Roger. You're loud and clear, Jim. We'd like to get your PRD reading while we've got you up and a flight plan change we're suggesting on page 2-107 when you're ready to copy.

Roger. Stand by.

I'm the only person up, and my PRD is reading 0.15.

Roger. I understand; 0.15.

And I'll bet that Bill's is still reading 0.64.

That's okay; don't bother him with it. He's asleep.

Okay. Go ahead with your flight plan change.

Houston, Apollo 8. Go ahead with your flight plan change.

Okay, Jim. On page 2-107, we're recommending that you delete that P52 and just-stay in PTC attitude. Your platform is real good, and we don't feel that alignment's necessary. One is coming up again at 139 hours anyway. And also, on that same page, we'd like to delete the “begin cabin cold soak.” Over.

Righto. Will delete the “begin cabin cold soak,” and we'll delete the P52.

Houston, Apollo 8. Over.

Roger, Apollo 8. This is Houston. Over.

Roger. Mike. Are you still planning to send up these updates at 132 hours?

Yes; affirmative, Jim. We're getting them together now.

Roger.

Apollo 8, this is Houston. Would you please go to P00 and ACCEPT, Jim, and we'll send you a P27.

We're ready for you.

Okay. Sending up a state vector to LM slot.

Go ahead, Houston.

Roger, Jim. You can go back to BLOCK; we got the P27 in and verified. It was a state vector update to the LM slot, and I'm standing by for the midcourse correction number 7 and the entry PAD at your convenience. Over.

Roger. Stand by.

Go ahead with midcourse number 7.

Okay. Midcourse correction number 7, RCS/G&N: 31600, not applicable, not applicable, 144:45:57.99, minus 00014, plus five zeros, plus 00001. Are you with me so far? Over.

Roger. With you.

Good. 000 304 000, not applicable, 000 191 00014 004 00014 450 —

Hey, Mike, hold it. Hold it, Mike.

Okay. Holding.

You said not applicable for HA and HP; I started to copy it down, and then I didn't get the right number sequence. Did you skip down to what, V_T?

No. Let's go back to apogee is not applicable, and then I just started reading the numbers again. From there, I've got a perigee and then a DELTA-V_T and then a burn time and so forth. Over.

Okay. I didn't hear a plus or minus on the HP, and I only got four numbers off of it. So could you start with HP again?

Okay. Going back to apogee, not applicable; perigee, plus 00191. And you weren't hearing things; it was my mistake. Over.

Roger.

Roger. Midcourse number 7 RCS/G&N: 31600, not applicable, not applicable, 144:45:57.99. Are you with me?

I'm with you.

Minus 00014, plus all zeros, plus 00001 000 304 000, not applicable, plus 00191 00014 004 00014 45 0459 225 Shaula, up 236 000, plus 0813, minus 16503 12202 36301 146:46:41, Sirius, Rigel, 308 209 357, HP, and P30 is 22.2 nautical miles.

That's all correct, Jim, and I have the entry PAD at your convenience.

Roger. Stand by one.

Ready to copy. Mike.

Right, Mike. Stand by.

Entry as follows: mid-Pacific, 357 152 359 146:29:13 268, plus 0813, minus 165 03 068 36221 651 12202 36301 146:46:13 0028, NA 4 times, with TO 400 0207 0025 0333 0816 16 0590 312, Zeta Persei, up 165, right 34, up. And remarks: use nonexit EMS pattern. And Zeta Persei is between Mirfak and Aldebaran, and Frank can never find it anyway.

Okay. That's all correct.

We certainly don't waste much time getting down to drogue deploy, do we?

Apollo 8, Houston. Over.

Go ahead, Houston.

Roger, Jim. In your computer, we'd like to do an erasable memory dump again, like we did the other day, and the reason we'd like to do it is, when you did that P37 about 8 hours ago, and you remember you put that EI time for TIG and got that P00 do thing; we'd like to—We don't think there's anything in the world wrong with it. We think everything is just perfect inside the computer, but we'd like to do an erasable dump as we did the other day; go through it bit by bit. Give us something to do down here. Over.

Okay. Any time.

And I have the procedures for you when you're ready to copy.

Go ahead.

Okay. VERB 01 NOUN 01 ENTER, 333 ENTER, and then read out register 1, and that register 1 should be 10 000. And then if it's not, I can give you procedures for getting it to 10 000. If it is 10 000 as we expect, then VERB 74 ENTER, and that will do the dump. Over.

Roger. When do you want it?

And, Apollo 8, you can do the first part of that now at your convenience to verify that register 1 is reading 10 000, but would you hold up on the dump itself until we get our ground stations configured, please. Over.

Will do.

Jim, we're getting noisy down here. Could you switch OMNI antennas, please?

Thank you, sir.

That works pretty well, doesn't it?

Not bad. I was amazed at the communication at the moon, too.

Apollo 8, Houston. We're configured for the dump. VERB 74 ENTER at your convenience.

Roger.

Apollo 8, Houston. The dump is complete, and it's your computer. Thank you.

Houston, Apollo 8. Over.

Apollo 8, Houston.

Apollo 8, this is Houston. Over.

Good morning, Mike. We had a little change of the guard here.
