Ken Mattingly (CAPCOM)

Okay, Apollo 8. We would like to update your LM state vector, CSM state vector, and target point. If it is convenient now, why, we will go ahead and do that if you will go to P00 and ACCEPT.

Bill Anders (LMP)

Roger. P00 and ACCEPT.

Frank Borman (CDR)

Go ahead, Houston. Apollo 8.

Ken Mattingly (CAPCOM)

Okay. The loads are in and verified, and the computer is yours.

Ken Mattingly (CAPCOM)

You can take it back to BLOCK, and for Bill's information, latest guess from the main bus post-SEP voltage to 27.5

Bill Anders (LMP)

Guess! You mean the EECOM's are guessing?

Bill Anders (LMP)

At least, they are honest for a change.

Ken Mattingly (CAPCOM)

That is more than you can say for the computers.

Bill Anders (LMP)

Go ahead, Houston. Apollo 8.

Ken Mattingly (CAPCOM)

Okay, 8. We have an entry PAD for you.

Bill Anders (LMP)

Ready to copy, Houston.

Ken Mattingly (CAPCOM)

Okay. This will be the mid-Pacific, 357 152 359 146:29:00 268, plus 0813, minus 16503 065 36221 645 12122 36301 146:46:14 0028. The next block is November Alfa: D0 400 02 12 0025 0334 08 14 16 0590 312; Zeta Persei, up 165, right 34, up. Use nonexit EMS pattern, GDC align; primary star Sirius, secondary Rigel, roll 308, pitch 209, yaw 357; this entry will not involve P65. Over.

Jim Lovell (CMP)

Houston, Apollo 8. Entry PAD as follows: mid-Pacific, 357 152 359 146:29:30 268 plus 0813 minus 16503 065 36221 645 12122 36301 146:46:14 0028, next block not applicable, 400 0212 0025 0334 0814 16059 312, Zeta Persei, up 165, right 35 up, use nonexit EMS pattern, backup alignment; Sirius, Rigel, roll 308, pitch 209, yaw 357, and we won't need P65.

Ken Mattingly (CAPCOM)

Okay, Apollo 8. I would like to verify sextant star shaft 0590, and the boresight star.

Ken Mattingly (CAPCOM)

The last one is right 34. Over.

Jim Lovell (CMP)

Roger. Boresight star is right 34. And I have the sextant shaft; that's 0590.

Ken Mattingly (CAPCOM)

That's correct, Apollo 8.

Ken Mattingly (CAPCOM)

Apollo 8, Apollo 8, Houston.

Ken Mattingly (CAPCOM)

Okay, Apollo 8. Can you tell us if you've done anything with your potable water? We've noticed our readout has gone from 100 percent down to 56 in the last couple of minutes.

Jim Lovell (CMP)

We're reading about 50 percent right now.

Ken Mattingly (CAPCOM)

Roger. That correlates with what we see. Have you done anything to change configuration? Over.

Jim Lovell (CMP)

Yes, we noticed the venting here, too, Houston.

Ken Mattingly (CAPCOM)

Jim, did you mean you could visually see it?

Jim Lovell (CMP)

Yes, we're—oh, stand by, Ken. Bill just dumped urine, so that might have been urine we were seeing.

Jim Lovell (CMP)

Bill just shut the potable inlet, Ken.

Ken Mattingly (CAPCOM)

Apollo 8, Apollo 8, go ahead.

Jim Lovell (CMP)

Roger, Houston. We're still showing about 52 percent, and we had our switch on waste so we don't know whether it dropped from a higher value or not. Has yours been stabilized now?

Ken Mattingly (CAPCOM)

That's affirmative; ours has stabilized now. It was reading full just a few minutes ago.

Jim Lovell (CMP)

Roger. I don't think—we can't account for any sudden drop in water.

Ken Mattingly (CAPCOM)

Okay. We looked in the malfunction procedures, and number 28 doesn't reveal anything very startling.

Jim Lovell (CMP)

Bill is looking there now.

Bill Anders (LMP)

Houston, Apollo 8. Over.

Bill Anders (LMP)

Okay. I'm looking at malfunction 28, and it takes you to box 6, but I don't really think that's the problem because the waste tank quantity hasn't changed any. Over.

Ken Mattingly (CAPCOM)

Okay. I concur. We're watching the same thing.

Bill Anders (LMP)

Look, we don't care about the potable tank, but we do about the waste tank, so just in case there is a problem somewhere, I'm going to shut the potable tank off and leave the waste tank inlet valve open. How does that sound to you?

Ken Mattingly (CAPCOM)

Stand by. Okay, 8. We concur.
