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)

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.

Bill Anders (LMP)

If I see any water floating around, I'll give you another call.

Ken Mattingly (CAPCOM)

Roger. Thank you.

Ken Mattingly (CAPCOM)

Apollo 8, Houston. Radio check.

Ken Mattingly (CAPCOM)

Apollo 8, Apollo 8. Radio check.

Jim Lovell (CMP)

Read you loud and clear.

Ken Mattingly (CAPCOM)

Roger. We had a momentary loss of COMM on the ground then. Read you loud and clear.

Frank Borman (CDR)

Houston, Apollo 8. Did you call?

Ken Mattingly (CAPCOM)

Apollo 8, Houston. You are loud and clear. We've taken a look at this water —

Ken Mattingly (CAPCOM)

Apollo 8, Apollo 8, Houston. Read you loud and clear. We have taken a look at your potable water quantity problem, and it appears to be a transducer problem. Suggest that you leave the potable tank isolated. You have sufficient water in the waste tank to continue the entry. Over.

Frank Borman (CDR)

Roger. Thank you, Houston.

Bill Anders (LMP)

Does that mean we're GO for entry?

Ken Mattingly (CAPCOM)

Apollo 8, Apollo 8, go ahead.

Frank Borman (CDR)

Roger. Is our thermal stability good enough we can leave the PTC attitude and go to entry gimbal angles now?

Frank Borman (CDR)

Houston, how do you read? Apollo 8.

Ken Mattingly (CAPCOM)

Read you loud and clear, Apollo 8, and we're checking on the PTC problem now.

Ken Mattingly (CAPCOM)

Apollo 8, Houston. You are cleared with entry attitude at this time.

Frank Borman (CDR)

Okay. Fine. Thank you.

Ken Mattingly (CAPCOM)

Houston voice. Go to voice 925.

Bill Anders (LMP)

Houston, Apollo 8. Over.

Ken Mattingly (CAPCOM)

Apollo 8, loud and clear. Go.

Ken Mattingly (CAPCOM)

Apollo 8, Apollo 8, go ahead.

Bill Anders (LMP)

Roger. We have completed the checklist down to the 1-hour point, and we'll stand by for 1 hour.

Ken Mattingly (CAPCOM)

Apollo 8, Apollo 8, Houston.

Ken Mattingly (CAPCOM)

Just for information, did you folks end up having to use any command module RCS heaters?

Frank Borman (CDR)

Negative. All our indicators are pegged either high or at 5 volt.

CommTech

Carnarvon, network GOSS conference voice check. How do you read?

CommTech

Network, Carnarvon. Read you weak but clear.

CommTech

Roger, Carnarvon. I read you loud and clear.

CommTech

You are loud and clear now. Thank you.

Ken Mattingly (CAPCOM)

Apollo 8, Houston. Stand by for hand over to Carnarvon.

Ken Mattingly (CAPCOM)

Okay, Apollo 8. If you will go to P00 and ACCEPT, we would like to update your LM and CSM state vectors. Over.

Ken Mattingly (CAPCOM)

Apollo 8, Houston. State vector load is complete. Verify the computer is yours.

Ken Mattingly (CAPCOM)

Apollo 8, Apollo 8, Houston. State vector load is complete; the computer is yours.

Frank Borman (CDR)

Roger, Houston. We are going to BLOCK.

Ken Mattingly (CAPCOM)

Okay. Two fast items: number one, it has been suggested that since Marezine takes some time to take effect, you might consider whether you would be interested in taking some now. And I have an entry PAD which has some very small updates to go on it if you would like to copy that.

Frank Borman (CDR)

Okay. Stand by. Let me get out the entry PAD.
