Bill Anders (LMP)

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

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.

Jim Lovell (CMP)

Okay. Go ahead with the entry PAD, Houston.

Ken Mattingly (CAPCOM)

Okay. We are still going to the mid-Pacific, 357 152 359 146:29:13 267, plus 0813, minus 16503 066 36221 647 12166 36301 146:46:13 0028, the next block is November Alfa, V0 400 0210 0025 0335 0816 160590 312; Zeta Persei, up 165, right 34, up nonexit EMS pattern; Sirius and Rigel, roll 308, pitch 209, yaw 357, no P65 involved. Over.

Jim Lovell (CMP)

Roger, Houston. Entry PAD as follows: mid-Pacific, 357 152 359 146:29:13 267, plus 0813, minus 16503 066 36221 647 12166 36301 146:46:13 0028, NA, 400 0210 0025 0335 0816 160590 312, Zeta Persei, up 165, right 34, up. Use nonexit EMS pattern; Sirius, Rigel, 308, 209, 357, no P65.

Ken Mattingly (CAPCOM)

That's correct, Apollo 8.

Ken Mattingly (CAPCOM)

Apollo 8, Houston. You are clear to initiate cabin coldsoak at your discretion. Over.

Jim Lovell (CMP)

Roger, Houston. We're starting that now.

Frank Borman (CDR)

You have a hot mike, Houston.

Bill Anders (LMP)

Houston, Apollo 8. Over.

Bill Anders (LMP)

Okay. It doesn't appear that we are going to be able to trigger the primary evaps, so I'm going to go ahead and start up the secondary loop.

Ken Mattingly (CAPCOM)

Okay, Apollo 8. We concur.

Ken Mattingly (CAPCOM)

Apollo 8, Apollo 8, go ahead.

Frank Borman (CDR)

Roger. Since we're going as smoothly as we are here—we've got good COMM—let's start this pyro circuit check about 10 minutes early. What do you say?

Ken Mattingly (CAPCOM)

Apollo 8, Apollo 8. We can conduct the pyro check just any time.

Frank Borman (CDR)

All right. Why don't we do it here just momentarily then?

Frank Borman (CDR)

We'll give you a call when we're ready.

Frank Borman (CDR)

Houston, we are ready to proceed with the pyro circuit check.

Frank Borman (CDR)

MSFN, are you monitoring the sequential test now?

Ken Mattingly (CAPCOM)

Apollo 8, Apollo 8. That's affirmative.

Frank Borman (CDR)

Hello, Houston. Apollo 8.

Ken Mattingly (CAPCOM)

Apollo 8, Apollo 8. Loud and clear. Affirmative we are monitoring.

Bill Anders (LMP)

Standing by for GO and PYRO ARM.

Ken Mattingly (CAPCOM)

Apollo 8, Apollo 8. You have a GO.

Frank Borman (CDR)

Houston, this is Apollo 8; How is your tracking looking?

Frank Borman (CDR)

Okay. Everything went fine with the check. We are all armed and ready to go here.

Ken Mattingly (CAPCOM)

Okay. If you have done everything else, how about let's make a VHF check.

Frank Borman (CDR)

Okay. I'll turn off my S-band; the other two will be on S-band.

Ken Mattingly (CAPCOM)

Roger. I'll give you a count in just a second.

Ken Mattingly (CAPCOM)

Apollo 8, Houston. Simultaneous VHF and S-band. Over.

Frank Borman (CDR)

Roger. I'm not reading you on VHF.

Ken Mattingly (CAPCOM)

Apollo 8, Houston. Simultaneous VHF and S-band. Do you verify that you are on the left hand VHF antenna? Over.

Bill Anders (LMP)

We can verify the antenna, but we can't verify reading you on S-band or on VHF.

Ken Mattingly (CAPCOM)

Okay. We are receiving some downlink, although it is considered to be poor quality.

Ken Mattingly (CAPCOM)

Apollo 8, Houston. We'd like to try the right VHF antenna, if you have time.

Bill Anders (LMP)

We're—we're on right, Ken.

Ken Mattingly (CAPCOM)

Okay. This is a simultaneous VHF and S-band transmission: one, two, three, four, five. How do you read on VHF? Over.

Frank Borman (CDR)

Read you loud and clear.

Ken Mattingly (CAPCOM)

Understand that's on VHF. Is that affirm?
