Spacelog Apollo 8

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

Apollo 8, Houston. Radio check.

Apollo 8, Apollo 8. Radio check.

Read you loud and clear.

Apollo 8, Houston.

Houston, Apollo 8. Did you call?

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

Houston, Apollo 8.

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.

Roger. Thank you, Houston.

Does that mean we're GO for entry?

Houston, Apollo 8.

Apollo 8, Apollo 8, go ahead.

Houston, how do you read? Apollo 8.

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

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

Houston, Apollo 8. Over.

Apollo 8, loud and clear. Go.

Apollo 8, Apollo 8, go ahead.

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

Roger.

Apollo 8, Apollo 8, Houston.

Go ahead, Houston.

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

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

Okay. Thank you.

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

Network, Carnarvon. Read you weak but clear.

Roger, Carnarvon. I read you loud and clear.

You are loud and clear now. Thank you.

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

Apollo 8, Houston.

Go ahead.

Go ahead, Houston.

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

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

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

Roger, Houston. We are going to BLOCK.

Apollo 8, Houston.

Go ahead, Houston.

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.

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.

That's correct, Apollo 8.

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

… your mike is stuck.

You have a hot mike, Houston.

Houston, Apollo 8. Over.

Go ahead, 8.

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.

Houston, Apollo 8.

Go ahead, 8.

Apollo 8, Apollo 8, go ahead.

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?

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

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

Roger.

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

Roger.

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

MSFN, are you monitoring the sequential test now?

Houston, Apollo 8.

Apollo 8, Apollo 8. That's affirmative.

Hello, Houston. Apollo 8.

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

Okay.

Standing by for GO and PYRO ARM.

Apollo 8, Apollo 8. You have a GO.

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

Looking great.

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

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

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

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

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

Roger. I'm not reading you on VHF.

Roger. Stand by one.

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

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

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

We're—we're on right, Ken.

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

Read you loud and clear.

Understand that's on VHF. Is that affirm?
