Spacelog Apollo 8

Loud and clear.

Apollo 8, we would like to —

— TEI 10.

Apollo 8, we would like to have you go to P00 and ACCEPT and we would like to take the recorder at this time; then I will copy your PAD.

You have got P00 and ACCEPT, and you have the recorder.

Thank you, Jim.

All set for the maneuver.

Go ahead.

TEI 10, SPS/G&N: 45597, minus 040, plus 157 089:19:15.67, plus 35186, minus 01512, minus 00520 180 007 000, not applicable, plus 00186 35223 318 35018 42 0924 253; Scorpii Delta, down 069, left 45, plus 0748, minus 16500 12994 36300 146:50:05; Sirius, Rigel, 129 155 010; four-quad, ullage, 15 seconds; horizon on the 3.2-degree mark is T minus 3; high-speed procedure minus MA.

That is correct, Apollo 8. Would like to confirm the hours on GETI, 089.

Roger. 089.

Alright, Apollo 8. I have TEI 11 PAD;

We are ready; go ahead.

Roger, Houston. TEI minus 11, SPS/G&N: 45597, minus 040, plus 157 091:18:12.24, plus 36325, minus 01727, plus 01428 180 003 000, not applicable, plus 00186 36394 323 36186 42 0995 254; Scorpii Delta, down 103, left 48, plus 0742, minus 16500 13005 36327 146:51:44; Sirius, Rigel, 129 155 010; four quads, 15 seconds, 2.9-degree window mark at T minus 2; high-speed procedure minus MA.

That's correct, Apollo 8.

Houston, could you give me the SPS helium tank temperature at about 87:20, please?

Okay. Stand by one.

Apollo 8, Houston. Our loads are in and verified; the computer is yours.

Roger.

Houston, Apollo 8.

Apollo 8, Houston. At 87:48, we're reading 84 degrees, and at LOS we had 80. We'll take a look at the tape and see if we can find out what we had on the backside.

Okay. I would kind of like to know what I might expect at ignition here at TEI.

Roger. We'll take that off the tape.

Houston; this is 8. I take it you have loaded both state vectors; is that correct?

That's affirmative.

Roger.

We loaded your CSM and LM NAV and external DELTA-V, in that order.

Apollo 8, Houston.

Go ahead, Houston. Apollo 8.

Okay, Apollo 8. We've reviewed all your systems. You have a GO for TEI. One of the things we would like to do as soon as you come out on the other side is a P23. We are checking into your helium pressures now. We're going to correlate not only the last REV but the previous REV for the same location, and we will have that number for you in a little bit.

Apollo 8, Houston. The tape recorder is yours. I have your PTC attitude.

Roger. Go ahead.

Is that pitch 10 and yaw 45?

Affirmative. And looks like that will go with the entry REFSMMAT; begins at 92 hours.

Thank you.

Apollo 8, would you put your UP TELEMETRY to BLOCK, please?

Apollo 8, Houston.

Go ahead.

Okay. On the helium tank TEMP's: that's not recorded on low bit rate, and looking over our tape dumps, most of this stuff we have on the backside there is low bit rate. So we won't be able to give you an exact number, but looking at what we have every time we go out of sight and come back over the hill, it looks like you can expect about 82 to 84 degrees as a nominal temperature.

Apollo 8, Houston. We'd like to have the tape recorder for about 5 minutes for one last look.

Roger, Houston. You're getting it.

Thank you. And I guess we still have a cryo stir ahead of us, and we've checked your triple bias, and there's no change.

Roger. And we're stirring cryos right now.
