Jerry Carr (CAPCOM)

Apollo 8, this is Houston. At 68:04, you are GO for LOI.

Jerry Carr (CAPCOM)

Apollo 8, Houston. You are riding the best one we can find around.

Jerry Carr (CAPCOM)

You are riding the best bird we can find. Over.

Frank Borman (CDR)

Roger. It's a good one.

Bill Anders (LMP)

The cryo's have been stirred, Houston.

Jerry Carr (CAPCOM)

Apollo 8, Houston. We just saw an MC&W light.

Bill Anders (LMP)

We just tested the caution and warning.

Jerry Carr (CAPCOM)

Roger. Clint there is getting white.

Jerry Carr (CAPCOM)

Apollo 8, Houston. We're 42 minutes from LOS, and we caught another caution and warning light.

Frank Borman (CDR)

It was the high-gain antenna going out of limits.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Voice quality on the DSE dump is very good. The DSE is yours. Over.

Jerry Carr (CAPCOM)

Apollo 8, Houston. COMM check.

Jim Lovell (CMP)

Read you loud and clear, Houston.

Frank Borman (CDR)

Houston, Apollo 8. Over.

Frank Borman (CDR)

Roger. We are ready to activate the primary water boiler.

Frank Borman (CDR)

Okay. Steam pressure going to AUTO; H2 flow going to AUTO.

Jerry Carr (CAPCOM)

Apollo 8, Houston. We are on low bit rate. We won't see your steam pressure; your RAD OUT is 33. Over.

Frank Borman (CDR)

Roger. We're below the boiling limit, and steam pressure is steady at 0.15.

Jerry Carr (CAPCOM)

Apollo 8, this is Houston. We have got our lunar map up and ready to go.

Bill Anders (LMP)

Houston, Apollo 8. Over.

Bill Anders (LMP)

Roger. We're showing a fuel pressure of 167, in AUX of 163. Wondering, do you think there's a possibility of us having a transient caution warning trip on fuel AUX pressure at the beginning of the burn that would correct itself nominally as we had a chance to pressurize? Over.

Jerry Carr (CAPCOM)

Roger. Understand; will check. Stand by.

Jerry Carr (CAPCOM)

Apollo 8, this is Houston. We've been reading fuel 173, AUX 167, holding steady for a long period of time. We expect no caution and warning trip. Over.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Nine minutes 30 seconds from LOS.

Jerry Carr (CAPCOM)

Roger. In about 10 seconds, we'll have you 19 minutes from ignition. Five, four, three, two, one -

Jerry Carr (CAPCOM)

Apollo 8, Houston. Five minutes LOS, all systems GO. Over.

Frank Borman (CDR)

Thank you. Houston, Apollo 8.

Jerry Carr (CAPCOM)

Roger, Frank. The custard is in the oven at 350. Over.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Two minutes until LOS.

Jerry Carr (CAPCOM)

Apollo 8, Houston. One minute to LOS. All systems GO.

Frank Borman (CDR)

Roger. Going to COMMAND RESET, tape recorder FORWARD low bit rate.

Jerry Carr (CAPCOM)

Roger. Safe journey, guys.

Jim Lovell (CMP)

We'll see you on the other side.

Jerry Carr (CAPCOM)

Apollo 8, 10 seconds to go. You're GO all the way.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Over.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Over.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Over.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Over.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Over.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Over.

Jim Lovell (CMP)

Go ahead, Houston. This is Apollo 8. Burn complete. Our orbit 160.9 by 60.5; 169.1 by 60.5.

Jerry Carr (CAPCOM)

Apollo 8, this is Houston. Roger. 169.1 by 60.5. Good to hear your voice.

Jerry Carr (CAPCOM)

Apollo 8, this is Houston. Verify your evaporator water control in AUTOMATIC. Over.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Over.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Over.

Jerry Carr (CAPCOM)

Apollo 8, Apollo 8, this is Houston, Houston. Over.

Frank Borman (CDR)

Roger, Houston. We read you loud and clear. How do you read us?

Jerry Carr (CAPCOM)

Apollo 8, this is Houston. Reading you loud and clear now. And verify your evaporator water control panel switch to the AUTO position. Over.

Frank Borman (CDR)

Roger. I am sure it is in AUTO.

Jim Lovell (CMP)

Burn status report as follows: burn on time, burn time 4 minutes 6-1/2 seconds, VGX minus 1.4, attitude is nominal, no trim, VGY was zero, VGZ was plus 0.2, DELTA-VC was minus 20.2, orbit 169.1 by 60.5.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Roger. The burn on time, burn time of 4:06.5, VGX is minus 1.4.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Verify your EVAP water control on panel 382 is AUTO. Your EVAP OUT temperature is high. Over.

Bill Anders (LMP)

Houston, Apollo 8. Roger. Primary EVAP is AUTO, H2 flow AUTO. Do you recommend activating the secondary water boiler?

Jerry Carr (CAPCOM)

Apollo 8, this is Houston. Reverify manual valve on panel 382, evaporator water control AUTOMATIC. Over.

Jerry Carr (CAPCOM)

Apollo 8, this is Houston. Recommend you activate your secondary water evaporator.

Bill Anders (LMP)

Secondary EVAP coming on line.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Turn off your DSE, and we will go to high bit rate. Over.

Jerry Carr (CAPCOM)

Apollo 8, this is Houston. And I will continue my readback of the burn status report. Copied VGX zero, VGY zero, VGZ 1.2, DELTA-V Charlie minus 20.2. Over.

Bill Anders (LMP)

Stand by; he's getting the chart out again.

Jerry Carr (CAPCOM)

Roger. Understand; 0.2 on VGZ.

Bill Anders (LMP)

Houston, this is Apollo 8. We are on malfunction 1 of 6, going through step 1 to step 2. Over.

Jerry Carr (CAPCOM)

Apollo 8, Houston. Roger. Copy.

Bill Anders (LMP)

Correction. That is to step 4.

Jerry Carr (CAPCOM)

Roger. Copy; to step 4.

Bill Anders (LMP)

Looks like the boiler dried out somewhere along the line.

Frank Borman (CDR)

Houston, this is Apollo 8. I would like to confirm that burn status report. VGX was minus 1.4, VGY 0. VGZ 0.2, minus 0.2 that is. DELTA-VC was minus 20.2 -

Frank Borman (CDR)

— apogee 169.1, perigee 60.5.

Jerry Carr (CAPCOM)

Apollo 8, this is Houston. Roger. I will read back again. The burn was on time, 4 minutes and 6-1/2 seconds, VGX minus 1.4, trim nominal, VGY zero, VGZ minus 0.2, DELTA-V Charlie minus 20.2. Over.

Jerry Carr (CAPCOM)

Roger. And we copy your apogee and perigee.
