Houston, we are going to have to hold up on the cislunar navigation until after this next little maneuver.
- Mike Collins (CAPCOM)
-
Can you give us an updated readout of your gimbal angles. When your plus X-axis is pointed toward the booster, please?
- Frank Borman (CDR)
-
Okay. With the COAS right on the S-IVB, the roll reads 105, the pitch is 275, and the yaw is about 325.
- Bill Anders (LMP)
-
Roger. If it will help you any, Mike, the earth is plus Y about 45 degrees in a minus X. I can see it out my side window, and it's a beautiful view with numerous cloud vortex.
- Mike Collins (CAPCOM)
-
Roger, Bill. Thank you. Understand; plus X 45 degrees halfway between plus Y and plus Z and slightly minus X.
- Mike Collins (CAPCOM)
-
Roger. Understand. Frank, what we want on this burn is 8 feet per second now, 8 feet per second. We want it radially upward, and we want you to use whatever thrusters are required to burn radially upward at 8 feet per second.
- Mike Collins (CAPCOM)
-
Because of the separation distance we would like to achieve between now and the time of S-IVB blowdown.

Mike, do you want me to go ahead and try to do this, or are you going to give me some gimbal angles?
- Mike Collins (CAPCOM)
-
Apollo 8, Houston. Go ahead and do it without gimbal angles, if you can do that. Over.
- Frank Borman (CDR)
-
Okay. I don't understand why you want so many feet per second on it, but I think I can—with just a little maneuvering, I can get away from it a lot simpler than that.
- Mike Collins (CAPCOM)
-
Well, we would like the radial upward for trajectory reasons, and the magnitude we'd like because of the separation distance which we're predicting you will have at S-IVB blowdown.
- Mike Collins (CAPCOM)
-
Roger. About 12 minutes before your big blowdown, there is a small continuous vent which opens at a GET of 04:55:55. You may notice that on the booster, 12- or 15-pound thrust.

-
Roger.

Apollo 8, Houston. Are you going to use P47 to monitor the burn?
- Jim Lovell (CMP)
-
Yes, Jim, that's Roger. We are putting it in right now.
- Mike Collins (CAPCOM)
-
Thank you.
- Frank Borman (CDR)
-
Houston, we made the burn at 7.7 plus X plus 00001 Y; and Z's are all zeros. Gimbal angles, roll 180, pitch 310, and yaw 020.
- Mike Collins (CAPCOM)
-
That's affirmative. I say again, we copied plus X 7.7, one-tenth in Y, no Z; roll, pitch, and yaw, 180, 310, and 020.
- Frank Borman (CDR)
-
Okay. Do you want us to transfer that to the CS—to the LM state vector or just leave it alone? You —
- Mike Collins (CAPCOM)
-
Affirmative, Frank. We would like you to transfer from the CSM to the LM state vector.
- Mike Collins (CAPCOM)
-
How is that booster looking now? Is it drifting away rapidly, or how does it look?
- Mike Collins (CAPCOM)
-
Roger. Understand; 90 degrees from its X-axis and about 1000 feet and separating.
- Frank Borman (CDR)
-
Houston, this is Apollo 8. I think we've got clearance now; we got a little behind on our P23's, but I suggest we go ahead and start those now.
- Mike Collins (CAPCOM)
-
Roger, Bill. Thank you, and at your convenience, could you give us the PRD reading? And as far as the P23 goes, that's just fine to get started with it. It looks like your first star, which is number 14, should be good until about 05:15 GET. Over.
- Mike Collins (CAPCOM)
-
Got that. Copy left to right: 0, 0.64, and 0.02 at 4 hours and 4 minutes. Thank you.
- Bill Anders (LMP)
-
Roger. At 04:53, it was 0.01, 0.64, 0.03, and negligible on the survey meter.

I have a beautiful view of the S-IVB and the earth here on one. I'll try and get a picture for you.
- Mike Collins (CAPCOM)

Apollo 8, Houston. We've got you about a minute away from the continuous vent open and 14 minutes away from the big dump, and we would like an estimate on your distance now if you can give it.
- Jim Lovell (CMP)
-
Boy, it's really hard to describe what this earth looks like. I'm looking out my center window, which is a round window, and the window is bigger than the earth is right now. I can clearly see the terminator. I can see most of South America, all the way up to Central America, Yucatan, and the peninsula of Florida. There is a big swirling motion just off the east coast, and then going on over toward the east, I can still see West Africa, which has a few clouds right now. We can see all the way down to Cape Horn in South America.
- Frank Borman (CDR)
-
Yes. Tell the people in Tierra Del Fuego to put on their raincoats; looks like a storm is out there.
