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)
-
I'm getting the COAS right on it now so it will be accurate.

-
Okay. With the COAS right on the S-IVB, the roll reads 105, the pitch is 275, and the yaw is about 325.
- Frank Borman (CDR)
-
Roger. That should be 115 for the roll.

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.
- Frank Borman (CDR)
-
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.
- Mike Collins (CAPCOM)
-
Roger.
- Mike Collins (CAPCOM)
-
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.
