Spacelog Apollo 8

Houston, this is Apollo 8.

Houston, Apollo 8.

Apollo 8, go ahead.

Roger. We tried to get this realignment. We need—Do you have a maneuver to get us some gimbal angles so we don't get gimbal lock when we get the preferred alignment?

Stand by on that.

Thank you.

Houston, on our present position, we'll go into gimbal lock. I figure to try and get the preferred angle.

Say again, Apollo 8.

In running through PROGRAM 52, we got a PROGRAM ALARM 401 which would indicate that if we continued, we'd drive it into gimbal lock.

Roger. I understand.

Apollo 8, Houston. This should be an OPTION 1 like OPTION 3.

Houston, we're doing an OPTION 1 like OPTION 3. We keep getting a 401 ALARM, which says desired RCTU yields gimbal lock.

Apollo 8, Houston. It appears that you have maneuvered around the gimbal locks system.

Roger. Roger.

Okay. Sorry we were late on that answer.

Thank you.

Houston, Apollo 8.

Go ahead.

Well, we stopped and went through coarse align of P52 and then we got fine align, and pick-a-pair, pick Capella, but she drove and didn't get to any place. I didn't pick Capella, and I can't recognize any out there right now. Can I re-cycle here and go back and pick a pair?

Houston, Apollo 8.

Go ahead, Apollo 8.

My plan is to go back into re-enter PROGRAM 52—well, it did not drive to Capella, and I can't recognize it in the scanning telescope. My plan is to go back into recall P52.

Okay. Stand by one.

Okay.

Houston, Apollo 8. We came up with an unacceptable difference in our stars; we're going to have to recycle.

Roger.

If we don't get this midcourse in, what will that do to our pericynthian?

Stand by. We'll -

Apollo 8, Houston. In the event that we don't get this midcourse in, we'll still go for an LOI, and it's been suggested you might try Mirfak which is OCTO 10.

That's the one we're trying now.

Houston, Apollo 8.

Go ahead.

We are all set up and counting down at 8 minutes.

Roger.

Apollo 8, our data is down right now; appreciate making sure you have the tape recorder on.

Roger. I am going to go—I'll have to go COMMAND RESET. You've got control.

Houston, Apollo 8.

Go ahead.

Roger. You have some pitch and yaw angles for our PTC extra burn.

Okay, Apollo 8. That's pitch 348, yaw 315.

Pitch 348, yaw 315.

That's affirmative. And would you give us another hack on your countdown time?
