Spacelog Apollo 11

Okay.

I'm pumping up cabin pressure.

That was a funny one. You know, I didn't feel it shock, and I thought things were pretty steady. I went to RETRACT there, and that's when all hell broke loose. Were you guys—did it appear to you to be—that you were jerking around quite a bit during the retrack cycle?

Yes. It seemed to happen at the time I put the plus X thrust to it, and apparently it wasn't centered, because somehow or other I accidentally got off in attitude and then the attitude hold system started firing.

Yes. I was sure busy there for a couple of seconds.

Are you hearing me all right? I got a horrible squeal.

Yes. I agree with that, but we hear you okay. Over.

Houston, Apollo 11. Over.

Apollo 11, Houston. Go.

Roger. I'm supposed to adjust the oxygen flow in this thing to six tenths of a pound per hour, but being as how this transducer is not working right, could you give me an updated number?

Affirmative. You want to go ahead and adjust your O₂ flow until it just goes off the peg, and then crank the direct O₂ valve back down about 5 degrees. Over.

Boy, you were really waiting for that one, weren't you? Okay, Ron. Thank you.

Houston, I did that, and I believe we are flowing oxygen, but the gage is just pegged FULL SCALE LOW.

Roger. That's fine. That's what we expect.

Okay.

Okay. I'm going to go ahead with the tunnel leak check.

Columbia, Houston. I have a new LM weight for you whenever you're ready to copy.

Not right now, Ron. Remind me of it later, would you please?

Roger. We'll stand by.

Houston, Apollo 11. I let P47 run longer than I should. I may have deteriorated our state vector slightly.

Roger, Apollo 11. That's okay. We'll see later.

Houston, Apollo 11. Go ahead with your DAP up, please.

Roger. Your LM weight, 5785. For an R1 we'd like to have 61102, R2 01111. Use BD roll. Over.

Roger. I'm configured now at … for BD roll, and I have thrusters C4 and B3 turned off, and I copy register 1 61102 01111 and LM weight 5785. Thank you.

Houston, Columbia has completed the leak check, and proceeding with opening the hatch dump valve.

Roger, Columbia. Understand you're doing the leak check. I missed anything after that.

I say the leak check is complete, and I'm proceeding with opening the hatch dump valve.

Eagle, Columbia.

Go ahead.

My hatch is removed. You can open yours, and I'll start passing stuff up to you.

Okay.

No. Stand by one, first.

Mike, you …

Yes, everything is going fine. Be with you in just a second.

Eagle, Houston. Over.

Go ahead, Houston, Eagle here.

Roger. Any time prior to jettison there, we'd like an AGS to PGNS align: 400 plus 30 000. Over.

Okay. Any particular attitude you would like the PGNS in when we do that?

No. We're not getting any. Could you give us some course align gimbal angles to move the PGNS to, and then we will align the AGS to the PGNS. Over.

Roger. Eagle. We concur. Stand by on the gimbal angles. And also, Eagle, while we've got the command module direct O₂ on there, there's a possibility that your cabin relief might relieve if we get up around cabin pressure of about 5.4 or 5.5.

Roger.

Eagle, Houston.

Roger. Go ahead.

Roger. All we are trying to do is get PGNS and AGS aligned together. Doesn't make any difference on the gimbal angle.

…

Okay. We are pretty close to 000. Is that all right?

Eagle, that's beautiful.

Now, you might want to take into account what will happen when the CSM maneuvers to jettison attitude.

Eagle, Houston. We don't care what—All we are trying to do is get a drift rate and see how long it takes them to drift apart on the thing after you jettison.

Okay. Will we be jettisoning at about this attitude? That's okay. I'll align the AGS with the PGNS. You can tell me a little later if you need some help.

Houston, Columbia. You want me to roll over and get high gain or anything like that?

Columbia, Houston. I can give you some REACQ angles for the high gain on the LM jettison attitude. Then you can go there whenever you want to. The angles are pitch minus 50, and yaw zero.

Okay.

Houston, Columbia. Say again the jettison roll, pitch, and yaw, please.

Columbia, Houston. Roll zero, pitch 025, and yaw zero. Over.

Roger. Understand roll zero, pitch 025, yaw zero.

That's affirmative.

… in progress. We've moving. Houston.

Houston, Eagle. Over.

Eagle, Houston. Go.

Roger. It doesn't appear as though the red hose is going to be much of a competitor to the leading vacuum cleaner brands. Over.

There's a little noise there, Buzz. Say again.

Eagle, Houston.

Roger. Go ahead.

Roger. Just a reminder to be sure to zero the AGS errors before you enable the AGS attitude hold there after you get in burn attitude.

Roger. You mean SEP attitude?

Houston, how do you read Columbia on high gain now?

Hey, Columbia. Houston. Mighty fine; loud and clear.

Same here, Ron. Thanks.

And Eagle, Houston. Your steerable antenna angles for jettison attitude are—Over.

Roger. Go ahead.

Roger. Pitch 165, yaw 68. Over.

Roger. Pitch 165, yaw 68.
