Spacelog Apollo 11

Columbia, Houston. You're about one by, I could just barely make you out. I can't understand.

Houston, Columbia. How now?

Houston, Columbia. Over.

Houston, Columbia. Over.

Houston, Columbia. Over.

Houston, this is Eagle. Over.

Hey, Eagle. Houston loud and clear. Columbia was very weak. We were unable to read him.

Roger. We saw you come up over the horizon and it looks like you had a laser operating. Could you confirm that?

Eagle, Houston. Stand by. We'll check it. And, Eagle, Houston. Can you give us a burn report?

Roger. Stand by.

Okay. The CSI burn was on scheduled time of 125 19 3470, 51.5 feet per second was our solution. After chasing residuals a little bit, we ended up with a minus 0.2, plus 0.7, and minus 0.1. And in the AGS, at that time, we had plus 0.4, plus 0.9, and plus 0.3.

Eagle—Eagle, Houston. We copy. Any plane change? Over.

No. There was no plane change on CSI, and CSM had a 2.3 foot per second burn. We had a 2.9, and we elected to postpone that. Over.

Roger. We copy, Eagle. Thank you.

Houston, how do you read Columbia now?

Eagle, how about asking them for some high gain angles for me, will you, please?

Roger, Houston, do you have some high gain angles for Columbia? Over.

Roger, Eagle. And, Columbia, stand by. We'll have them for you shortly.

Eagle, Houston. Could you verify you switched lithium hydroxide canisters? Over.

That's affirmative. We started getting an erratic indication on primary, so we switched to secondary, and it was again erratic and I thought it might have been a sensor. But it's settled down now, and we're on the secondary. Over.

Roger. We copy. Mighty fine.

Go ahead.

***

Eagle, Houston. At your convenience, we'd like to go ahead and try your lithium hydroxides on the primary and let us take a look at it down here.

Columbia, Houston. Over.

Go ahead, Houston. ***

Houston, Eagle. Columbia's been reading you loud and clear on his OMNI's, but he hasn't had any luck in transmitting to you.

Roger, Eagle. Mighty fine. We don't hear Columbia though.

Okay.

We're burning ours, Mike. Minus 1.8.

Eagle, Houston. …

Columbia, Houston. …

Columbia, Houston. Over.

Columbia, Houston. You can go ahead and go to REACQ in the high gain. We should get you then.

Do you have some angles for him, Houston?

Roger. Pitch minus 30, yaw 180, for Columbia.

Okay. And what was your CSI—CDH solution, Mike?

***

Roger. Copy. Thank you.

And, Houston, Eagle. Got an ECS light—a CO₂ light. Partial pressure's reading about one half millimeter.

Eagle and Columbia, Houston. Roger. We copy.

Houston, how do you read Columbia?

Columbia, Houston. Go.

Eagle, Houston. We're sure that's a sensor problem. You can leave it on PRIMARY.

Okay.
