Spacelog Apollo 11

Houston, Apollo 11. Could you give us a couple of high-gain antenna angles, please?

Roger. Stand by, 11.

Roger, 11. Pitch minus 35, yaw 0. Over.

Thank you.

We got them.

Okay.

Houston, Apollo 11. How do you read high gain?

Read you loud and clear on high gain down here, and everything's looking good from our standpoint for your burn. Over.

Houston, burn completed. You copying our residuals?

That's affirmative.

And, Houston, looked like we saw about 87 or 88 psi on chamber pressure that time. I'd like you to look at that on the ground.

Roger, 11. We'll take a look at that and get back in a few minutes.

11, Houston. On our real-time telemetry we saw 95 to 97 psi on chamber pressure. We'll—We will look at the recordings down here, thought, and get back with you again. Over.

Okay. Thank you.

And we've copied your residuals, 11.

11, Houston. Could we get your DELTA-V counter reading, please, from this burn?

That's minus 3.8.

Minus 2.8?

3.8.

Roger. Copy minus 3.8.

Houston, is there anything else you need on the burn status report?

This is Houston. Negative, 11.

Apollo 11, this is Houston. Over.

Roger. Apollo 11.

Roger. I just wanted to remind you that we haven't noticed on the TM the VERB 66 after the burn. And for your information, we played the recorded TV back last night, I believe, after you all turned in for your rest period, and the pictures came out quite well. Over.

Did you get any usable pictures out of MILA on that first pass?

Not that we've seen. We had word on the voice loop that MILA reported that they had gotten a minute's worth of TV signal, and Goldstone reported that they had gotten about a minute's worth of modulation but that they weren't able to get anything off of it.

Okay. Thanks.

Okay. We have another input here, 11, that the MILA data was recognizable as a picture, but we don't have any evaluation as to the quality of the picture. Over.

Okay.

And for our information, we've been watching a PCO₂ again. Did you change a lithium hydroxide canister this morning? Over.

Yes. We did, and we've been seeing 1.7 percent in the spacecraft ever since.

Roger. That agrees with our data.

1.7 millimeters.

Roger. We copy.

Houston, Apollo 11. We're starting our maneuver to PTC attitude.

11, this is Houston. Over.

Go ahead.

Roger. From a propellant-balancing standpoint, we recommend that you use quads Alfa and Bravo to start the PTC maneuvers. Over.

Roger. Understand Alfa and Bravo.

11, this is Houston. Over.

Go ahead, Houston.

Roger. For CRYO-balancing purposes, we'd like you to turn the heater and oxygen tank number 1 off at this time. Over.

Okay. Stand by.

Everything else in the CRYO system remains the same.
