Spacelog Apollo 11

Apollo 11, this is Houston. Over.

Go ahead.

Roger. We show you as a little less than an hour to the midcourse correction number 2 burn. We recommend that you terminate the P23 activities here and press on with the waste-water dump, which we need from you, and get it ready for the burn. Over.

Okay.

And I have your midcourse correction number 2 PAD when you're ready to copy.

Stand by.

Roger, Houston. Apollo 11, ready to copy MCC 2.

Apollo 11, this is Houston. Midcourse correction number 2. SPS/G&N 63059, plus 097, minus 020, GET ignition 02644 5792, plus 00118, minus 00003, plus 00177, roll 277 355 015, NOUN 44 BLOCK is NA, DELTA-VT 00213 003 00168, sextant star 30 2082 370. The rest of the PAD is NA. GDC align: Vega and Deneb. Roll align 007 144 068. No ullage. LM weight: 33302. For your information, your heads will be pointed roughly towards the Earth on this burn. Read back. Over.

Roger. Midcourse correction number 2. SPS/G&N: 63059, plus 097, minus 020 02644 5792, plus 00118, minus 00003, plus 00177 277—Are you still copying?

Roger. Still copying. Go ahead. Apollo 11, this is Houston. I copied your transmission about roll 277, and go ahead from roll 277. Over.

Roger. 355 015, NA, 00213 003 00168 30 2082 370. Vega and Deneb 007 144 068. No ullage. LM weight: 33302. Heads towards the Earth. Over.

11, this is Houston. Readback correct. Out.

Apollo 11, Houston. Over.

Go ahead, Houston. Apollo 11.

Roger. We'd like you to terminate battery A at GET 26 hours and reinitiate battery A charge after midcourse correction 2. Over.

Apollo 11. Roger.

11, this is Houston. Over.

Go ahead.

Roger. If you can give us ACCEPT, we'll send you up a state vector and a target load for the maneuver.

Okay. Give us 1 minute to check the P23 damage.

Sure thing.

Houston, Apollo 11. The DSKY's yours.

11, this is Houston. We've completed the uplink. The computer's yours.

Houston, Apollo 11.

Apollo 11, this is Houston. Over.

Roger. Wonder if you have a star that might be a little closer to the direction we're burning than the one you gave us.

Roger. We're going to rework the attitude in the sextant star for you in order to improve the high-gain antenna coverage, and we'll have that for you in a few seconds.

Fine. We're already maneuvering …

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.
