Spacelog Apollo 11

No. We haven't changed any canisters this morning.

Okay. Then you can plan on accomplishing that after P23 is over and you've got the LEB clear.

All right.

Houston, Apollo 11. We're in process of maneuvering to P23 in desired attitude. It likes roll 8.37, pitch 61.33, and yaw 339.87. Over.

Roger. We copy. And that is for star 01?

Star 01, right near the horizon. Code 110.

Houston, Apollo 11. On this star, the AUTO maneuver works just fine. I am right at the substellar point. Everything looks beautiful except there is no star in sight. It is just not visible.

Roger. Is this for star 01?

That's correct.

You are not getting any reflections or anything like that that would obscure your vision, are you?

Well, of course, the Earth is pretty bright, and the black sky, instead of being black, has sort of a rosy glow to it. The star, unless it is a very bright one, is probably lost somewhere in that glow, but it is just not visible. I maneuvered the reticle considerably above the horizon to make sure that the star is not lost in the brightness below the horizon. However, even when I get the reticle considerably above the horizon so the star should be seen against the black background, it still is not visible.

Roger. We copy. Standby a minute, please.

11, this is Houston. Can you read us the shaft and trunnion angle off the counters?

Yes. I will be glad to. Shaft 331.2 and trunnion 35.85.

It's really a fantastic sight through that sextant. A minute ago, during that AUTO maneuver, the reticle swept across the Mediterranean. You could see all of North Africa, absolutely clear; all of Portugal, Spain, southern France; all of Italy, absolutely clear. Just a beautiful sight.

Roger. We all envy you the view up there.

But still no star.

11, this is Houston. Over.

Roger. Go ahead, Bruce.

On our ground computers we confirm the shaft and trunnion angle that you have as being pointed at the star. However, it looks as though that shaft and trunnion angle is also pointing into the structure of the LM, so that while you will be getting the Earth's horizon, the star … is obscured by the LM. We recommend an AUTO maneuver to the attitudes pen-and-inked into the flight plan. Roll 1772, pitch 2982 and yaw 330.0. Over.

11, this is Houston. While you're maneuvering, could we get a /CM DELTA-P reading from you? Over.

Roger. Just a tad under 1, Bruce, 0.95.

Apollo 11, Houston.

Go ahead.

Is the Commander aboard?

This is the Commander.

I was a little worried. This is the backup Commander still standing by. You haven't given me the word yet. Are you GO?

You've lost your chance to take this one, Jim.

Okay. I concede.

Houston, Apollo 11.

Go ahead, 11.

Okay. Our maneuver is complete, and at this attitude the M-line is exactly 90 degrees out of phase. It is exactly pointed along the vector toward the center of the Earth instead of being parallel to the right.

Roger.

I'm going to hold right here for your next suggestion.

Okay, Houston. It appears to be okay now; We've changed our attitude slightly, and I have a star and I'm maneuvering to get the M-line parallel.

This is Houston. Roger. We copy.

Houston, Apollo 11. Are you copying these NOUN 49's that have been going through?

Yes. We surely are. Let's see: plus 0.1 and a plus 0.2 on nautical miles and feet per second. Over.

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 …

Roger.

Maybe you can make it just the change in roll.

Roger.

Apollo 11, this is Houston. Over.

Go ahead.

Roger. On your attitude for the burn: we'd like you to use roll 096, pitch 356, yaw 018. That will give you a sextant star of 01, shaft 253.8, trunnion 24.2. Over.

… 356 …

11, this is Houston. We are having difficulty reading you through the noise. Could you read back again, please? Over.

Roger, Houston. Apollo 11. Do you copy?

Roger. Very weakly in the noise, but I think I can copy. Go ahead.

Okay. Roll 096 356 018 … star 01 …

Roger. I got all of that except trunnion. It's trunnion 242. Over.

Houston, Apollo 11. How do you read me now on OMNI A?

Roger. Loud and clear, 11.

Okay. We'll stay on OMNI A for a while, then.

Okay. I got all your readback except the value for trunnion. If it's 242, confirm, please.

Roger. 242.
