Spacelog Apollo 11

Apollo 11, Houston. Our procedures guys are saying that the reticle does not have to be parallel. Over.

Well, then we're not at the substellar point if we're not.

Houston, you copy that NOUN 49?

Roger. We see it, 11. Stand by.

Apollo 11, Houston. We would like you to accept this one and every mark thereafter. Over.

Okay.

Do you need me to wait in the NOUN 49 display for any length of time?

Negative.

Okay.

Okay, Charlie. I'll be glad to give you as many of these as you like.

Roger. We'd like six marks on star 45, Mike, and then we'll probably go back to star 2 again. Stand by. We'll have further word on that.

Okay.

They seem to be getting smaller, Charlie. Are you sure you wouldn't like some more?

Stand by, Mike.

It's no trouble.

Roger. Stand by. Out.

Apollo 11, Houston. We'd like you to do two more on star 45. Over.

Okay.

Okay, Charlie. There's your two more marks. Where do you want to go from here?

Stand by.

Hello, Apollo 11, Houston. We'd like you to go back to star number 2 with an attitude as follows: roll 1952, pitch 1239, yaw 3400. Mike, that'll give you a trunnion angle of about 31.4. Over.

Okay. I understand star number 2 and roll 195.2, itch 123.9, and yaw 340.0. Over.

That's affirmative.

Okay, Charlie. I'm there, and I've got a trunnion angle of 30.5 degrees. Again, misaligned considerably in roll and I do believe that's important to getting good marks.

Stand by.

See, if my reticle's not parallel, then I'm not marking normal to the horizon and I'm not marking at the substellar point. I'm marking off somewhere else.

Stand by one. Over.

Okay.

Apollo 11, Houston. The ground-computed values for your shaft and trunnion are just what you're getting on the DSKY there, Mike. The horizon looks cocked off to you—You look like you're off in roll because the angles that we gave you to maneuver to, to prevent LM reflection from fouling up your optics, we feel like a—You should go ahead and mark on the stars just as is. Over.

Okay.

I'll bet you a cup of coffee on it.

Copy.

VERB—NOUN 49 for you, Charlie.

Roger. Stand by.

Apollo 11, Houston. We'd like to accept this one and give us two more and that will be enough. Over.

Apollo 11, Houston. We see your termination on P23. Thank you very much. Mike, we'll have a—We're trying to work up a story here for you; we'll be with you momentarily on an explanation of what's happening. Over.

Okay, Charlie. It just appears to me that you have to have a reticle tangent to the horizon at the point at which you mark or else you're not at the substellar point; you're off laterally, and therefore you're measuring a larger trunnion angle than you should.

Seems so to me. Our procedures people are working on this, and we'll be back with you momentarily. Over.

Thank you, sir.

Hello, Apollo 11. Houston. We'd like you to go P00 in ACCEPT. We'll have a PTC REFSMMAT for you momentarily. Over.

Hello, Apollo 11. Houston. We're through with the load. You can go back to BLOCK.

Hello, Apollo 11. Houston. We'd like you to do a P52, option 1 preferred, and establish PTC as listed in the flight plan at 12 hours. We'd like you to commence that right now, Mike. And we have some stars recommended for you. For stars 26, 30, and 24, when you get to attitude 000. Over.

Okay, Charlie. He's off the wick right now. Understand you're ready for us to do a P52, option 1?

11, it's a P52, option 1 preferred. Over.

Roger. And, let's see, that is Spica, Menkent, and what else?
