Spacelog Apollo 11

And that time we got an onboard indication, Houston. Thank you a lot.

Roger. We confirm that it is OFF.

Yes. We do likewise.

Houston, Apollo 11. We're starting our maneuver to observe the S-IVB slingshot.

Roger, 11. We've got an updated attitude for you on the slingshot observation.

Okay. Say the angles please.

Roger. Roll 002.5, pitch 289.3, yaw 357.5, and there's also an update—minor correction to your attitude for the P52. Over.

Roger. I have roll 002.5, pitch 289.3, and yaw 357.5. Over.

Roger. And for your P52 and optics calibration, it'll be roll 346.5, pitch 345.0, and yaw 007.8. Over.

Roger. 346.5, 345.0, and 007.8. Thank you.

Apollo 11, this is Houston. Over.

Roger. Go ahead, Houston. Apollo 11.

Roger. We're going to go ahead and enable the S-IVB for the slingshot maneuver. The LOX dump will start about 12 minutes from now. Over.

Okay, LOX dump about—I guess that'll make it about 01, huh?

Right. I'll try to give you a little closer update as we approach it.

Alright.

And, 11, for you information, the magnitude of midcourse correction number 1, if we burn, looks like about 17 feet per second. We're presently considering not burning it. This would make midcourse correction 2 tomorrow about 21.3. Over.

That sounds good to us.

Roger. You're looking good down here.

Well, we didn't have much time, Houston, to talk to you about our views out the window when we were preparing for LM ejection; but up to that time, we had the entire northern part of the lighted hemisphere visible including North America, North Atlantic, and Europe and Northern Africa. We could see that the weather was good all—just about everywhere. There was one cyclonic depression in Northern Canada, in the Athabaska—probably east of Athabaska area. Greenland was clear, and it appeared to be we were seeing just the icecap in Greenland. All North Atlantic was pretty good; and Europe and Northern Africa seemed to be clear. Most of the United States was clear. There was a low—looked like a front stretching from the center of the country up across north of the Great Lakes and into Newfoundland.

Roger. We copy.

I didn't know what I was looking at, but I sure did like it.

Okay. I guess the view must be pretty good from up there. We show you just roughly somewhere around 19,000 miles out now.

I didn't have much outside my window.

Houston, Apollo 11. We've completed our maneuver to, observe the slingshot attitude, but we don't see anything—no Earth and no S-IVB.

Roger. Stand by. In GET I have a LOX dump start time for you. It's supposed to start at 5 plus 03 plus 07, and stop at 5 plus 04 plus 55. Ullage burn starts at 5 plus 37 plus 47, stops at 5 plus 42 plus 27. Over.

11, Houston.

Go ahead, Houston.

Roger. We now recommend the following attitude: roll 307.0, pitch 354.0, yaw 019.5, and the LOX dump has already been enabled, so we can't hold it off any longer.

That's okay. Go ahead. We'll maneuver around to 307, 354, and 19 and a half. Thank you sir.

Roger.

11, Houston. It doesn't look to us like you'll be able to make it around to this observation attitude in 2 minutes. We recommend that you save the fuel. Over.

Okay, Houston. You got to us just a little late. Our maneuver's already begun, so it's going to cost us about the same amount of fuel to stop it, no matter where we stop it, and we may as well keep going.

Roger. Go ahead.

11, Houston. LOX dump initiated.

11, Houston. LOX dump has been terminated. Over.

Roger.

Roger. We still don't have …

Apollo 11, this is Houston. Over.

Go ahead.

Roger. If you'll give us ACCEPT and stay in P00, we'll set your trunnion bias to zero. And, I have a plan for balancing your oxygen CRYO's. Over.

You got it.

Roger.

Houston, Apollo 11. We've got the—what appears to be the S-IVB in sight—at—oh, I'd estimate a couple of miles away. It's at our number 5 window and the dump appears to be coming out of two radially opposite directions from the S-IVB.

Roger. They're continuing with the nonpropulsion vent from the liquid oxygen tank. It would be radially opposite, then. And boosters tell me it's the continuous vent system. They're also dumping a small amount of fuel at this time. We've got about 23-1/2 minutes or so until the APS burn. Over.

Roger. We have that except the last one was H₂ fans to OFF. Is that affirmative?

We have—The configuration we have now is—Hydrogen heaters: we got 1 AUTO, 2 OFF. Oxygen heaters: 1 OFF, 2 AUTO. And we have all the fans OFF.

This is Houston. Roger. We concur. Out.

11, this is Houston. We've completed the trunnion zero bias setting. You can retrieve the computer and go to BLOCK.

11, this is Houston. With this maneuvering to observe the slingshot, I guess we missed copying your LM/CM DELTA-P reading. Over.

Stand by. We'll give you a …

Roger.

Right now, reading 0.2, Bruce.

Roger. 0.2.

Okay, Mike. And could you verify that your waste compartment valve is in VENT, there?

Roger. Waste compartment valve has been in VENT for—oh, I guess, 45 minutes or so.

Roger. We copy.

If we're late in answering you, it's because we're munching sandwiches.

Roger. I wish I could do the same here.

No. Don't leave the console!

Don't worry. I won't.

FLIGHT doesn't like it.

How is FLIGHT today?

Houston, 11.

Go ahead, 11.

Down in the control center you might want to join us in wishing Dr. George Mueller a happy birthday.

Roger. We are standing by for your birthday greetings.

I think today is also the birthday of California, and I believe they are 200 years old, and we send them a happy birthday. And I think it's Dr. Mueller's birthday, also, and I don't think he is that old.

Roger. We copy. I'm looking back in the viewing room right now. I don't see him back there.

He may not be back from the Cape yet.

Roger. I believe Dr. Mueller is on his way back from the Cape. We will relay his greetings for you.

11, this is Houston. Over.

Go ahead, Houston.

Roger. At your convenience, we would like to get a waste-water dump to 5 percent remaining. After completion of this one, the next wastewater dump will be at about GET equal to 25 hours. Over.

Coming on right now.

Houston, Apollo 11. Did you copy our torquing angles?

Roger. Leave them on there probably a second, please.

Will do.

11, this is Houston. We copy the angles, but stand by before you go ahead and use them. Over.

Standing by.

11, Houston. We request that you read P52, and if the angles come out the same magnitude, go ahead and incorporate them. Over.

Okay. We'll do that.

They look a little large right now.

Yes. Roll—roll locks a little large, especially, there.

Roger.

We're showing a waste-water quantity of about 13 percent on TM now, 11. Over.

Roger. It's off, now

Roger. We copy.
