Spacelog Apollo 11

Hey, Houston, Apollo 11. That Saturn gave us a magnificent ride.

Roger, 11. We'll pass that on. And, it certainly looks like you are well on your way now.

We have no complaints with any of the three stages on that ride. It was beautiful.

Roger. We copy. No transients at staging of any significance. Over.

That's right. It was all—all a good ride.

Houston. Roger. Out.

Apollo 11, this is Houston. For your information, we expect the maneuver to separation attitude to begin at 3 plus 05 plus 03, and to be completed at plus 09 plus 20. Separation at 3 plus 15 plus 00.

Roger. Time to begin maneuver is 3 05 03, complete 3 09 20. Separation 3 plus 15 00.

Roger. That separation should be 3 plus 15 03. My error in reading up.

Roger.

Apollo 11, this is Houston. All the booster functions are proceeding normally. The sequencing is in good shape, and it doesn't look like they are having any problems at all. Over.

Apollo 11, Apollo 11, this is Houston. Over.

Apollo 11, Apollo 11, this is Houston. Over.

Hello, Houston. Hello, Houston. This is Apollo 11. I'm reading you loud and clear. Go ahead. Over.

Roger, 11. This is Houston. We had to shift stations. We weren't reading you through Goldstone. We show PYRO bus A armed and PYRO bus B not armed at the present time. Over.

That's affirmative, Houston. That's affirmative.

Apollo 11, this is Houston. You're GO for separation. Our systems recommendation is arm both PYRO buses. Over.

Okay. PYRO B coming armed. My intent is to use bottle primary 1, as per the checklist; therefore, I just turned A on.

Houston, we're about to SEP.

This is Houston. We copy.

Roger. We are docked. We do have acquisition with the high gain at this time, I think.

Understand you are using the high gain. Over.

That's affirmative.

That's affirmative.

Houston, CDR. How do you read …?

11, CDR, loud and clear, Neil.

11, this is Houston. Over.

Houston, Apollo 11. Go ahead.

Roger. When you commented on that quad Bravo problem at separation, you were a little weak. Could you go through what you did after you noticed the talkbacks barber pole again, please?

We copied the—the primary and secondary propellant talkbacks on SM RCS quad Bravo 1 to barber pole on separation.

Roger. Roger. That is affirmative, and we moved that switch to the OPEN position, and they went back to gray. Over.

Apollo 11, this is Houston. Over.

Roger, Houston. Apollo 11. Go ahead.

Roger. Could you give us comments on how the transposition and docking went? Over.

I thought it went pretty well, Houston, although I expect I used more gas than I've been using in the simulator. The turnaround maneuver—I went PITCH ACCEL COMMAND and started to pitch up, and then when I put MANUAL ATTITUDE PITCH back to RATE COMMAND for some reason it—it stopped its pitch rate, and I had to go back to ACCEL COMMAND and hit what I thought was an extra PROCEED on the DSKY. During the course of that, we drifted slightly further away from the S-IVB than I expected. I expected to be out about 66 feet. My guess would be I was around 100 or so; and therefore, I expect I used a bit more coming back in. But, except for using a little more gas—And I'd be interested in your numbers on that—everything went nominally.

Houston, Apollo 11. Over.

Go ahead, 11.

Roger. We're working on the pressurization of the LM now, and working off the decal with CSM-LM pressure equalization. And we're down to step 13, where we're waiting for the cabin pressure to be 5, or it should be roughly 5, before we turn the REPRESS package O₂ valve to FILL. Instead of 5, we're running about 4.4. Over.

Roger. Stand by a second.

And Houston, Apollo 11. We did put the REPRESS package O₂ valve to FILL momentarily there at step 13, and we have filled the bottles back up partially. What's the pressure reading in there, Neil?

We have about 450 psi now in the three 1-pound bottles.

Roger. Stand by a second, please.

Houston, Apollo 11. We think these readings are within normal tolerances. We just wanted to get your concurrence before we press down any further with these decals.

Okay, Captain.

Houston, Apollo 11. How do you read?

Apollo 11, this is Houston. Go ahead.

Roger. LM looks to be in pretty fine shape from about all we can see from here.

Okay. In reference to your question on this step 13 on the decal, I understand that you have used up the contents of the REPRESS O₂ package and at that time, instead of being up to 5 psi, you were reading 4.4. Is that correct?

Okay. 4.4. Yes sir.

Okay. And you want to know if you can go ahead and use additional oxygen to bring the command module up to 5.0 and continue the equalization? Over.

Yes. We think it's within normal tolerances, Bruce. We just wanted to get your concurrence before we press on with this procedure.

Roger, Apollo 11. Go ahead.

Okay. We're pressing on with the procedure.

And 11, Houston. We have a request for you. On the service module secondary propellant fuel pressurization valve: As a precautionary measure, we'd like you to momentarily cycle the four switches to the CLOSE position and then release. As you know, we have no TM or talkback on these valve positions, and it's conceivable that one of them might also have been moved into a different position by the shock of separation. Over.

Okay. Good idea. That's being done.

Houston. Roger. Out.

Apollo 11, Houston. We're doing a nonpropulsive vent on the booster at the present time. You may see some sort of a cloud coming out of it. When you're ready, I have your evasive maneuver PAD.

Roger, And it's coming out.

Roger. Out,

It's a haze. It's going by toward our minus-X direction, and several small particles are moving along with it. The actual velocity is fairly high—at least it appears to be high. And we've got an O₂ high—it's a little high right now.

Houston. Roger. Out.

And, Houston, you, might be interested that out my left-hand window right now, I can observe the entire continent of North America, Alaska, and over the Pole, down to the Yucatan Peninsula, Cuba, northern part of South America, and then I run out of window.

Houston, Apollo 11. All 12 latches are locked.

Roger. 11, this is Houston. Understand 12 latches locked.

11, Houston. Whenever you're possessed of a free moment there, we've got this evasive maneuver PAD.

Okay.
