Spacelog Apollo 11

That was Neil. How are you reading Mike?

Loud and clear now, Mike, and we understand that you are docked.

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.

Apollo 11, this is Houston. Do you read? Over.

All of a sudden there, we heard a little click, and the signal strength began to start dropping off. Your transmissions were cut off very abruptly. How do you read now?

Roger. Loud and clear. We had a handover to Madrid about the time I was—I guess halfway through the PAD. If you could give me the last value you read, I'll pick up there. Over.

Okay. Start with DELTA-VZ. Over.

Roger. DELTA-VZ is plus 00190, roll your option, pitch 213 357, and NOUN 44 is NA. DELTA-VT 00197 003 00152. The rest of the PAD is NA, and no ullage. LM weight 33,290. Read back. Over.

Roger, Houston. Evasive maneuver SPS G&N: 63481, plus 095, minus 020 004 40 0100, plus 00051, plus all zeros, plus 00190, roll crew option, 213 357, NA, 00197 003 00152, no ullage, LM weight 33,290. Over.

Houston, Apollo 11.

Go ahead, 11.

We'd like to arm our logic switches.

Go ahead with the logic.

Okay. Mark logic 1 and 2 armed.

Houston, we're ready for LM ejection.

Roger. You're GO for LM ejection.

Thank you.

Houston, we are SEP. We have a CRYO PRESS light.

Roger. Copy. CRYO PRESS light.

Roger, 11. We recommend you turn the O₂ fans on manually and ensure that the O₂ heaters are in the AUTOMATIC position.

Roger. O₂ heaters are ON, and we're going to cycle the O₂ fans now.

Apollo 11, this ls Houston. Over.

Houston, Apollo 11.

Roger. In reference to your question on RCS usage: it looks like you are about 18, maybe 20 pounds below nominal at the present time. No problem at all. Over.

Right.

I wanted to be 18 or 20 pounds above nominal, babe.

Houston, Apollo 11. Could you confirm that pitch gimbal motor number 1 turned off? We just shut all four off, and we got a questionable indication on the ECS on pitch 1.

Roger. Stand by a second.

Houston, did you copy our residuals?

Apollo 11, this is Houston. Stand by, please.

Go ahead, Houston. Did you copy our residuals?

Roger. We got 00 and 0.2, it looks like.

We had 0.1 while ago. It's—just went to 0.2.

Okay.

That EMS DELTA-V counter is minus 4.0.

Minus 4.0. Roger.

And how about pitch gimbal 1? Can you confirm that OFF?

Can you stand by just a second on that? At the present time we cannot confirm it OFF. We saw a current drop indicating that several gimbal motors had gone off. We'll be back with you in just a second on it. Over.

Okay, If necessary, we can recycle it.

Apollo 11, this is Houston. If you'll go ahead and cycle pitch gimbal motor number 1 on and then off and give us a Mark, and we'll tell you what we see. Over.

Okay, fine. It's coming back on. Ready.

MARK.

And it's going back off. Ready.

MARK.
