Spacelog Apollo 11

Houston, Apollo 11.

Go ahead, 11.

Apollo 11, Houston. We'd like for you to go ahead and put your S band antenna OMNI to OMNI and OMNI B. Over.

Apollo 11, Houston. How do you read me through Honeysuckle now? Over.

You're loud and clear. Over.

Very good. Reading you better now. And did you copy we'd appreciate going S band OMNI and OMNI B at this time? Over.

That's the configuration we're in.

Okay. Thank you.

I'll say you “Purple” people keep funny hours.

Good afternoon, Houston. Apollo 11. Over.

Good morning, 11. This is Houston. Over.

Okay. Crew status report: 88 and 8.5.

Roger. 88 and 8.5. When you're ready, we've got a small flight plan update for you.

Houston, we're ready to copy.

Roger. At about 148 hours, if you've not already done so, a CO₂ filter change, and the H₂ purge line heater on 20 minutes before the O₂ and H₂ purge. At 148 hours, we'd like you to initiate a charge on battery Alfa instead of at 151 hours, and leave the charge on until we notify you further. At 150 hours GET, waste water dump to 10 percent. We do plan to burn midcourse correction 5. It will be an RCS burn about 5 feet per second at about the nominal time in the flight plan. Over.

Roger. Understand. We'll be accomplishing the filter change shortly, the purge line heater is on ***, O₂ and H₂ purge shortly, and at 148 will initiate a charge on battery A until you notify us further. At 150 hours, waste water dump to 10 percent. And we're looking forward to midcourse correction 5 at about 5 feet per second at the nominal time. Over.

Roger. I've got your consumables update, if you're ready to copy.

Copy.

Okay. At GET of 147 plus 00, RCS total minus 2.0 percent, which is about minus 14 pounds. Alfa minus 12.0, Bravo plus 10.0, minus 3.0, minus 2.0. Hydrogen total minus 1.5 pounds, O₂ total plus 20 pounds. Over.

Roger. I copy, and our onboard readouts: Alfa, *** 2 percent, Bravo 54 percent, Cocoa's 64 percent, Delta 61 percent. Over.

Roger, 11. Would you read that quad Alfa again, please, Buzz. You're cutting out. It may be—are you operating on VOX? Over.

Negative. Alfa is 53 percent. Over.

Roger. We copy.

Apollo 11, this is Houston. Over.

Go ahead.

Roger. Would you ask Buzz to check his biomedical TM sensors for a loose or dried out sensor? We're getting an erratic electrocardiogram reading. That would be one of the three sternal leads. Over.

Okay.

…

Apollo 11, this is Houston. Say again your last, please.

Disregard.

Apollo 11, this is Houston. Stand by for a Mark leaving the lunar sphere of influence.

MARK.

You're leaving the lunar sphere of influence. Over.

Roger. Is Bill Shaffer down there?

Negative. But we've got a highly qualified team on in his stead.

Roger. I wanted to hear him explain it again to the press conference.

Okay.

That's old Apollo 8 junk, but tell him the spacecraft gave a little jump as it went through the …

Okay. I'll pass it on to him. Thanks a lot, and Dave Reed is sort of burying his head in his arms right now.

Roger. Out.

Those guys down there in the press room did a pretty good job this morning.

Yes, they have.

We don't want them to give up yet, though.

No. They'll hang in there for about another 47 hours or so.

Roger. We're all listening. Go ahead.

Look up the Dow Jones Industrials for us.

Apollo 11, this is Houston. We see you in P00. When you can give us ACCEPT, we have a state vector and target load uplink ready for you.

Roger, Houston. I'm going ahead and start the computer.

Apollo 11, we've completed the uplink. The computer's yours.

Apollo 11, this is Houston. Over.

Go ahead.

Roger. With respect to the Dow Jones industrials, since closing on Tuesday afternoon the 15th up to about 1:05 p.m. Houston time this afternoon, why, the effect has been a net drop; that is, minus 6 points on the industrial average. So far today since opening, the Dow Jones industrial average has gone down by 11.05 after rising 1 1/2 shortly after opening. Today's performance on the utilities is a drop of 1.63, and railroads a drop of 1.58. Over.

Every flight has to have some disadvantages, I guess.

Roger. There is some speculation that you all are responsible for that 1 1/2 point rise right after opening.

Well, don't blame the 11 point drop on us, anyway.

Roger.

Apollo 11, this is Houston. If you have a minute or so free, I wonder if we could get Mike to give us a little bit of clarification on what happened around about the time of docking. We copied him as mentioning that contact was very smooth, almost imperceptible; and we're a little bit inquisitive or curious about his remarks as to what happened after probe retraction. Over.

Roger. I docked in CMC AUTO, and as I said, I wasn't really sure of the moment of contact. I kept cross checking the docking probe indicators. I got two barber poles indicating that the three capture latches—not capture latches, but the three … latches had made, and we were soft docked. And at that time the situation looked very stable. So, I went to CMC FREE, glanced back out the window and it still looked stable; and I fired primary 2 bottle. And at that time, a gyration began between the two vehicles due I'm not sure to what. Perhaps the LM thrusting or perhaps it was building up prior, and I hadn't noticed it. But anyway, during the RETRACT of the probe, there were yaw—my yaw excursions of, I would guess, around 15 degrees, and I had to come back on, take the FREE switch and throw it back to AUTO, and try to damp them out; and I guess Neil was doing the same in the LM. I'll let him tell you about his side of it. And I though that we were not going to get a successful RETRACT and hard dock. However, in about—oh, I guess 6 or 8 seconds, I did hear—could see the situation damping out, and then we heard the noise indicating the docking latches had fired; and later on when I got into the tunnel, all 12 of them had properly engaged.

Roger.

And on the LM side, we were in AGS MIN deadband ATT HOLD; and at contact, I thrusted plus X; and shortly after that we had a sizable attitude oscillation and thruster firing, so we opened up the deadband to MAX and manually flew the vehicle into stable attitude during the retraction. It went to OFF after …

Apollo 11, this is Houston. I have your midcourse correction 5 PAD available when you're ready to copy.

Stand by.

Houston, Apollo 11. Ready to copy.

11, this is Houston. Midcourse correction number 5, RCS/G&N: 26025, pitch and yaw trim NA, TIG 150 29 5453, minus 00048, plus all balls, plus 00001 075 159 328; HA is NA; HP plus 00230 00048 011 00048; sextant star 03 0908 382.

Roger. Midcourse number 5, RCS/G&N: 26025, pitch and yaw NA, 150 29 5453, minus 00048, plus all zeros, plus 00001 075 159 328, NA, plus 00230 00048 011 00048 03 0908 382, NA three times, plus 1102, minus 17204 11803 36275 195 03 33, Deneb and Vega, 007 144 068, and four quads for the burn. Over.

Apollo 11, this is Houston. Over.

Roger. Go ahead, Houston.

Roger. If Neil has a free minute, we've got a question or two regarding the CO₂ partial pressure and water in the suit loop discrepancies noted yesterday. Over.

Go ahead.

Roger, 11. Was water noted in both suits or only in yours, Neil?

I think only in my suit.

Okay. Can you locate that occurrence for us in time when you first noticed water in the suit, either by mission time or relation to any particular event?

I think it was after insertion sometime, Bruce. I don't remember exactly when. I—It was when we were in orbit and had our—after we took our helmets off.

Roger. Did you call it to us when you first noticed it, or was it sometime after when you called it?

I'd guess it might have been probably 20 minutes after I noticed it that I mentioned it to you.

Roger. Was this noticing the water accompanied by erratic CO₂ partial pressure readings, or was that a separate problem? Over.

Well, the water problem evidenced itself before we noted any erratic motions of the PC02 gage.

Roger. And what was the relative sequence on selecting water separator number 2 and the secondary CO₂ canister; that is, did you go to the secondary water separator first and then the secondary CO₂? Over.

I believe we went to secondary CO₂ first.

Secondary hydroxide—lithium hydroxide.

Roger. We copy. And was there any change in your suit loop —

No.

Go ahead.

I should mention, Bruce, that when I went to water secondary—water separator to secondary there, I didn't notice any change. But about after 15 minutes or 20 minutes, the water stopped coming out. So maybe that was just water that was already in the loop that was still blowing out, but the secondary water separator was operating properly.

Roger. Did you make any changes in the suit loop configuration after you went from the egress mode to the cabin mode after insertion; that is, in particular, they're interested in knowing if you recall changing the diverter valve position to EGRESS at any time while you were on the secondary canister? Over.

No. I don't believe we did that at all, Bruce.

Okay, 11. Thank you. That sums up our questions for now, and we'll crank these back into the engineering pipeline and see what we can come up with.
