NASA-UAP-D1, MISSION TRANSCRIPT, APOLLO 12, NOVEMBER 1969

This document contains mission transcripts from the Apollo 12 lunar landing mission. The crew reports anomalous light particles, floating debris, and intermittent display malfunctions on the Abort Guidance System. Ground control evaluates these observations as potential electromagnetic interference or standard operational anomalies.

05 19 14 58 CC That's affirmative. We're ready for the E-MOD.
05 19 16 31 CC Intrepid, Houston.
05 19 16 35 CDR-IM Go.
05 19 16 37 CC If you will give us P00 and ACCEPT, we'll give you a CSM state vector and RLS update.
05 19 16 45 CDR-IM You have P00 and ACCEPT.
05 19 20 05 CMP Hello, Houston; Yankee Clipper.
05 19 20 09 CC Yankee Clipper, Houston. Loud and clear.
05 19 20 14 CMP Well, hello there, stranger. How are you?
05 19 20 22 CC Morning, Dick. We are fine. How are you?
05 19 20 27 CMP Well, pretty good. I hope you would like to have some company for a change.
05 19 20 31 CC Roger. Got the house clean?
05 19 20 36 CMP As a matter of fact, I just finished that. I sure do; got everything in order; ready to go towards the LM and bring back ... That's quite a chore; keeping this thing clean.
05 19 20 53 CC Roger. You got a couple of coal miners coming up to see you.
05 19 20 59 CMP That's okay. I'll be glad to see them.
05 19 21 10 CC Intrepid, Houston. The computer is yours. Break. Yankee Clipper, if you will go P00 and ACCEPT, we have an uplink.
05 19 21 20 CMP All yours.
05 19 23 14 CDR-IM Houston, you got the lift-off time for me?
05 19 23 20 CC Stand by.
05 19 23 39 CC Intrepid, Houston. Your lift-off time is 142:03:47.
05 19 23 52 CDR-IM I copy 142:03:47.00.
05 19 23 57 CC Affirmative.
05 19 24 05 CC Clipper, Houston. Computer's yours.

transcript

A transcript of communications between Apollo 12 crew members and Houston, including a report of unidentified light particles observed by the Lunar Module Pilot.

05 19 24 11 CMP Okay. And Jerry, will you find out what they want to do about this battery charge, because I'm using the bus ties during the rendezvous?

05 19 24 23 CC Roger.

05 19 24 43 CC Yankee Clipper, Houston. Why don't you figure on terminating the battery charge at LOS?

05 19 24 52 CMP All right; I could let it go until I ... just before lift-off. That way it might take it all the way up.

05 19 25 33 CC Clipper, Houston. We prefer that you terminate at LOS on this pass.

05 19 25 40 CMP Roger.

05 19 25 41 CC Roger. That would be one less thing for us to keep track of prior to lift-off.

05 19 25 48 CMP Okay.

05 19 27 17 CDR-LM Say, Houston; Intrepid.

05 19 27 20 CC Intrepid, Houston. Go.

05 19 27 25 LMP-LM Roger. When you look out the AOT in the dark quadrant? You can see these lights - particles of light, flashes of light just seem to come from - in this case, I'm looking in quadrant 1 which is the left one. It's coming from behind me, the left, and they're just sailing off in space. I was thinking they're dropping from my water boiler, but it looks like some of those things are escaping the Moon. They really haul out of here and just press off at the stars.

05 19 27 56 CC Roger.

05 19 28 25 CC Yankee Clipper, Houston with a P22 tracking PAD.

05 19 28 42 CMP Go ahead.

05 19 28 44 CC Roger. Your target is LM; T1 is 139:57:39; T2 is 140:02:38; south 05; latitude is minus 3 - -

05 19 29 10 CMP Roger. T 112 -

transcript

A transcript from the Apollo 12 mission where the crew discusses an anomaly on the AGS (Abort Guidance System) display, which ground control identifies as likely EMI (electromagnetic interference) seen during previous testing.

05 20 08 23 CC Clipper, Houston. We'll give that data a good evaluation before we do anything with it.

05 20 09 25 LMP-LM Houston, Intrepid.

05 20 09 30 CC Intrepid, Houston. GO.

05 20 09 34 LMP-LM Got sort of an interesting thing going on AGS right now. I didn't notice earlier, but it may just be because the lights are brighter now. I'm getting an all 8's flash on both the address and the information registers at about one-fifth the brilliance of the normal numbers. And a - It's pulsing every second.

05 20 10 00 CC Roger, Al.

05 20 10 06 LMP-LM If I turn down the illumination level just a little bit, it's not noticeable.

05 20 10 52 LMP-LM Hello, Houston; Intrepid. You ready for my RCS hot fire?

05 20 10 59 CC Intrepid, Houston. Roger. Fire away.

05 20 11 03 CDR-LM Okay.

05 20 11 32 CC Intrepid, Houston.

05 20 11 37 LMP-LM Go.

05 20 11 39 CC Roger, Al. Fredo is here. He and I have both seen that phenomena on your DEDA during testing of most all the spacecrafts up at Bethpage, and it's probably an EMI.

05 20 11 56 CDR-LM That's what we've been talking about, but we thought we'd just touch in on it.

05 20 11 59 LMP-LM When you go to your roll rate, roll left, pitch up - -

05 20 12 01 CC Roger. I think TRW's got a workup on this problem.

05 20 12 08 CDR-LM Okay?

05 20 12 11 CDR-LM Here you go, Houston, with roll, pitch, and yaw.

05 20 12 14 CC Roger, Pete.

transcript

A transcript from the Apollo 12 mission involving communications between the Command Module Pilot (CMP), the Lunar Module Pilot (LMP-LM), the Commander (CDR-LM), and Houston (CC) regarding a malfunctioning tracking light and the observation of floating debris.

06 00 21 42 CMP But I don't have you in the sextant. That's
okay. Your blinking light's just not blinking,
that's all.

06 C0 21 51 CDR-LM Hey, Houston. It looks like our tracking
light's burned out. Dick hasn't been able to
find us in this sextant. And on the first
nightside pass we had little bits and pieces
floating along and we could tell that
the tracking light was flashing on them. And
we still have, I've presumed to think, bits
and pieces floating along and nothing's flashing
on them, so I'm pretty sure it burned out.

06 00 22 11 CC Roger, Pete.

06 00 22 22 LMP-LM Yes, sir. Okay.

06 00 22 26 CC Hi, Intrepid.

06 00 22 27 LMP-LM Okay.

06 00 22 28 CC This is Houston. How'd your sweepdown fore
and aft go?

06 00 22 33 CDR-LM It's getting much cleaner in here running this
way; and, also, Yankee Clipper informs me he
has the television all set up. When we come
around the horn, we'll come around with the
television on in VOX.

06 00 22 47 CC Roger.

06 00 22 53 CDR-LM Who knows, you may get to see the first
whifferdill.

06 00 22 59 CC Roger, Pete. Our electrical watchers say that
the current indicates that your tracking light
is on.

06 00 23 11 CDR-LM Okay. Now we just turned it off. Now does the
current show that?

06 00 23 19 CC It - It sure does, Pete.

06 00 23 26 CMP You're - they're - You're flying through the
air backwards, then, Pete, because I don't see
it.

06 00 23 33 CDR-LM Well, my ball tells me I'm pointed at you, Dick,
and so does my radar.
