Official description

Apollo 17 was the ninth crewed U.S. mission to the Moon, and the sixth to land astronauts on the lunar surface. This document is an excerpt from the Apollo 17 Technical Air-to-Ground Voice Transcription, December 1972, highlighting three periods in which astronauts reported observing unidentified phenomenon: a nine minute period on the first day, a three hour period on the second day, and a six minute period on the third day. • Day 00, Hour 03, Minute 34, Second 10 through Day 00, Hour 03, Minute 42, Second 29: o Command Module Pilot (CMP), Ronald Evans, reported observing “very bright particles or fragments” drifting and “tumbling” near the spacecraft as it maneuvered. Lunar Module Pilot (LMP), Harrison “Jack” Schmitt, described the phenomenon as looking “like the Fourth of July.” The astronauts speculated that the phenomenon may be attributable to ice or paint fragments dislodging from a separated component of the spacecraft (S-IVB) but characterized that assessment as a “wild guess.” • Day 02, Hour 18, Minute 42, Second 34 through Day 02, Hour 21, Minute 07, Second 05: o Mission Commander, Eugene A. Cernan, reported difficulty sleeping and described having observed “some sets of the streaks.” He also described an intense light flashing between his eyes, describing its intensity as comparable to that of a train headlight and characterizing it as “imposing.” Over the next three hours, Cernan described observing several flashing, rotating phenomenon that he assessed as corresponding to physical objects in space rather than a purely optical phenomenon. LMP Schmitt also reported observing similar phenomenon, though he again assessed the source of his observation to be a separated rocket stage (S-IVB). At 02:20:55:22, Cernan reported observing two additional distant flashing objects, though he assessed them as Spacecraft/Lunar Module Adapter panels (SLA panel), another separated component of the Saturn V rocket. • Day 03, Hour 15, Minute 33, Second 25 through Day 03, Hour 15, Minute 39, Second 46: o At 03:15:38:09, LMP Schmitt exclaimed that he had observed a flash on the lunar surface north of Grimaldi (crater).

AI summary

NASA Apollo 17 air-to-ground voice transcript (December 1972), covering translunar coast through lunar orbit. Early pages (Tape 5) describe the crew observing a debris field of bright, jagged, flake-like tumbling fragments after S-IVB separation, discussed with Houston as likely ice chunks or paint peeling off the booster - a mundane explanation offered by both crew and ground. A more notable passage (Tape 46, MET ~02:18) has CDR Gene Cernan describing a distant, definitely non-particle, physically rotating object with rhythmic bright/dim flashing, visible about 10-12 Earth diameters from Earth in the sky; ground (CC) asks for NOUN 20 attitude data and a mark to try to locate it optically, and the crew eventually concludes it is likely the discarded S-IVB stage/SLA panels reflecting sunlight as they tumble, though CDR notes 'no question in my mind but that they're there,' referencing having also seen similar streaks/flashes the prior two nights while trying to sleep. Later, LMP Jack Schmitt reports seeing a bright flash on the lunar surface near the crater Grimaldi and asks Houston to check seismometer data for a possible small impact. Overall the transcript documents phenomena crew and ground largely attributed to known causes (jettisoned hardware, debris, lunar impact flash) rather than unidentified craft.

[PAGE 1] Tape 5/2 CC Yes, we copied your VI and your EMS numbers, and we've got a number for you. Maneuver start time will be at 03 plus 33 plus 27. LMP Okay, we got you. Maneuver at 03:33:27. cc That's affirmative, Jack. LMP You guys didn't tell us we going through the sunrise, couldn't see anything cc (Laughter) Roger. 00 03 25 01 cc 17, Houston. We're making plans here for a spacecraft SEP time of 03 plus 43. LMP 03 plus 43. Roger. 00 03 27 27 cc 17, Houston. We're copying cabin press of 5.9 this time. CMP Roger. We - we just got it, Bob. cc Okay. CMP Thank you. 00 03 31 55 LMP Frame 65 for the LMPs mag November November. 00 03 34 10 LMP Okay. We - we are maneuvering, Houston. cc Roger. We're watching it. CMP Now we've got a few very bright particles or fragments or something that go drifting by as we maneuver. CC Roger. Understand. LMP There's a whole bunch of big ones on my window down there - just bright. It looks like the Fourth of July out of Ron's window. CMP Yes. Now you can see some of them in shape. They're very jagged, angular fragments that are tumbling. [PAGE 2] Tape 5/3 CC Roger. They look like fluid of some sort? CMP Not to me. They look like pieces of something. CC Roger. CMP They're very bright. CC Jack, we'd like OMNI Charlie. CMP Bob, for the most part, these fragments are not - or are tumbling at a very slow rate. I tried a couple of pictures of them - different settings. You may get an idea of what, at least, the patterns look like. CC Roger. I've got you. We're all ears on these fragments. Do you think you can figure out what they might be? CMP Well, you know I - I don't know. There are a number of possibilities. If you had some kind of a - I got the impression maybe they were curved a little bit, as if they might be - off the side of the S-IVB. And that's a wild guess. CDR Okay. RCS LOGIC is ... CMP - ice chunks, possibly. Or maybe there's paint coming off of it. 00 03 37 34 cc Roger. I noticed on one trip up the elevator last week near one of the flags. I thought it was on the S-II, but it might have been on the S-IVB. Looked like it was peeling. Maybe that's what you've got. 00 03 37 45 cc And the S-IVB maneuver is complete. 00 03 37 46 LMP in 1 minute. CDR Okay. We'll set the old clock. CMP Okay. And the - with the maneuver complete, the fragment field is essentially static, except for very slight tumbling within the fragments. [PAGE 3] Tape 5/4 00 03 38 01 cc Roger. Cut in. CMP Every once in a while, a fragment of considerably higher velocity than the others goes across my window. But that's very rare. CC Roger. CMP Hey, that's that field of view I saw out my window. Jack, do you see it now? LMP Yes. CMP And, Bob. At least, there's no apparent relative motion between fragments. CC Roger. Understand. CMP I'll take two pictures about a minute apart if I can. And it'll be Frame 70. CC Okay. Frame 70. CMP And, Bob. This is Gene. My impression is that they are flat, flakelike particles. Some may be 6 inches across. And, although there's no relative motion between the two, most of them seem to be twinkling. And I think, for the most part, they're all moving away from us. CC Roger, Gene. Thank you. 00 03 39 35 cc Okay. We've got 0180 and 0 on the old thumbwheels. 00 03 39 53 cc Okay. Roger, Ron. 00 03 39 57 CDR Okay. TRANS CONTROL is ARMED . . . two ARMED. CONTROLLER number 2 is ARMED. SECS LOGIC ... [PAGE 4] Tape 5/5 00 03 40 01 CMP Okay. SECS LOGIC is CLOSED; LOGIC POWER is ON; SECS ARM are CLOSED. LMP Okay. 00 03 40 13 cc 17, Houston. You have a GO for T&D. CDR Okay. A GO for T&D. 00 03 40 38 CMP Okay. ALIGN. We'll ARM the PYROs. And we'll hit the GDC. 00 03 41 00 CMP And maneuver's complete. GDC? No. It's just ... And 0180 and 0? On the ... It's kind of diddling. 00 03 41 19 CMP Okay. DELTA-V in NORMAL. 00 03 41 42 CMP S-IVB, okay. Okay, switches are all set. LMP Okay; 59:30. 00 03 41 55 CMP Okay. Let's start the DET. 00 03 41 59 CDR Tickity-tick-tickity, Houston. We're running at 59:30. cc Roger. CMP Okay. 00 03 42 12 CMP Okay. That's LAUNCH VEHICLE SEP, push button. LMP Okay. 00 03 42 19 CMP MC in AUTO. CMP Next? 00 03 42 29 CDR SEPARATION, Houston. CMP Okay, check the other ones off, covers. Okay. And check the ... LMP They're all ... CMP Okay, I'm going to start the - My gosh, look at the junk! Okay; there's 15 seconds. Pitch her up. Okay, we'll PROCEED on the - - [PAGE 5] Tape 46/4 02 18 41 11 CDR/CMP Okay. Is that it? Yes, I can get that, Gene. Okay, you want to take a picture of it first? Okay, POWER ... Okay, stand by. 3, 2, 1 - MARK it. POWER switch OFF. 02 18 41 59 CMP Say, Bob or Stu. cc Roger. Go ahead. 02 18 42 34 CDR Okay, add - to today. Not last night, but - I guess the first night I was in bed - I definitely saw some of these - because I had a hard time going to bed, to start with - I saw some of the same peripheral horizon-type things you said were not the type of data you were looking for; but I also saw a - some sets of the streaks. And probably the one most imposing thing I remember is - and the last one I remember before falling asleep - was the fact that there was a very bright spot that flashed right between my eyes like a very bright headlight - like a train coming at you, only with a flash. It's difficult probably to estimate the frequency of any of those because I was in a - sort of a sleep-hazy mode. CC Roger. CDR But then, as today, I saw some that flashed and lit up the horizon and some that lit up peripherally; and I guess, as you say, that's a different kind of data, but I did see them there and they impressed me. CC Okay. We got all that, Gene. CDR Okay. And it might be interesting to know I've never seen it before today. CMP Hey, Gene, we appreciate all the data. We were just trying to make the data fit the curve; you know the old trick. [PAGE 6] Tape 46/5 02 18 44 40 CDR Okay, I just wanted you to know - just told them like we saw them. That's all. CC Roger. CDR I will say one thing, though; no question in my mind but that they're there. Last trip I took, I guess I just wasn't looking for them or paying any attention to them. Maybe they were there and I ignored them because of other things. But they're there. LMP Okay, all you flash bugs down there - or flash bulbs I guess is the word - frame 50. I just took four pictures to show - two on the side and two on the bottom - to show the position of the ALFMED, and one of them of each set was focused on the ALFMED. The others were focused on the - the other set was focused on the struts. CC Roger, Jack. LMP And when you don't have anything else to do, why don't you have somebody predict where the S-IVB is. I think I've got her spotted - behind us and above us with respect to the Earth and our travel from it. CC FIDO just went and shot himself, but we'll get working on it. LMP Oh, don't worry about it. Shoot. I thought you guys might have an idea off-the-cuff there. CC No, what's humorous on this, Jack, is they have really been working on that S-IVB impact point - and it's been a real difficult problem for them so far. LMP I'll tell you, I bet you Ron could give a star sighting on it (laughter). I looked at it through the monocular and sure looks like the S-IVB. CC Jack, we're not doubting you at all. We could probably start cranking it right now. [PAGE 7] Tape 46/6 02 18 46 46 cc Jack, are you all done with the ALFMED now, Ron? CMP Yes, I've got to get it to - get the plate moved back down there yet. CC Okay, Ron - get the blindfold off first so I can see what I'm doing. CMP Roger. I just want you to know. We've got a real long update coming up to you here on the LOI abort charts - and it's going to be, probably, a difficult readup. And you're the most familiar with the charts; you probably would want to take them. But whenever you want to take them, they are on charts on page 3-81, 3-82, and then the cue card for LOI limits. Whenever you want to take them. It will be a lengthy one. CC Stand by, Bob. Let us get squared away from the ALFMED; then we can get going on that. CMP No, I don't want to hurry you, Ron. I just want you to know what - when - just get yourself comfortable and be ready to take them whenever you want them. It's going to be a lengthy time, though. 02 18 47 51 CMP Okay. Hey, Bob, I'm looking at what Jack was talking about; and it's definitely not a particle that's nearby because there is another one I can look at and get a three-dimensional comparison with. It is a bright object, and it's obviously rotating because it's flashing. It's way out in the distance, as I say, because there are particles that are close by and it's obviously not one of those. It's apparently rotating in a [PAGE 8] Tape 46/7 CC ... very rhythmic fashion because the flashes come around almost - almost on time. And as we look back at the Earth, it's up at about 11:00 - about, oh, maybe 10 or 12 Earth diameters. I don't know whether that does you any good, but there is something out there. 02 18 49 02 CDR Roger. We don't doubt it, Gene. And we might work out a set of gimbal angles or something here; maybe we can get a look at it through the optics. 02 18 50 13 SC Okay. And I - I just want to emphasize that it's definitely not - not one of these particles that tends to look like a star out there. It's something physical in the distance. CMP (Laughter) Oh, yes, thing off. Yes, guess I am. CC Okay, Gene. If you can call up a NOUN 20 so we know the spacecraft attitude, and if you can reference the object you're looking at out of your window, with respect to body axis and let us look at your NOUN 20s, we can try and get a tie-in and start locating this object down for you. 02 18 50 58 CDR Okay, I'm looking at it out the center window - the hatch window - and I'll give you a hack when it crosses the XX axis at the center window; and I guess it's up maybe 45 degrees. CC Okay, give us a hack and we're copying your NOUN 20s right now. CDR Okay, Jack says pitched up about 30 degrees but - - LMP No. 45, because - CDR Yes, he agrees. It's 45 degrees pitched up, and I'll give you a hack when it crosses the XX axis. CDR Okay - [PAGE 9] Tape 46/8 02 18 51 32 CDR MARK it. It just crossed through the - - CC Mark. We got it. Let's call it the XZ plane of the spacecraft. CDR One unique thing about it, Bob, is that it's got two flashes. As it comes around in a rhythmic fashion, you get a very bright flash; and then you get a dull flash. And then it'll come around with a bright flash, and then a dull flash. 02 18 52 18 LMP That's the side and of the S-IVB - and then the engine bell, Gene. The commander doesn't think that I can see the engine bell on that thing. 02 18 53 10 cc Roger, Jack. Is that with the monocular you're looking at it? CDR He couldn't see the engine bell if he had 10 monoculars. CMP Okay. I've got the cable restowed now. 02 18 55 24 cc Say again, Ron. CDR And, Gene, where's your blindfold? CMP Bob, a couple of revolutions ago when I was looking at it, I had a much brighter view and I believe I was looking at it broadside. It looks to me like it may be flashing more or less end-on now. It's not as bright, although it's getting brighter. But it's not as bright now as it was awhile ago. cc Roger, Jack. LMP We've been noticing that, I think, for about 24 hours or so. I just hadn't put it together as maybe being the S-IVB. I thought it was just some other particle out there. 02 18 56 27 cc Roger, Jack. Hey, Robert, what's the final Cowboy score? [PAGE 10] Tape 46/9 CC Okay; I was just going to update that. The Cowboys won it 34 to 24. And by winning it, they wrap up the wild-card slot in the NFC; and so both Washington and Dallas will be in the playoffs. 02 18 56 53 CDR Sounds good. LMP Bob, that line of clouds I called a fir-tree pattern that swings up towards Hawaii - has also has a mushroom pattern on the top. It has the appearance as if two major air masses - one going from west to east and the other from east to west - have converged along that line, and the joint movement of air at the interface being south to north. And up in the area of Hawaii, I think, it tends to mushroom so that the pattern then goes back to flow from west to east on the east side and from east to west on the west side. CC Roger. 02 18 58 27 LMP In a little while, we'll probably get a pretty good look at what looks like a very concentrated intense storm that, I think, is just east - CMP And then we'll put them, once we get updated a little bit. Yes, I'll get out of VOX in a minute. LMP I was looking for the Flight Plan and stuff. And the little books. LMP Say, Bob. CC Go ahead. LMP Houston, 17. How do you read? CC Go ahead, Jack. Read you loud and clear. CDR Okay, Bob, you want to update the LOI card and Flight Plan 3-82 and 3-81; is that right? CC That's affirmative. CDR Which one do you want to start on? [PAGE 11] Tape 47/14 [LMP] And I'll just confirm that the disturbance over the Solomon Islands is an awfully tightly wound little storm system. And right now, I finally see New Zealand for the first time in a couple of days, for sure. And the South Island's got some, probably high cirrus over it. North Island looks pretty clear. That's the end that I can get right now. CC Roger. We saw you looking at Regulus there; we didn't realize you were looking at the Earth instead. LMP Ron's been looking for the booster. And he called me down and asked me to look at the Earth. He's been holding out on me. CC Roger. LMP Pass the torch of weather forecasting to Ron. 02 20 55 22 cc Hey, Jack. I also have some words for you and Gene. Got some advice from the home front. The thing to do with Ron in the future is to hook up a Baby Ben and a metal dishpan. It works every time, if you want to wake him up. CMP No. I think that's not a good way. CC Ron, everybody is fine over at El Lago. They are doing great. Listening to every word. CMP Very good, Bob. Thank you very much. CDR Hey, Bob. We got two of those flashers out there. They could be SLA panels. I don't know. They're alike in intensity and pretty regular in the intensity, bright and dim flashes they come out with, and they're widely separated. One is about the position we called at the first time; the other one is - oh, as I'm looking at the Earth, far to the left. Closer to the center window now. 02 20 56 52 cc Roger. 02 21 01 07 LMP Houston, 17, [PAGE 12] Tape 47/15 CC Go ahead. LMP Yes, Bob, what is your - have it - surface terms Hawaii today? CC Stand by on that. Jack, according to the analysis chart show for - LMP The reason I ask is that for - using your term - CC No, go ahead on that, Jack. LMP I was going to say, using your terminator time as a partial mark for where Hawaii ought to be, it looks like that cyclonic circulation at the north end of the cloud bank I described, approaching that area, would be just about on the Hawaiian Islands. I'm curious if they're getting some weather down there now. CC Stand by right now; I've got my weatherman right beside me here. LMP Also, that major front we talked about last night as being east and south of Japan has progressed even farther and is, oh, maybe 20 degrees longitude from the Hawaiian Islands. And I'm making some guesses on exactly where Hawaii is. CC Roger, Jack. We've got nothing adverse in the Hawaiian area at all. Just a lot of winds, high winds and surface winds and surface roughness, but we don't have any bad cloud area in the Hawaiian area. I'll get the Hickam sequence report here shortly, Jack. LMP Okay ... The - our zero-phase point is now centered just a little south of the disturbance near the Solomon Islands. And I see no distinct change in the intensity of that zero phase point over what I had talked about a couple hours ago. [PAGE 13] Tape 47/16 02 21 04 23 cc Roger, Jack. The Solomon Islands disturbance and everything is confirmed on this chart that I've got. It's very definitely confirmed in there. LMP Okay. Well, it's a lot more obvious today than it was yesterday; but even then it was showing pretty strong circulation. It is starting to wrap up, look very much like Therese did yesterday. CC Roger. I'm sure of that. The one right off of Vietnam is also pretty tight, isn't it still? LMP Well, we can't see that one yet. CC Okay. LMP Australia in general is still very clear except in the northeastern portions where it looks like they have got scattered clouds; but it looks like a pretty night - over Australia. CC Roger. Looks that way from the satellite photo from the last couple days. Looks pretty nice down there. 02 21 05 34 LMP Right. 02 21 07 05 cc Jack, in looking at the sequence reports for Hickam and Hilo and that area, it looks like they just got their standard 3500 scattered, 4500 broken clouds, maybe a rain shower or two. But just their standard tropical fluffy clouds. END OF TAPE [PAGE 14] cc 03 15 33 25 LMP Tape 59/19 mare. Still looking at Oceanus Procellarum. And now, out window 3, up to the northwest, Grimaldi is starting to show up - a very obvious dark area within the highlands of that part of the Moon - and one of the darkest mare regions that we have seen on the Moon. It's comparable, at least in the photographs, to that of Tsiolkovsky. CC Roger. Normally, of course, we think of the dark mare as being the younger basalt flows on the Moon, but in our case, of course, young means something on the order of 3 billion years or older. END OF TAPE [PAGE 15] Tape 60/1 APOLLO 17 AIR-TO-GROUND VOICE TRANSCRIPTION 03 15 33 44 cc Roger. LMP For our interpretation - if we can extrapolate from the samples returned by other missions. LMP Amazing how far over - now the highlands to the west of Procellarum are still bright, and the contrast between fresh craters and the normal highland are very obvious still in earthlight, particularly along the zero phase point with respect to the Earth. Rima Gamma now is coming a little bit closer to our oval track in the horseshoe in the larger and more western end of it; the dark horseshoe is quite clear in this light. It's a west- or northwest-pointing horseshoe, as is the complete trend of that strange feature. I think Ron is going to have an excellent chance to study these light-colored swirls within the mare and other parts of the Moon. We had some good views of them in Mare Marginis and to the east of Crisium - Mare Crisium, and he should be able to see it for during the next few days. CC Okeydoke. 03 15 35 50 CDR Say, Gordo, something I just noticed here in working with the GDC. I looked at the Pc gage, and in the Pc position, there is a continuous bias on it now of about, oh, 7 percent, and if I switch to ALPHA, it goes to zero. We never saw that bias before this last burn. CC Roger, Gene. 03 15 36 35 LMP Hey, Gordy, I'm looking right up the western edge of the Procellarum mare where it contacts the western highlands of the Moon, and we're just about to fly a little bit south of Grimaldi. That edge is very irregular. There are no obvious indications that there are large basins that have been flooded by mare that have formed that edge, but the topographic distinction's possible in this light. Now I'm starting to see that there are shadows in the craters. [PAGE 16] Tape 60/2 CC Roger. LMP That's the small craters. There, in the Mare Procellarum closest to Grimaldi, there are two arcuate rilles. Look like they are probably V-shaped in their cross section. I'm sure we've seen those on the photographs much better than I can see them here. Those rille patterns, though, do seem to project over into the highlands. CC Okay. LMP To the north of that - to the north of that bay of mare. Just interrupt. 03 15 38 09 LMP Hey, I just saw a flash on the lunar surface! CC Oh, yes? LMP It was just out there north of Grimaldi. Just north of Grimaldi. You might see if you got anything on your seismometers, although a small impact probably would give a fair amount of visible light. CC Okay. We'll check. LMP It was a bright little flash right out there near that crater. See the crater right at the edge of Grimaldi. Then there is another one north of it. Fairly sharp one north of it is where there was just a thin streak of light. CC How about putting an X on the map where you saw it. LMP I keep looking occasionally for - yes, we will. I was planning on looking for those kind of things. Starting to see the edge of Orientale, Gordy. Way off to the west. Hey, just yell, Gene, anytime you - - 03 15 39 46 LMP Gordy, to the north of Grimaldi there is a large basin that is about the same size but only incompletely filled with mare in its northeastern quadrant. The rest of it looks like a fairly irregular and hummocky floor material of some kind. CC Roger,
