Apollo 17 Transcript, 1972

This NASA document contains excerpts from the Apollo 17 air-to-ground voice transcription from 1972. The crew reports bright, jagged fragments drifting past the spacecraft after S-IVB separation, and later describes a distant flashing, rotating object that Jack thinks is the S-IVB. Gene also describes light flashes he saw with his eyes closed. Other passages cover weather over Hawaii and the Solomon Islands, and a flash seen on the lunar surface north of Grimaldi.

From the source: Release of 2026-05-08 Incident: 1972, Moon. 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).

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 Wash
ington 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 pat
tern that swings up towards Hawaii: Hawaii, if
you will - has - also has a mushroom pattern on
the top. It has the appearance as if tvo major
air masses - one going from west to east and the
other form 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 a - what looks like a very concen
trated intense storm that, I think, is just - east -
CMP *** And then we' 11 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?
