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 Crew Debriefing on January 4, 1973, in which astronaut Harrison Schmitt reported seeing light flashes. • Page 24-4. [Lunar Module Pilot Harrison Schmitt]: “We had light flashes just about continuously during the whole flight when we were dark adapted. I had one which I thought was a flash on the lunar surface. That one period of time when we had the blindfolds on for the ALFMED [Apollo Light Flash Moving Emulsion Detector] experiment there were just no visible flashes, although that evening, that night, before I went to sleep, I noticed that I was seeing the light flashes again.”

✦ AI summary

This 2-page excerpt from NASA document MSC-07631, "Apollo 17 Technical Crew Debriefing (U)," dated January 4, 1973 and prepared by the Training Office, Crew Training and Simulation Division, Manned Spacecraft Center, Houston, was originally classified CONFIDENTIAL and declassified under E.O. 13526, Sec. 3.3(a), per the NASA Declassification Guide (dated May 2026, reviewed 5/6/2026). Page 1 is the cover sheet; page 2 (numbered 24-4) contains crew remarks: CMP Ronald Evans says that after a fireball's brightness decreased, he looked back through the rendezvous window and saw what looked like a tunnel with a bright spot in the middle, with the fireball visible further back down the tunnel. Commander Eugene Cernan states the only unusual sighting he recalls during landing or recovery was the CMP looking out the window, seeing the superstructure of an aircraft carrier, and remarking, "Oh, we've got a tin can with us" — i.e., spotting the recovery ship. Evans adds the windows were foggy at the time. LMP Harrison Schmitt reports that during transearth coast they had only a small crescent of Earth visible, not enough for extensive weather observations, and that they experienced light flashes almost continuously throughout the flight while dark-adapted, including one he thought was a flash on the lunar surface; during the period they wore blindfolds for the ALFMED experiment no flashes were visible, resuming that same evening before sleep. These two pages describe light flashes the crew experienced in flight and a routine recovery-ship sighting — no unidentified flying object, craft, or maneuver is described.

Way down the tunnel, way back behind, I could see the fireball. CERNAN: The only unusual sighting I can recall during landing or recovery is when the CMP looked out the window and saw the superstructure of an aircraft carrier and said, "Oh, we've got a tin can with us." EVANS: Well, it was kind of foggy on the windows. SCHMITT: Transearth we had only a small crescent of an Earth and it was not feasible to do any extensive weather observations. We had light flashes just about continuously during the whole flight when we were dark adapted. I had one which I thought was a flash on the lunar surface. That one period of time when we had the blindfolds on for the ALFMED experiment there were just no visible flashes, although that evening, that night, before I went to sleep I noticed that I was seeing the light flashes again. So, it just seemed to be that one interval either side of it where the light flash was not visible to myself or to the other two crewmen. [Classification stamp, struck through]: CONFIDENTIAL
