Why it matters

NASA-UAP-D6, Apollo 17 Technical Crew Debriefing, 1973 is an officially released 2-page record with searchable page text, page-specific claim locators, dated events where supported, and document-level provenance.

Corroboration

The release establishes official provenance for NASA-UAP-D6, Apollo 17 Technical Crew Debriefing, 1973, but its reported observations, judgments, and interpretations remain source claims unless supported by independent records.

Open questions

  • Which companion records or contemporaneous sources, if any, independently corroborate the document’s key claims?

Probed separates this editorial assessment from the source claims below. It summarizes what the released artifact supports; it is not independent verification.

Official Description from War.gov

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.”
