WHAT THE RECORD SAYS
The government's own description, as released.
This file contains segment 1 of 2 of the Apollo 17 post-mission medical debriefing at the Manned Spacecraft Center (now Johnson Space Center), Houston, Texas. In the recording, crew members discuss the “light flash phenomena,” a then novel, now well-documented biological effect where high-energy cosmic rays pass through the eye and strike the retina, causing the perception of light streaks or flashes. Two of the three crew members reported observing these flashes at various points during the mission, including in lunar orbit and while on the lunar surface. The debriefing continues in the next file (NASA-UAP-D029).
