Provenance and Content
This file contains segment 1 of 2 of the Apollo 14 post-mission crew debriefing at the Manned Spacecraft Center (now Johnson Space Center) in Houston, Texas. In the recording, crew members and debriefers discuss the "light flash phenomena," a then novel effect now understood as high-energy cosmic rays passing through the eye and striking the retina, producing the perception of light streaks or flashes. The questioners work to distinguish the characteristics of what the crew observed. The debriefing continues in the next file, NASA-UAP-D027, which contains some overlapping audio content.34
