NASA-UAP-D026, Apollo 14 Debriefing, 1971

Official Conclusion

Light flash phenomena attributed to high-energy cosmic rays passing through the eye and striking the retina; a biological effect, not an unidentified aerial phenomenon.

Official Description

This file contains segment 1 of 2 of the Apollo 14 post-mission crew debriefing at the Manned Spacecraft Center (now Johnson Space Center), Houston, Texas. In the recording, crew members and debriefers 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. The questioners attempt to distinguish the characteristics of the observed phenomena. The debriefing continues in the next file (NASA-UAP-D027), which contains some overlapping audio content.

Key Findings

• →The Apollo 14 crew reported experiencing 'light flash phenomena' during the mission, which is the subject of the debriefing discussion.
• →The light flashes are identified as a biological effect caused by high-energy cosmic rays interacting with the retina, not an external aerial phenomenon.
• →Debriefers attempted to characterize the specific qualities of the observed light flash phenomena to better understand the effect.
• →This is segment 1 of 2; the debriefing continues in file NASA-UAP-D027, which contains some overlapping audio content.
• →The phenomenon is described as 'then novel' but now well-documented, indicating it has since been scientifically explained.
