NASA-UAP-D015, Astronaut Scientific Debriefings, 1962-1963

Short overview

This NASA-related collection contains memoranda, correspondence, reports, and interview or debriefing material about luminous phenomena reported by astronauts such as John Glenn and Walter Schirra. The Carpenter passage discusses white, snowflake-like objects and whether they were related to sunrise or to the spacecraft capsule. The texts address observations and possible physical explanations, not extraterrestrial evidence.

Why this is interesting

• The collection shows scientific interest in astronaut light and particle observations.
• One passage discusses timing, photography, brightness, and particle size.
• The text includes an experimental observation: striking the capsule wall released particles.
• It therefore distinguishes observed phenomena from a likely technical or environmental source.

Selected passages

• p. 60: Carpenter reported white objects resembling snowflakes, seen at sunrise on all three orbits but also at other times after sunrise.
• p. 60: Some photographed particles are described as considerably brighter than the Moon, with brightness discussed as consistent with centimeter-sized “snowflakes.”
• p. 60: Shortly before reentry at sunrise, Carpenter reportedly hit the capsule wall, promptly releasing large numbers of particles.
• p. 60: The text concludes that at least those particles observed during the MA-6 flight emanated from the capsule.
