Mercury Atlas 9 Audio Excerpt, May 15, 1963
🏛️ NASA
During the final and longest flight of Project Mercury, Mercury-Atlas 9 mission (MA-9) Faith 7 Pilot L. Gordon Cooper Jr. describes the brilliant blue of sunrise beneath the haze layer of the Earth’s atmosphere. As he approaches sunrise, he describes small, luminous, brilliant white particles drifting away from the spacecraft. Cooper describes observing “fireflies” after deploying beacons, which are spherical mission-related equipment with xenon strobe lights.

Mercury Atlas 9 Audio Excerpt, May 15, 1963
NASA
Approximately one hour and 41 minutes into the final and longest flight of Project Mercury, Mercury-Atlas 9 mission (MA-9) Faith 7 Pilot L. Gordon Cooper Jr. notes that he sees “John’s fireflies,” referring to John Glenn’s term from the Mercury-Atlas 6 mission. NASA later determined that the “fireflies” are attributable to frozen condensation separating from the spacecraft body. The white, green-hued appearance of this phenomenon results from sunlight reflecting off frozen condensation.
Mercury Atlas 8 Audio Excerpt, October 3, 1962
NASA
During the Mercury Atlas 8 mission, Sigma 7 pilot Walter M. “Wally” Schirra Jr. describes observing “little white objects that tend to come from the capsule itself and drift off.” Schirra later also refers to those objects as “particles” and “lathe shavings.” Schirra also describes seeing a burst of light in the window, whose source he cannot identify. He speculates that his observation corresponds with the moment the sun passes below the horizon during sunset.
Mercury Atlas 7, May 24, 1962
NASA
During the fourth crewed spaceflight and second orbital flight of Project Mercury, Mercury-Atlas 7 (MA-7), Aurora 7 pilot Scott Carpenter describes white particles in view that appear to move at “random” and “look exactly like snowflakes.” He describes these phenomena as reflective, and that some seemed to move faster than the Aurora 7 spacecraft.
Apollo 12 Medical Debriefing - Tape 12, 1969
NASA
During a medical debriefing of the crew of the Apollo 12 mission, Commander Charles “Pete” Conrad, Command Module Pilot Richard “Dick” F. Gordon, and Lunar Module Pilot Alan L. Bean describe their observations of instances of light flashes or “streaks of lights.” The astronauts each reported that these experiences occurred in the dark as they tried to sleep. The NASA medical team considered whether similar phenomena reported by Apollo 11 Lunar Module Pilot Buzz Aldrin had been attributable to exposure of the retina by cosmic rays. NASA later determined that the phenomena reported by the Apollo 12 flight crew were internal to the astronauts’ vision rather than external light sources.
