During the recovery of the fourth launch and second crewed spaceflight of Project Mercury, Mercury-Redstone 4 (MR-4) Liberty Bell 7, the recovery team discusses a dye pack in the water that did not activate.
This NASA file of astronaut scientific debriefing papers from 1962 collects internal Office of Space Sciences material on the science observations made on early Mercury flights. A February 1962 memo from Maurice Dubin asks for more detail on John Glenn's report of luminous particles and the atmospheric horizon layer. A draft memo concludes that the particles were tied to the spacecraft and were not extraterrestrial. The file also holds a Los Alamos letter that attributes the high haze layer to nitrogen peroxide, and notes on Carpenter's airglow observations.
In November 1962, journalist Walter Cronkite interviewed astronaut Gordon Cooper. In this excerpt from that interview, Cronkite asks Cooper about his views regarding the nature of unidentified flying objects, having previously expressed an interest in the subject. Cooper opines that “a large number of exceptionally well-qualified people have seen objects” without a “logical explanation” and speculates on the existence of other planets with “a livable atmosphere” and that maybe there are “some type of human life” out there. Interview was conducted in November 1962.
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.
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.
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.
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.
This NASA file from 1965 combines Mission Operation Report M-913-65-04 on the Gemini 4 (GT-4) flight with related correspondence. Memoranda from the Associate Administrator for Manned Space Flight describe the planned four-day mission with James McDivitt and Edward White, including a spacewalk, a rendezvous with the booster second stage and thirteen experiments. Later letters and telegrams from NASA's Manned Space Science office concern the astronaut debriefing and requests for GT-4 photography and film for scientific analysis.

This audio recording contains air to ground communications and the NASA Public Affairs audio feed with commentary, recorded during the flight of the Gemini 7 mission. In this excerpted segment of audio, Astronaut Frank Borman reports to NASA mission control in Houston his sighting of an unidentified object, which he referred to as a "bogey." This sighting occurred on December 5, 1965. The dialogue includes Borman's initial report, as well as additional comments by Astronaut Jim Lovell, Borman's fellow crew member.
This NASA transcript of Public Affairs Office release commentary for the Gemini 7/6 flight is dated 5 December 1965 and comes from tape T-00763. In the exchange with Houston, Frank Borman reports a bogey at ten o'clock high, hundreds of small particles passing three or four miles away and the booster in sight. Jim Lovell describes the booster as a brilliant, slowly tumbling body. The Public Affairs Office notes that the flight had reached 4 hours 24 minutes.
This 1966 NASA file collects memoranda by Jocelyn R. Gill of the Manned Flight Experiments Office, plus related correspondence, on the scientific experiments of the Gemini IX mission. Status reports from March and June 1966 describe the zodiacal light, airglow, micrometeorite and synoptic photography experiments, and an experiments debriefing held June 16. The file also contains a congratulatory telegram to astronauts Stafford and Cernan and a Naval Research Laboratory letter on the S-9 cosmic ray experiment. It reports no unidentified objects.
This is the Apollo 11 Technical Crew Debriefing, dated July 31, 1969 and prepared by the Mission Operations Branch, Flight Crew Support Division of the National Aeronautics and Space Administration. It is a confidential transcript. In it, Armstrong, Aldrin and Collins describe a bright L-shaped object seen about a day out from the Moon, which they could not identify and suspected came from the spacecraft. They also report light flashes inside the cabin and a bright light from Earth that was probably a reflection off a lake.
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.
This NASA document is part of the air-to-ground voice transcript of the Apollo 12 mission in 1969, covering tapes 90 and 93. It records routine exchanges between Houston and the crews of the command module Yankee Clipper and the lunar module Intrepid about state vector uplinks, lift-off time, battery charging and rendezvous tracking. One crew member reports flashes of light and particles that appear to stream away from the Moon. Houston attributes a pulsing AGS display to probable electromagnetic interference, and the crew concludes that the LM tracking light has burned out.

This file contains segment 2 of 2 of the Apollo 14 post-mission crew debriefing at the Manned Spacecraft Center (now Johnson Space Center), Houston, Texas. In this continued segment, crew members and debriefers further 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.
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.
This NASA document contains excerpts from the Apollo 17 air-to-ground voice transcription from 1972. The crew reports bright, jagged fragments drifting past the spacecraft after S-IVB separation, and later describes a distant flashing, rotating object that Jack thinks is the S-IVB. Gene also describes light flashes he saw with his eyes closed. Other passages cover weather over Hawaii and the Solomon Islands, and a flash seen on the lunar surface north of Grimaldi.
As part of the review of historical UAP materials under PURSUE, DOW has opened a case to investigate the accompanying NASA photograph from the Apollo 17 mission, taken December 1972. The image contains three “dots” in a triangular formation in the lower right quadrant of the lunar sky that is clearly visible upon magnification of the image. While this photo has been previously released and discussed by keen observers, there is no consensus about the nature of the anomaly. New preliminary US government analysis suggests the image feature is potentially the result of a physical object in the scene. Additionally, as part of this investigation, the government has obtained the original film from the Apollo 17 mission and the results of the full NASA and DOW analysis will be released when completed.
During the eleventh and final crewed mission in the Apollo program, Apollo 17 Commander Gene Cernan, Lunar Module Pilot Harrison Schmitt, and Command Module Pilot Ronald Evans report seeing small lights outside the Apollo spacecraft during transit to the moon. The crew describe bright “particles” or “fragments” as being “jagged,” “angular,” and drifting near the Apollo spacecraft and the separated Saturn S-IVB stage. The Apollo 17 crew speculate that paint chips or ice chips are likely the source of these lights and note that they “twinkle” and move away from the Saturn S-IVB stage.

This is the Apollo 17 Crew Debriefing for Science, document MSC-07632, issued by NASA's Manned Spacecraft Center in Houston and dated January 8, 1973. The extracted pages record a scientist named Henry reporting ultraviolet spectrometer results. These include a search for ionized hydrogen in the Coma cluster that found none. They also cover ultraviolet light at high galactic latitudes, possibly reflected by interstellar dust or extragalactic in origin, and Lyman-alpha hydrogen inside the solar system. The pages contain no UFO content.
The Training Office of NASA's Crew Training and Simulation Division at the Manned Spacecraft Center in Houston prepared this Apollo 17 technical crew debriefing, dated January 4, 1973. The extract covers Evans describing a fireball seen through the rendezvous window. Cernan says the only unusual sighting he recalls during landing or recovery was the CMP spotting an aircraft carrier's superstructure. Schmitt reports light flashes nearly the whole flight while dark adapted, with none seen during the ALFMED blindfold period.
This NASA Lyndon B. Johnson Space Center release collects excerpts from the Skylab 1/2, 1/3 and 1/4 technical crew debriefings, dated June 30, 1973, October 4, 1973 and February 22, 1974. The Skylab 2 crew describe light flashes they saw with their eyes closed and link some of them to cosmic particles. The Skylab 3 crew describe a bright reddish, rotating object that they tracked for about 10 minutes in an orbit close to their own and ask to have it identified. The Skylab 4 crew report lights outside that they took to be Skylab debris or other satellites.
During STS-80, between November 19 and December 7, 1996, astronauts aboard Space Shuttle Columbia captured a series of three images of an unidentified object in low-Earth orbit. In the first photograph, the object is visible near the center of the frame, to the right of the limb of the Earth.
