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 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.
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.
The United States Indo-Pacific Command submitted a report of an unidentified anomalous phenomenon to the All-domain Anomaly Resolution Office (AARO) consisting of nine seconds of video footage from an infrared sensor aboard a U.S. military platform in 2024. The reporter did not provide any oral or written description of the observation.
Video Description:
00:00-00:09: The sensor focuses on an area of contrast that resembles a football-shaped body with three radial projections: one oriented vertically, and two oriented downward at a 45-degree angle relative to the major axis of the main mass.

This audio file records a March 1952 presentation by Captain Edward J. Ruppelt, outlining the U.S. Air Force’s reorganized investigation into unidentified flying objects (UFOs). The presentation previews prospective technical methodologies, such as diffraction-grating photography and radar-scope synchronization, that were subsequently incorporated into Project Blue Book, a U.S. Air Force program active from 1952 to 1969 that investigated the nature and origin of UFOs. Ruppelt explains that out of approximately 800 historical cases reviewed by the Air Force, approximately 20% remained unexplained after technical analysis. These unresolved reports were sourced from credible military personnel, commercial pilots, and other qualified technical observers. He highlights geographic report concentrations around sensitive national security and nuclear weapons installations (including Los Alamos, Albuquerque, and Oak Ridge National Laboratories) and notes recurring anomalous characteristics, including silent high-speed flight and radar detections indicating unconfirmed air speeds between 1,000 and 3,500 miles per hour. Emphasizing that the Air Force found no conclusive evidence regarding the nature or origin of the phenomena, Ruppelt underscores the national security need for a systematic physical data collection effort to better evaluate these sightings.
This archival footage is a digitization of a 16mm print of Kodachrome color motion-picture film shot on a handheld Bell & Howell Auto Master camera near Tremonton, Utah, on July 2, 1952. U.S. Navy Chief Warrant Officer Delbert C. Newhouse reported observing and filming a group of bright airborne objects and shortly thereafter submitted the footage to the U.S. Air Force. The film later became one of the visual cases reviewed by Project Blue Book, the 1952–1969 U.S. Air Force program that investigated the nature and origin of unidentified flying objects (UFOs). The film’s limited detail and lack of fixed reference points prevented a conclusive resolution. From the 55-second mark onward, the film transitions to unrelated footage appearing to show a demonstration of sewing equipment. The presence of unrelated sewing-equipment footage suggests that the surviving footage may be a composite or reused print, though the available record does not establish how or when the materials came to be combined. As documented in records submitted with the film, contained in this collection under the title DOW-UAP-D102, the footage originally was paired with mountain scenery from Idaho, which is not preserved in this digitization.
