Apollo 16 Scientific Debriefing, 1972 — NASA Audio (NASA-UAP-D024)
This debriefing includes presentations from principal investigators of various Apollo experiments. The principal investigators describe preliminary results of their work to educate the Apollo crews about what they’ve obtained from Apollo 16 to help prepare for Apollo 17.
Incident Overview
In 1972, in Houston, Texas, NASA preserved an audio recording that was declassified and published on June 12, 2026 as part of the third tranche of the Department of War’s Presidential Unsealing and Reporting System for UAP Encounters (PURSUE).
What the government released
This debriefing includes presentations from principal investigators of various Apollo experiments. The principal investigators describe preliminary results of their work to educate the Apollo crews about what they’ve obtained from Apollo 16 to help prepare for Apollo 17. They also describe anomalies, such as a “flash” that was observed that had not yet been reported. The flash is mentioned beginning at 25:15.
Status of the case
Records released under the PURSUE program are designated unresolved by the All-domain Anomaly Resolution Office, which means the federal government has not concluded the events were anomalous, has not concluded they were conventional, and has not ruled out either possibility. Where AARO has offered a likely source for an item — an infrared sensor aboard a military aircraft, a commercial camera, or a known optical effect — that attribution is the agency’s working assessment rather than a final determination. Conventional candidates such as drones, balloons, flares, satellites, parallax and forced-perspective artifacts, and ordinary aircraft remain on the table for any unresolved case absent better data than a single sensor pass or a witness recollection.
