May 24, 2026 — cybernewschronicle.com — The Department of Defense, through the All-domain Anomaly Resolution Office (AARO), has released a newly declassified report from 1961 concerning an unidentified anomalous phenomenon (UAP) observed during NASA’s Mercury-Redstone 4 mission. The document, designated D014, was originally classified by NASA and has now been made public as part of the Pentagon’s ongoing transparency efforts under the PURSUE policy framework. The report describes an event that occurred on July 21, 1961, during the suborbital flight of Mercury-Redstone 4, which carried astronaut Virgil I.
“Gus” Grissom. According to the document, the sensor platform—the spacecraft’s onboard instrumentation—recorded an anomalous return at an unspecified location.
The report does not specify the exact nature of the anomaly, but it notes that the sensor data indicated an object or phenomenon that could not be immediately identified by mission controllers. The filename associated with the release, “nasa-uap-d014-mercury-redstone-4-july-21-1961,” indicates that the report was generated by NASA and later transferred to the Department of Defense for review. The document is part of a broader effort by AARO to catalog and analyze historical UAP reports from military and civilian sources.
The PURSUE policy, established by the Office of the Secretary of Defense, mandates the systematic collection and evaluation of such data. The release of this 1961 report adds to a growing body of declassified materials that AARO has made public since its establishment.
The office has prioritized the digitization and release of historical records to facilitate independent analysis by researchers and the public. The report does not provide a definitive explanation for the observed phenomenon, and AARO has not yet issued a formal assessment. In the context of the Mercury-Redstone 4 mission, the spacecraft reached an altitude of approximately 190 kilometers and a speed of over 8,000 kilometers per hour.
The sensor that recorded the anomaly was part of the telemetry system designed to monitor the spacecraft’s performance and environment. The report notes that the anomaly was detected during a phase of the flight when the spacecraft was in contact with ground stations. Moving forward, AARO may request additional data from NASA archives or interview former personnel involved in the mission.
The office has the authority to conduct further analysis using modern sensor data and modeling techniques. The release of this document is part of a larger effort to ensure that historical UAP reports are available for scrutiny, with the goal of improving the understanding of such phenomena.
