Overview
A newly released NASA Freedom of Information Act (FOIA) file is drawing attention to the agency’s handling of Unidentified Anomalous Phenomena (UAP) records. The release, identified as FOIA case 26-00789-F-HQ, contains 3,668 pages of material—2,778 pages released in full and 890 released in part. Its publication has prompted questions about how the documents relate to earlier NASA statements that the agency did not maintain records specifically classified as UAP material.
The documents were obtained after a request filed on May 4, 2026, seeking communications between Mark McInerney, described in the request as NASA’s Director of UAP Research, and research librarians at the Goddard Space Flight Center (GSFC). NASA provided the response on September 28, 2026. According to the material, the records primarily concern efforts to locate and compile technical and scientific literature rather than a standalone archive of unexplained-observation case files.
What NASA Previously Said
The release is being compared with an earlier NASA FOIA case, 26-00029-F-HQ, in which Dr. Daniel Evans stated that “NASA currently does not hold or manage records classified specifically as UAP documents.” Evans served as the designated federal officer for NASA’s UAP Independent Study Team, which produced its final report and recommendations in 2023.
That statement was consistent with NASA’s public messaging during a September 14, 2023, media briefing. Administrator Bill Nelson and Evans emphasized transparency, scientific rigor and the need to improve the quality and availability of data related to UAP reports. NASA’s position, as reflected in the quoted correspondence, appears to have concerned the agency’s records-management categories—not necessarily whether NASA employees had ever discussed unusual aerial observations or conducted research relevant to them.
What the New Records Show
The newly released correspondence indicates that McInerney worked with GSFC library personnel during the latter half of 2023 to identify research relevant to several possible explanations for reported anomalous objects. The effort included searches involving advanced aerospace platforms, propulsion systems and perceptual phenomena.
One documented area of inquiry involved advanced airframes. In September 2023, McInerney requested academic and industry literature on state-of-the-art spherical and triangular drones. Library staff then curated material concerning spherical unmanned aerial vehicles and related technologies. The records therefore appear to show an active internal research process, even if the resulting materials were collected as general technical literature rather than labeled or stored as formal “UAP documents.”
Why the Distinction Matters
The central issue is administrative and definitional. An agency can lack records filed under a specific “UAP” designation while still possessing emails, research requests, library searches and technical publications that concern subjects relevant to UAP investigations. In that sense, the 3,668-page production may reveal a more complicated picture of NASA’s activities without necessarily proving that the agency’s earlier statement was false.
The available source material does not establish the full contents of the release, the identities of all individuals involved, or whether any pages contain evidence of specific unexplained incidents. It also does not, by itself, demonstrate that NASA maintained a dedicated UAP database or withheld a collection of classified UAP case files. The documents appear to broaden the picture of NASA’s research-related activity, but their significance depends on how “UAP records” is defined and on a complete review of the released pages.
Context and Next Questions
The disclosure nevertheless raises practical questions about NASA’s internal coordination. Researchers may seek to determine whether the literature searches led to formal studies, technical assessments or referrals to other government offices. They may also examine the partially released pages for information about exemptions, redactions and the scope of NASA’s search.
For now, the FOIA production supports a measured conclusion: NASA appears to have engaged in organized research on technologies and phenomena relevant to UAP, while maintaining that it did not manage records specifically classified as UAP documents. That distinction—not evidence of extraordinary technology or extraterrestrial activity—is the principal finding supported by the information currently available.
