This record, designated USG-UAP-D001, is a collection of interagency and congressional correspondence from 1998 documenting constituent inquiries about Unidentified Flying Objects and related U.S. government activities. It was released as part of PURSUE Release 03 on June 12, 2026, by the U.S. Government. The correspondence involves the White House, the offices of several members of Congress, and NASA, and spans the period from approximately March through September 1998. No specific incident location is recorded; the inquiries originate from constituents across several states. 123
Provenance and Chain of Custody
The document is filed under classification code "1320.4 Aeronautics:UFO" and was maintained in the NASA Headquarters Action Tracking System (HATS). All substantive portions are marked UNCLASSIFIED/PUBLIC. Personal identifiers throughout have been redacted under (b)(6) privacy exemptions, meaning constituent names and contact details are withheld, while administrative tracking dates, routing information, and the names of government officials are preserved. The collection contains administrative tracking records, formal NASA response letters, and constituent letters forwarded through congressional offices.
The source PDF runs to approximately 86 pages. OCR extraction is incomplete: the document digest covers the full set of congressional inquiries and includes the complete text of a 1976 journal article enclosed with one response, but some constituent letters and NASA Fact Sheets referenced in the routing records are documented through image extraction rather than full OCR transcription. No classification markings indicate that any portion has been withheld for national security reasons; redactions are limited to personal identifying information.
The Five Congressional Inquiries
The collection encompasses five distinct inquiries processed between May and September 1998. Each was assigned a tracking number within the NASA HATS system.
Inquiry L11998-00407 was forwarded by Senator Olympia J. Snowe in May 1998 on behalf of a constituent from Stockington, Maine. The constituent raised questions about the authenticity of recently released Mars photographs, specifically asking whether image compression had degraded digital data from the Mars Global Surveyor (MGS). NASA responded on June 2, 1998, clarifying that no new Mariner photographs had been released; the images in question were MGS data transmitted as digital binary streams and processed by NASA into visual format. The agency noted that all MGS images are deposited in a publicly accessible archive within six months of receipt.
Inquiry L/1998-00729 was forwarded by Senator Charles E. Grassley in August 1998. A constituent had requested information about UFO sightings reported by NASA astronauts. Edward Heffernan, NASA's Associate Administrator for Legislative Affairs, responded that objects observed by astronauts over decades had, in virtually all cases, been subsequently identified through photographs or NORAD records as material from launch vehicles, spacecraft systems, or water droplets. Heffernan stated that no unidentified materials were observed during lunar missions. The response enclosed a 1976 article by James E. Oberg published in SEARCH magazine and a NASA Fact Sheet summarizing the agency's historical involvement with UFO investigations.
Inquiries L/1998-00494 and A/1998-00461 arose from a White House referral. A constituent from Minneapolis, Minnesota, who identified as a member of CSETI (the Center for the Study of Extraterrestrial Intelligence), submitted correspondence through the White House website mail form on March 16, 1998. The letter referenced an alleged December 1997 briefing of President Clinton, Vice President Gore, the CIA director, members of Congress, and Pentagon representatives by Dr. Steven Greer regarding purported extraterrestrial evidence. The constituent urged the President to order open congressional hearings on UFO existence and requested transparency regarding alleged obstruction by a group referred to as "MJ-12." NASA's response acknowledged that no congressional hearings on UFOs were scheduled and provided the standard Fact Sheet.
Inquiry U1998-00470 was forwarded by Representative Bart Gordon in June 1998. A Tennessee constituent asked whether NASA was spending taxpayer funds on searches for extraterrestrial life. NASA's response noted that Congress had directed the agency to end its High Resolution Microwave Survey (HRMS) project in 1993 due to budget constraints, and that the SETI Institute in Mountain View, California, had assumed the private continuation of that research.
Inquiry L/1998-00415 was forwarded by Senator Olympia J. Snowe in May 1998. The letter came from a 12-year-old constituent from Portland, Maine, who identified as a "U.F.O. researcher" and submitted a detailed FOIA-style request for Roswell crash documents. The letter listed 15 specific alleged sightings and abduction incidents at locations including Las Lunas, New Mexico (June 1977); Shiroyama, Kawanoe City, Japan (February 2, 1975); Waikiki Beach, Honolulu (March 15, 1993); Colfax, Wisconsin (April 19, 1978); Gulf Breeze, Florida (September 24, 1994); and Groom Lake, Nevada (no specific date). The writer referenced Hangar 18 at Wright Patterson Air Force Base, a "government agency called M.J.12," and an alleged alien landing at "Hulaman Air Force Base." NASA's response directed the constituent to standard public resources.
The Oberg Article: Systematic Analysis of Astronaut UFO Claims
A substantial portion of the collection consists of a 1976 article by James E. Oberg, Associate Editor of Space World magazine, published in SEARCH magazine (Winter 1976, Palmer Publications, Amherst, Wisconsin). NASA enclosed this article with at least one congressional response as a reference document. Oberg's analysis systematically examines the major astronaut UFO cases cited in UFO literature and assesses each against available photographic records, flight transcripts, and NORAD tracking data.
Oberg describes NASA's photographic archive distribution in four tiers, from lithographed popular prints to individual orders from Barra Studios in Bladensburg, Maryland, noting that all American space photographs are publicly accessible and indexed by standardized codes. He uses this to rebut claims of NASA photo suppression.
The Gemini-4 McDivitt Case
The centerpiece of Oberg's analysis is the June 3, 1965 sighting by Astronaut Jim McDivitt during Gemini-4. Approximately 30 hours into the four-day mission, while crewmate Ed White slept, McDivitt reported an object near the capsule that appeared to be approaching on a collision course -- a cylindrical shape with an "arm sticking out." NASA Houston contacted NORAD, which provided a list of approximately a dozen tracked objects. All were identified except the Pegasus-2 meteor satellite, which NASA publicly designated as the probable explanation.
Oberg challenges this identification through trajectory analysis. Pegasus-2 had been more than 1,000 miles distant from Gemini-4 at the relevant time -- an impossible match for McDivitt's description of a nearby object in near-collision geometry. The critical oversight: NORAD's list was incomplete because NASA had queried for Gemini-7 and earlier satellites, not for Gemini-4's own associated debris. The Gemini-4 booster itself -- a 30-foot cylinder that McDivitt had tracked visually at ranges as close as ten miles during the mission -- was not in the comparison data.
Oberg cites complete Gemini-4 flight transcripts and on-board tape recordings. McDivitt had previously spotted and misidentified the booster, noting "straps hanging from it" corresponding to actual insulation and structural elements. Flight surgeon notes document that McDivitt's eyes were irritated from cabin atmosphere issues and an accidental urine spill. McDivitt's photographic attempt through a smeared window was cut short when slow spacecraft stabilization rotation carried the object into sun glare after roughly 30 seconds. Examination of all flight films revealed no anomalous objects -- only overexposed or blank frames.
Despite this, the case became prominent in UFO literature. NICAP circulated a copy of McDivitt's photograph with a handwritten annotation of unknown origin claiming the image showed "his UFO." Following his retirement in 1969, McDivitt told national television audiences: "I have never been able to identify it, and I don't think anyone ever will" -- a statement Oberg documents as contradicting the flight record. A NASA official memo dated July 1, 1965, had stated: "We believe it to be a rocket tank or spent second stage of a rocket." NORAD's Public Information Officer D.W. Kindschi confirmed on February 23, 1976, that Oberg's analysis of the NORAD role "appear[s] to be logical."
Oberg concludes: "The 'McDivitt case' is closed; the best space UFO case has now been identified."
Other Astronaut Cases
Oberg examines additional cases. During Gemini-12, Astronauts Jim Lovell and Edwin Aldrin reported four objects in a row during post-EVA sunrise conditions; flight transcripts confirm these were materials discarded during the mission. Scott Carpenter's Mercury-7 "saucer" sighting was a tracking balloon ejected from the capsule for a practice exercise that failed to inflate. Gordon Cooper's Mercury-9 case involved a green object report accompanied by claims that a tracking station radar detected over 100 targets; Oberg treats the radar targets as nonexistent. The Gemini-11 case, in which Astronaut Charles "Pete" Conrad photographed a "morning object," is identified by Oberg as Proton-3, a Soviet satellite in a decaying orbit moving faster than NORAD's extrapolated predictions, placing it several hundred miles closer to the spacecraft than tracking data initially suggested.
Oberg also exposes a deliberate photograph hoax: a forged image depicting two hexagonal glowing objects in space, widely circulated in UFO publications, was created by retouching a genuine Gemini-7 photograph (NASA S65-63722) to remove the spacecraft nose, leaving two roll-control rocket thrusters catching sunlight appearing to float in space.
Environmental and Photographic Factors
Oberg catalogs the physical environment around spacecraft that generates spurious observations: clouds of debris from leaking fuel, dumped water, chipping paint, fraying insulation, and ejected equipment; floating particles inside weightless cabin interiors; and window distortion from sealant seepage and rocket fuel contamination. He documents collaboration with Richard Underwood, a NASA Johnson Space Center photo analyst who examined every photograph returned from orbit and reported finding no anomalous objects.
Official Government Position Across All Inquiries
NASA's responses across all five 1998 inquiries state consistently and unambiguously that no branch of the U.S. Government was then investigating UFOs or possessed evidence of extraterrestrial life or technology. The responses reference Project Blue Book (1947-1969), which investigated 12,618 reported sightings and left 701 unidentified, while producing no evidence of extraterrestrial vehicles or national security threats. The agency maintained an open photographic archive and described SETI-type research as a matter for private organizations and academic institutions.
What The Record Supports
This collection establishes that in 1998, NASA and congressional offices received a sustained stream of constituent inquiries about UFOs, astronaut sightings, Mars imagery, government secrecy, and extraterrestrial evidence, and that official responses were uniform in denying any government awareness of extraterrestrial technology. The Oberg article enclosed with at least one response provides a detailed contemporaneous analysis of major astronaut sighting cases, each of which Oberg identifies as explainable through documented space environment phenomena, incomplete NORAD tracking data, or deliberate hoax.
The record does not establish that any astronaut observed an object of extraterrestrial origin. It does not confirm the existence of MJ-12, Hangar 18 facilities at Wright Patterson Air Force Base, alien landings, or presidential briefings on extraterrestrial evidence. Constituent letters referencing these matters reflect folklore narratives circulating in UFO research communities at the time; no official document in this collection corroborates any of them.
The 701 Project Blue Book unresolved cases are noted in the official NASA responses as unidentified -- not identified as extraterrestrial. The cases examined by Oberg were, in his assessment, resolved through rigorous analysis that UFO researchers declined to publish or acknowledge.
The collection is a public record of how the U.S. government communicated with the public on UFO matters in 1998. It does not represent new disclosures of operational UAP encounters or intelligence assessments.
