Documents / Official release
This 1998 NASA file holds UFO-related letters from constituents that were forwarded by members of Congress, together with NASA's handling records. Senator Olympia Snowe forwarded letters from Maine residents, including a 12-year-old who asked for Roswell documents and listed a number of reported sightings. Senator Charles Grassley forwarded a question about astronaut UFO sightings. NASA's reply says it has no UFO program and has not withheld anything. The reply enclosed a NASA fact sheet and James Oberg's article, which explains the Gemini-4 McDivitt object as the spacecraft's own booster.
From the source:Release of 2026-06-12 Released with redactions. This collection of documents, primarily from 1998, contains draft and final correspondence from the White House and the offices of members of Congress responding to constituent inquiries about Unidentified Flying Objects, or “UFOs.” These inquiries cover a diverse range of topics, including alleged UFO sightings by NASA astronauts, questions regarding the authenticity of photos collected during U.S. missions to Mars, alleged improper withholding of information by the U.S. Government, questions regarding the appropriateness of “UFO-related” governmental spending, and calls for congressional hearings regarding the nature and existence of “UFOs.” The official responses consistently state that, circa 1998, the U.S. Government is not aware of evidence supporting the existence of extraterrestrial technology, and that NASA does not actively investigate “UFOs.” The collection includes references to materials of both confirmed and unconfirmed authenticity, as provided by constituents, as well as references to historical, scientific literature addressing specific “UFO” sighting claims.

NASA FactsNational Aeronautics and Space Administration NASA Headquarters Public Affairs Office Code P 300 E Street SW Washington DC 20546 FS-1997-01-017-HQ The US Government and Unidentified Flying Objects No branch of the United States Government is cwrently in volved with or responsible for investigations into the possi bility ofalien life on other planets or for investigating Uni dentifiedFlyingObjects (UFO's). The US Air Force (USAF) and the National Aeronautics and Space Administration (NASA) have had intennittent, independent investigations ofthe possibility ofalien life onother planets; however, none of these has produced factual evidence that life exists on other planets, nor that UFO's are related to aliens. From 1947 to 1969, the Air Force investigated UFO's; then in1977, NASA was asked to examine the possibility of resuming UFO investigations. After studying all of the facts avail able, it was determined that nothing would be gained by further investigation, since there was an absence oftangiole evidence. In October 1992, NASA was directed by Congress to begin a detailed search for artificial radio signals from other civi lizations under the NASA Towards Other Planetary Systems (TOPS)/High Resolution Microwave Swvey (HR.MS) pro gram (also known as the Search for Extraterrestrial Intelli gence project). Congress directed NASA to end this project in October 1993, citing pressures on the US Federal budget The HRMS did not detect any confmned signal before it was stopped. However, similar work will continue in a more limited manner through efforts ofprivate groups and through academic institutions. The Search for Extraterrestrial Intel ligence Institute (SETI Institute) in Mountain View, CA, effectively replaced the Government project, borrowing the signal processing system from NASA: The SETI Institute is a nonprofit corporation conducting research in a number offields including all science and technology aspects of as tronomy and planetary sciences, chemical evolution, the ori gin of life, biological evolution, and cultural evolution. During several space missions, NASA astronauts have re ported phenomena not immediately explainable; however, in every instance NASA determined that the observations could not be tenned "abnormal" in the space environment. The 1947 to 1969 USAF investigations studied UFO's un derProject Blue Book. The project, headquartered atWright Patterson Air Force Base, Ohio, was terminated December 17, 1969. Ofthe total of12,618 sightings reported to Project Blue Book, 701 remain "unidentified." The decision to discontinue UFO investigations was based on an evaluation of a report prepared by the University of Colorado entitled, "Scientific Study ofUnidentified Flying Objects;" a review ofthe University of Colorado's report by the National Academy of Sciences; previous UFO studies; and Air Force experience investigating UFO reports during the 1940's, '50's and '60's. As a result ofexperience, inves tigations, and studies since 1948, the conclusions ofProject Blue Book were: (1) no UFO reported, investigated, and evaluated by the Air Force was ever a threat to our national security; (2) there was no evidence submitted to, or discov ered by, the Air Force that sightings categorized as "uniden tified" represented technological developments orprinciples beyond the range of modem scientific knowledge; and (3) there was no evidence indicating that sightings categorized as "unidentified" were extraterrestrial vehicles. With the termination ofProject Blue Book, the USAF regu lation establishing and controlling the program for investi gating and analyzing UFO's was rescinded. Documentation regarding the former Project Blue Book investigation was permanently transferred to the Modem Military Branch, National Archives and Records Service, in Washington, DC 20408, and is available for public review and analysis. Since the termination ofProject Blue Book, nothing has oc cwred that would support a resumption of UFO investiga tions by the USAF or NASA. Given the cwrent environ ment of steadily decreasing defense and space budgets, it is unlikely that the Air Force or NASA will become involved in this type of costly project in the foreseeable future.
