UFO sightings in outer space UFO sightings in outer space are sightings of unidentified flying objects reported by astronauts while in space that they could not explain at the time. These sightings have been claimed as evidence for alien visits by ufologists, although prosaic explanations have since been found for almost all of them. Some of the alleged sightings never occurred: science fiction writer Otto Binder perpetuated a hoax claiming Apollo 11 Commander Neil Armstrong had encountered UFOs during the Apollo mission. UFO proponents see comments by astronauts or photos processed by NASA as one of the "strongest bodies of evidence" because they are considered to be of high trustworthiness; however, NASA Assistant Administrator for Legislative Affairs, Robert F. Allnut, concluded in a 1970 letter, "after fifteen years of manned space voyages including space stations and landing on the Moon, spacemen have brought back not a shred of evidence -- verbal, photographic, or otherwise -- for the existence of extraterrestrial spacecraft, or 'UFOs'."
