This is a list (incomplete) of alleged sightings of unidentified flying objects or UFOs in outer space.

1991

STS-48 incident
  • Video taken during mission STS-48 of Space Shuttle Discovery while in orbit on September 15, 1991 shows a flash of light and several objects that appear to be flying in an artificial or controlled fashion. NASA explained the objects as ice particles reacting to engine jets. Philip C. Plait discussed the issue in his book Bad Astronomy, agreeing with NASA. Dr. Jack Kasher analyzed the movement of the objects, and found five proofs that the footage could not depict ice particles. Lan Fleming analyzed the flash of light that preceded the abrupt change in the course of the objects, and concluded that the exhaust plume from one of the shuttle's reaction control system rockets could not have produced the flash of light. Mark Carlotto came to the conclusion that relatively brief firings of shuttle thruster rockets acting on nearby debris particles could not explain the prolonged periods of acceleration indicated by the curved paths of the unidentified objects.

2001

STS-102 The Washington Sequence
  • Video broadcast during mission STS-102 of Space Shuttle Discovery while in orbit allegedly recorded on March 19, 2001 by Jeff Challender shows a flash of light and three objects which performed movements which included starting, stopping, accelerating, and making sudden angled turns. Lan Fleming compared the timing of the flash of light and a course change of one of the objects to the timing of shuttle thruster firings and concluded that the flash and the movement of the object could not have been caused by thruster firings.
