NASA's Unexplained Files

Strange flying objects have been caught on NASA’s cameras and astronauts have reported seeing UFOs. Some can be identified; others remain a mystery. We’ll reveal NASA footage and interview the astronauts and scientists.

STS-114 Boomerang: July 26, 2005 - One of the cameras from Space Shuttle Discovery sees an object change direction own its own. We Are The Aliens: The theory of Panspermia is that life here on Earth may have originated elsewhere, by riding rocks to Earth after being knocked off other planets by asteroid strikes.

A distant planet shows evidence of an Earth-like atmosphere, while a mysterious light suggests an atmosphere on the Moon. Have we found evidence of a crashed alien ship in the asteroid belt? Why are there "blueberries" on Mars? 43 min | TV-PG | Premiered 03/18/2014 Apollo 12 Follower: Shortly after Apollo 12's launch the ship is struck by lightning, twice.

Alien Crash Site: The Dawn space probe in 2011 studies Vesta, a 4.5 million year old asteroid in the Asteroid Belt. Pictures seem to show the crash site of a triangular shaped object. Could it be a failed attempt at mining asteroids for precious metals by a race from beyond the solar system. The Gemini X Incident: A mission meant to learn how to dock with booster rockets in space turns strange when the astronauts spot flashing objects that suddenly disappear.

Skylab's Gremlins: NASA's Skylab is plagued by accidents, almost from the start of the mission. While trying to figure out why the mission has so many problems scientists see a photo of a mysterious object that leave and then returns.

Hubble Encounter: On the mission to repair the Hubble Space Telescope, the crew sees multiple objects buzz the mission as if watching their progress. Moon Glow: Surveyor 7 lands on the Moon prior to the first manned mission and photographs an unexpected glow. When an Apollo 17 astronaut reports a glow on the horizon, NASA finally attempts to understand the phenomenon.
