On January 10, 2004, the Mars Rover science team unveiled some of the first true images of Mars showing a Blue Sky at a news conference at the Jet Propulsion Laboratory in Pasadena, California. NASA's official fact sheet claims there is no evidence of alien life or UFO's and in the past has only released images of orange or red skies.
