The Space Shuttle Atlantis was a Space Shuttle orbiter in the Space Shuttle fleet belonging to the National Aeronautics and Space Administration (NASA), the spaceflight and space exploration agency of the United States. Atlantis was the fourth operational (and the next-to-the-last) Space Shuttle to be constructed by the Rockwell International company in Southern California, and it was delivered to the John F. Kennedy Space Center in eastern Florida in April 1985.
