STS-117 (ISS assembly flight 13A) was a Space Shuttle mission flown by Space Shuttle Atlantis, launched from pad 39A of the Kennedy Space Center on 8 June 2007. Atlantis lifted off from the launch pad at 19:38 EDT. Damage from a hail storm on 26 February 2007 had previously caused the launch to be postponed from an originally-planned launch date of 15 March 2007. The launch of STS-117 marked the 250th orbital human spaceflight.
