context_page_description: STS-117 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.
  Atlantis delivered to the International Space Station the second starboard truss segment and its associated energy systems, including a set of solar arrays. During the course of the mission the crew installed the new truss segment, retracted one set of solar arrays, and unfolded the new set on the starboard side of the station. STS-117 also brought Expedition 15 crewmember Clayton Anderson to the station, and returned with ISS crewmember Sunita Williams.
  On 11 June 2007, NASA mission managers announced a two-day extension of the mission, adding a fourth extra-vehicular activity. These two days were inserted into the mission timeline after flight day 8. This possibility had been discussed prior to launch.

  Astronaut Mark Polansky was originally slated to pilot this mission, but was moved to STS-116, which he commanded. Also assigned to the flight were Joan Higginbotham and Richard Mastracchio, who were moved to missions STS-116 and STS-118 respectively.
