caption_attribution_description: Astronauts Jim Reilly (on robot arm) and Danny Olivas join up forces with their colleagues inside the shuttle and station to complete the delicate process of folding an older solar array as part of the third spacewalk of the STS-117 mission.
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.

The launch of STS-117 marked the 250th orbital human spaceflight.
  Atlantis delivered to the International Space Station (ISS) the second starboard truss segment (the S3/S4 Truss) 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 (EVA). These two days were inserted into the mission timeline after flight day 8. This possibility had been discussed prior to launch. Because of launch day and thus rendezvous day uncertainty the decision to extend was deferred until after launch. The repair of the gap in the Orbital Maneuvering System (OMS) thermal blanket (heat shielding) was conducted during EVA 3.
  STS-117 remains the longest mission for Atlantis because of the cancellation of landing opportunities on 21 June 2007 due to bad weather.  Atlantis landed at Edwards Air Force Base on 22 June 2007.
