Expedition 15

Expedition 15 was the 15th expedition to the International Space Station (ISS). Four crew members participated in the expedition, although for most of the expedition's duration only three were on the station at any one time. During Expedition 15, the ISS Integrated Truss Structure was expanded twice: STS-117 brought the S3/S4 truss, and STS-118 brought the S5 truss.

(*) number of spaceflights each crew member has completed, including this mission.

Flight Engineer Sunita Williams was the first Expedition 15 crew member to arrive. She participated in Expedition 14, until Expedition 15 Commander Fyodor Yurchikhin assumed command of the station. Williams arrived at the station on December 11, 2006, aboard the Space Shuttle Discovery flight STS-116. Yurchikhin and Flight Engineer Oleg Kotov arrived the station on 9 April, 2007 aboard Soyuz TMA-10.

On 26 April, 2007, NASA announced that Williams would return to Earth on STS-117, flown by Space Shuttle Atlantis, instead of STS-118 as originally planned.[2] Williams was replaced by Clayton Anderson, who arrived at the station aboard Atlantis, which docked on June 10.

Expedition 15 ended officially after Expedition 16 Commander Peggy Whitson arrived at the station aboard Soyuz TMA-11, and the official change of command ceremony took place on Friday, October 19, 2007.

Mission details

On October 21, 2007, after the separation of the Soyuz TMA-10 capsule, Moscow Mission Control reported that the Soyuz had entered into a ballistic trajectory, which resulted in a landing that was Template:Km to mi short of the intended Kazakhstan landing site.[3][4] Landing occurred without incident, and by 10:55 UTC, all crew members were out of the capsule, and the vehicle was secured. The only other time a Soyuz landing has resulted in a ballistic trajectory was the landing of Soyuz TMA-1, for Expedition 6.[3]
