Expedition 15 Commander Fyodor Yurchikhin and Flight Engineers Oleg Kotov and Clay Anderson concluded joint operations with the STS-118 crew Saturday afternoon. STS-118's stay at the station began Aug. 10 and featured four spacewalks to continue the on-orbit construction of the station.

The STS-118 crew exited the station before hatches closed at 5:10 p.m. EDT Saturday in preparation for undocking on Sunday.

In addition to the seven STS-118 astronauts, Space Shuttle Endeavour carried the Starboard 5 (S5) truss segment to the station and STS-118 spacewalkers installed it Aug. 11. The S5 truss segment is part of the station's Integrated Truss Structure that will eventually be the length of a football field and contain four sets of solar arrays.
