Commander Pavel Vinogradov and NASA station science officer Jeff Williams landed in their Soyuz TMA 8 spacecraft about 50 miles northeast of Arkalyk. Russian recovery forces and NASA officials arrived at the site shortly after the spacecraft touched down. The Soyuz undocked from the space station at 5:53 p.m. EDT.
The crew will spend several weeks in Star City, near Moscow, for debriefing and medical examinations.
With Williams and Vinogradov was Spaceflight Participant Anousheh Ansari, who flew to the station with the Expedition 14 crew and spent eight days there. The American businesswoman went to the station under a contract with the Russian Federal Space Agency.
During their mission, which launched March 29, Vinogradov and Williams were joined by Thomas Reiter, a European Space Agency astronaut from Germany. He became the first non-Russian, non-U.S. long-duration station crew member. He will remain aboard as part of the Expedition 14 crew until December when he returns to Earth on the next space shuttle flight.
Two successful spacewalks were conducted during Expedition 13. The first was by Vinogradov and Williams in Russian spacesuits and the second by Williams and Reiter in U.S. spacesuits.
Vinogradov and Williams welcomed Space Shuttle Discovery astronauts and Reiter during the STS-121 mission to the station in July. In September Space Shuttle Atlantis' crew on the STS-115 mission brought and installed the station's integrated P3/P4 truss segments.
Expedition 14 Commander Mike Lopez-Alegria, Mikhail Tyurin and Reiter, now are on their own aboard the station after a week of handover, maintenance and some science activities. Vinogradov and Tyurin replaced a major component of the Elektron oxygen-producing device, which malfunctioned shortly after Atlantis departed.
The device was activated Sept. 16 and functioned for about three hours before shutting itself off. Further troubleshooting is planned.
