Three crew members currently aboard the International Space Station are scheduled to end more than six months on the orbiting laboratory Tuesday, May 13 (U.S. time), and NASA Television will provide complete coverage of their return to Earth, from farewells to landing.
Expedition 39 Commander Koichi Wakata of the Japan Aerospace Exploration Agency, Flight Engineer Rick Mastracchio of NASA and Soyuz commander Mikhail Tyurin of the Russian Federal Space Agency (Roscosmos) will undock their Soyuz TMA-11M spacecraft from the station at 6:36 p.m. EDT. The spacecraft will land southeast of the remote town of Dzhezkazgan in Kazakhstan at 9:57 p.m. (7:57 a.m. May 14 local time in Dzhezkazgan). Their return will wrap up 188 days in space since launching from Kazakhstan Nov. 7.
Under the command of NASA astronaut Steve Swanson, Expedition 40 formally will begin aboard the station when Expedition 39 undocks. Swanson and his crewmates, Alexander Skvortsov and Oleg Artemyev of Roscosmos, will operate the station as a three-person crew for two weeks until the arrival of three new crew members. Reid Wiseman of NASA, Max Suraev of Roscosmos and Alexander Gerst of the European Space Agency are scheduled to launch from Baikonur, Kazakhstan on May 28 (U.S. time).
NASA TV coverage of Expedition 39's return to Earth will begin Monday, May 12, with the change of command ceremony in which Wakata will turn over command of station operations to Swanson. Coverage will continue Tuesday and Wednesday with Expedition 39 landing and post-landing activities.
