Expedition 26 Commander Scott Kelly performed annual maintenance on the Combined Operational Load Bearing External Resistance Treadmill (COLBERT) in the International Space Station’s Tranquility module Monday.

Kelly also participated in an experiment that tests whether drugs known as biophosphonates could serve as an additional countermeasure to fend off bone density loss in long-term space travelers.

Flight Engineer Alexander Kaleri updated virus protection software on the station’s laptop computers.

Additionally, Kaleri joined fellow Flight Engineer Oleg Skripochka in replacing smoke detectors in the Russian segment of the orbital complex.

Expedition 25 Commander Doug Wheelock and Flight Engineers Shannon Walker and Fyodor Yurchikhin safely landed their Soyuz spacecraft on the Kazakhstan steppe Thursday, wrapping up a five-month stay aboard the International Space Station.

Russian cosmonaut Yurchikhin, the Soyuz commander, was at the controls of the spacecraft as it undocked at 8:23 p.m. EST from the station’s Rassvet module. The trio landed at 11:46 p.m. (10:46 a.m. on Nov. 26 local time) at a site northeast of the town of Arkalyk.

Expedition 26 officially began with the undocking of Expedition 25’s Soyuz.

Russian cosmonaut Dmitry Kondratyev, European Space Agency astronaut Paolo Nespoli and NASA astronaut Catherine Coleman are slated to launch aboard the Soyuz TMA-20 spacecraft from the Baikonur Cosmodrome in Kazakhstan on Dec. 15, 2010. They will join the Expedition 26 crew as flight engineers on Dec. 17.
