(NASA) – As the rest of the Expedition 22 crew prepares for its launch to the International Space Station, the crew onboard the orbiting laboratory continued its normal science and maintenance activities Monday.

Commander Jeff Williams worked with the Environmental Health System Gas Chromatograph/Differential Mobility Spectrometer, part of the station’s air quality monitoring system that demonstrates commercial off-the-shelf technology for identifying volatile organic compounds.

He also performed a routine inspection of the seals on the hatches in the U.S. segment of the orbital complex.

Flight Engineer Maxim Suraev worked on the Matryoshka-R experiment, which is designed for sophisticated studies of radiation’s effects on the human body. Named for the traditional Russian set of nested dolls, the Matryoshka suite consists of Bubble dosimeter detectors that are positioned at their exposure locations around the Russian segment of the station.

Ground controllers began upgrading software on some of the station’s computers, a process which will continue over the course of three days.

Williams and Suraev are currently the sole residents on the International Space Station. Three new crew members are preparing to join them when the Soyuz TMA-17 launches on Dec. 20 from Baikonur Cosmodrome.

An international crew comprised of NASA astronaut T.J. Creamer, Russian cosmonaut Oleg Kotov and Japan Aerospace Exploration Agency astronaut Soichi Noguchi will complete the Expedition 22 crew when they dock to the station on Dec. 22.
