International Space Station

Commander Jeff Williams and Flight Engineer Maxim Suraev were busy aboard the International Space Station Thursday with a variety of maintenance activities and science experiments as they await the arrival of the remainder of the Expedition 22 crew.

Williams worked in the Kibo laboratory troubleshooting the System Laptop Terminal 2. He also performed a routine scrub of the coolant loops on the spacesuits inside the Quest airlock.

Williams also collected water and surface samples from around the station for analysis as part of the SWAB (Surface Water and Air Biocharacterization) experiment. The primary goal of this experiment is to use advanced technologies to better understand the types of organisms that the crew could encounter, identify their sources and assess the potential risks.
