With the impending launch of the STS-128 space shuttle mission slated for early Tuesday morning, the International Space Station's Expedition 20 crew spent Monday working on its regular science and maintenance activities and preparing for the shuttle's arrival.

Commander Gennady Padalka and Flight Engineer Roman Romanenko performed some regular maintenance activities in the station's Russian segment. Padalka cleaned fan screens in the docking compartment, and Romanenko did some work on the segment's life support system.

Flight Engineer Mike Barratt worked on the Lab-on-a-Chip Application Development-Portable Test System (LOCAD-PTS) experiment. LOCAD uses small cartridges and a handheld device to detect the presence of bacteria. Later, Barratt did some maintenance work on spacesuit water tanks. He also participated in an amateur radio session with students at Tenison Woods College in Mount Gambier, South Australia.
