The Expedition 31 crew living and working aboard the International Space Station Thursday prepared for the upcoming departure of three of its crew members, worked with a variety of science experiments and continued the ongoing maintenance of the systems aboard the orbiting laboratory.

Commander Oleg Kononenko focused on the transfer and inventory of cargo to the docked Soyuz TMA-03M spacecraft for return to Earth. He and Flight Engineers Don Pettit and Andre Kuipers are scheduled to return to Earth aboard the spacecraft on July 1.

Pettit performed maintenance on the Fluid Physics Experiment Facility in the Kibo Laboratory, cleaning up some contamination on the front and downward mirrors and collecting samples for analysis. He also performed some routine maintenance on the Water Recovery System.

Kuipers reviewed procedures for loading software on the EXPRESS Rack 4 Rack Interface Controller and inspected the water valves in the Columbus laboratory, looking for deposits due to condensation.

Flight Engineer Joe Acaba swapped laptop computers on the EXPRESS Rack 2, performing a software update on the new laptop. He also worked with the BASS (Burning and Suppression of Solids) experiment, which examines the burning and extinction characteristics of a wide variety of fuel samples in microgravity.

Flight Engineers Gennady Padalka and Sergei Revin worked in the Russian segment of the station, monitoring its systems and performing a variety of maintenance activities. Padalka performed maintenance on the Elektron oxygen generator, while Revin performed an oxygen transfer from the docked ISS Progress 47 cargo craft.
