Flight Engineer Andre Kuipers spent most of his day inspecting and cleaning a cabin fan assembly and ventilation ducts in the Columbus module. The work helps ensure good air circulation throughout the International Space Station. Proper air convection prevents pockets of stagnant air that could harm breathing, clog vents and set off alarms. Commander Dan Burbank assisted Kuipers with the inspection work.

Burbank also stowed U.S. spacewalk tools used during last week’s Russian spacewalk. The commander sorted through the array of tools checking their serial numbers for proper stowage.

Kuipers joined Burbank Wednesday morning talking to students from Newton, N.J., during an educational event. The astronauts took questions from the Tri-District Curriculum Consortium students and talked about living and working aboard the station.

Flight Engineer Don Pettit worked a good part of his day in the Kibo laboratory reconfiguring a combustion chamber inside the Multipurpose Small Payload Rack. He also worked a bit on a microgravity fluids experiment and collected urine samples for stowage and analysis later.

Flight Engineers Anton Shkaplerov and Anatoly Ivanishin removed components on the Treadmill Vibration Isolation System (TVIS) and installed them on a newly assembled treadmill. The work is part of the scheduled six-month maintenance for the TVIS.

Flight Engineer Oleg Kononenko performed coolant leak checks and checked sensors throughout the station’s Russian segment as well as other maintenance tasks. The cosmonaut also installed Automated Transfer Vehicle simulation software on a Russian laptop computer.
