Experiments, Maintenance Keep Station Crew Busy

After a restful weekend, the Expedition 29 crew aboard the orbiting International Space Station began a new week working on science experiments and computer network maintenance Monday.

Commander Mike Fossum participated in the Integrated Resistance and Aerobic Training Study, known as Sprint, which involves ultrasound imagery taken of his leg during a shorter, more intense workout on the Advanced Resistive Exercise Device than station crew members normally perform. Sprint evaluates the use of high-intensity, low-volume exercise training to minimize loss of muscle, bone, and cardiovascular function in station crew members during long-duration missions. Fossum is the first to participate in this new protocol.

Fossum changed out batteries and performed a test with the Binary Colloidal Alloy Test-5 science payload. In this experiment, also known as BCAT-5, station crew members photograph samples of polymer and colloidal particles as they change from liquids to gases, to model that phase change. The results will help scientists develop fundamental physics concepts previously cloaked by the effects of gravity.

Flight Engineer Sergei Volkov worked with the Russian behavioral assessment TYPOLOGY, which measures a crew member’s psychophysical state and ability to withstand stress, to perform and to communicate. An EEG measures and records the electrical activity of the brain while the cosmonaut plays video games designed for the experiment.

He also watered and took photos of the plants in the Russian Plants-2 experiment, which researches plant growth and development under spaceflight conditions in a special greenhouse facility.

Additionally, Volkov stowed items for disposal in the docked Progress 42 supply ship.

Flight Engineer Satoshi Furukawa replaced the integrated router for the station’s computer network, reloaded software on some of the orbital complex’s payload computers and returned those computers to their proper locations.

Furukawa spoke with students in Kuala Lumpur, Malaysia, via Amateur Radio as part of the Malaysian Prime Minister’s National Space Challenge Trophy 2011 event.
