The Expedition 28 crew members living and working aboard the International Space Station focused on a variety of science experiments and maintenance duties Friday as they orbited the Earth at an altitude of 240 statute miles.

Commander Andrey Borisenko worked with the Coulomb Crystal experiment, which studies dynamic and structural characteristics of the Coulomb systems formed by charged dispersed diamagnetic macroparticles in a magnetic trap. Coulomb systems are structures following Coulomb’s Law, a law of physics describing the electrostatic interaction between electrically charged particles.

Flight Engineer Sergei Volkov set up and used video and photography equipment in support of the URAGAN experiment. URAGAN is a long-term Russian experiment that documents the changes that occur on Earth after catastrophes such as hurricanes and man-made disasters.

Borisenko and Volkov also worked with the BAR experiment, which studies leak and depressurization detection techniques on the station.

Flight Engineer Alexander Samokutyaev worked in the Russian segment of the station performing maintenance activities, including using microbial growth wipes and Fungistat disinfectant to clean areas behind wall panels which have shown some microbial contamination.

Flight Engineer Mike Fossum replaced parts and recentered the track on the Combined Operational Load Bearing External Resistance Treadmill, or COLBERT, one of the station’s treadmills. COLBERT is an integral part of the exercise equipment aboard the orbital outpost.

Flight Engineer Ron Garan located and fixed a short in the rack for the Inter-Orbit Communications System in the Kibo laboratory. He also replaced a hose and filter on the urine receptacle device associated with the Waste and Hygiene Compartment.

Flight Engineer Satoshi Furukawa focused on cargo transfers, preparing the ISS Progress 43 cargo craft for undocking later this month. He also collected biological samples, placing them in the Minus Eighty-Degree Laboratory Freezer for ISS in the Destiny laboratory.

Over the weekend, crew members will continue their daily physical exercise routines, enjoy some off-duty time, continue regular maintenance duties and have an opportunity to speak with family members.
