Station Crew Focuses on Science

Science ramped up Monday aboard the International Space Station with a variety of experiments as the Expedition 24 crew caught up on investigation time that was lost during the weeks recovering from the July 31 failure of an ammonia pump module in the complex’s Thermal Control System.

Flight Engineers Doug Wheelock and Shannon Walker collected samples for the station’s Human Research Facility, placing them in the Minus Eighty-Degree Laboratory Freezer (MELFI). MELFI supports a wide range of life science experiments by preserving biological samples collected aboard the orbital outpost for later return and analysis on Earth.

Wheelock also replaced a hard drive in the Fluid Science Laboratory in the European Columbus laboratory module.

Flight Engineer Tracy Caldwell Dyson worked with the Fluids and Combustion Facility, installing software for the Preliminary Advanced Colloids Experiments. The series of observations, known as PACE, study the behavior of particles suspended in fluid in the space environment.

Flight Engineer Mikhail Kornienko worked with the Matryoshka-R experiment. The Russian payload is designed for sophisticated radiation studies and is named after the traditional Russian set of nested dolls.

Flight Engineer Fyodor Yurchikhin gathered and stowed unneeded equipment and trash in the ISS Progress 38 cargo craft in preparation for its undocking on August 31. The ISS Progress 39 cargo craft is set to launch to the station on September 8.

After the failure of the ammonia pump, Wheelock and Caldwell Dyson performed three spacewalks to replace it.
