The Expedition 32 crew members living and working aboard the International Space Station Monday continued preparations for an upcoming spacewalk and worked with a variety of science and health experiments from around the world.

Commander Gennady Padalka and Flight Engineer Yuri Malenchenko gathered equipment and completed some initial preparation work on their Russian Orlan spacesuits for a spacewalk they will conduct on Aug. 20 to prepare the Pirs docking compartment for its upcoming undocking and disposal. During the spacewalk, the cosmonauts will relocate the Strela-2 hand-operated crane from Pirs to the Zarya module. They also are scheduled to deploy a small satellite, retrieve exposure experiments and install some micrometeoroid debris shields on the exterior of the Russian segment.

Flight Engineer Joe Acaba deployed and loaded software on a laptop computer for EXPRESS Rack 7 and performed some maintenance on the Total Organic Carbon Analyzer which is necessary for checking drinking water quality aboard the orbital complex.

Flight Engineer Aki Hoshide replaced a hard drive in the Multi-purpose Small Payload Rack Laptop and gathered trash for stowage and disposal in the European Space Agency’s Automated Transfer Vehicle-3 cargo craft.

Flight Engineer Suni Williams performed some maintenance in the Columbus laboratory, replacing the air interface in the Kubik drawer.

Acaba, Hoshide and Williams also were involved in a number of health experiments throughout the day, including the Sprint experiment. Sprint involves taking ground-directed self-scans of the leg to measure the effectiveness of high-intensity, low-volume exercise training in minimizing the loss of muscle mass and bone density that occurs during long-term exposure to weightlessness.

Flight Engineer Sergei Revin worked in the Russian segment of the station, performing a variety of routine maintenance duties and monitoring its life-support systems. He also worked with the Russian Bar experiment, which looks at methods and instruments for detecting the location of a loss of pressure aboard the station.
