The six space travelers aboard the orbiting International Space Station kicked off a new week Monday, focusing on science experiments, maintenance and post-spacewalk activities.

Flight Engineer Ron Garan prepared for a new series of runs with the Synchronized Position, Hold, Engage and Reorient Experimental Satellites, or SPHERES, experiment in the Kibo laboratory. SPHERES uses three bowling-ball-sized satellites to test techniques that could lead to advancements in automated dockings, satellite servicing, spacecraft assembly and emergency repairs.

Mike Fossum, also a flight engineer, performed a session with the Shear History Extensional Rheology Experiment. Known as SHERE, the experiment is designed to investigate the effect of rotation on the stress and strain response of a polymer fluid being stretched in microgravity. SHERE provides information that is critical for the evolution of containerless processing, an important operation for fabrication of parts used on future exploration missions. This knowledge can be applied to controlling and improving Earth-based manufacturing processes as well.

Commander Andrey Borisenko worked with the radiation payload suite Matryoshka-R. The Russian payload is designed for sophisticated radiation studies and is named after the traditional Russian set of nested dolls.

Borisenko also conducted leak checks of the hatch to the ISS Progress 42 cargo craft before it was reopened following last week’s spacewalk by Flight Engineers Sergei Volkov and Alexander Samokutyaev.

Samokutyaev then stowed a Kurs antenna aboard the Progress for disposal. The antenna was removed from the interface of the Poisk and Zvezda modules during the spacewalk.

Volkov and Samokutyaev also did some post-spacewalk cleanup.

The Russian toilet aboard Zvezda shut down over the weekend due to a separator unit issue that is currently being worked. The issue needs to be resolved prior to next week, when the Waste and Hygiene Compartment will be shut down for three days of maintenance.
