Science activities took center stage aboard the International Space Station Monday as the Expedition 28 crew engaged in several experiments. The astronauts and cosmonauts on the orbiting laboratory also performed maintenance tasks and moved items stored aboard the complex.

Flight Engineer Satoshi Furukawa 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 to be used on future exploration missions. This knowledge can be applied to controlling and improving Earth-based manufacturing processes as well.

Flight Engineer Ron Garan worked 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.

Station commander Andrey Borisenko spent some time with the Russian Plants-2 experiment. Plants-2 researches the growth and development of plants under spaceflight conditions in a special greenhouse facility.

He also took photos for the Russian ocean observation program known as Seiner. The program tests the interaction procedure between the crews of the station’s Russian segment and State Fishery Committee ships during the search and development of fishing productive areas of the world’s oceans.

Furukawa and fellow Flight Engineer Mike Fossum participated in an experiment that tests whether drugs known as biophosphonates could serve as an additional countermeasure to fend off bone density loss in long-term space travelers.

Sergei Volkov, also a flight engineer, worked with the Russian experiment PNEUMOCARD, which studies how the cardiovascular system responds to spaceflight conditions. The information recorded during PNEUMOCARD can be used to predict possible physical reactions of the crew members during their return to Earth.

Flight Engineer Alexander Samokutyaev replaced a carbon dioxide filter in the Russian segment of the orbital outpost and stowed the removed unit in the ISS Progress 43 cargo ship.

Garan gathered trash that will be packed into Progress 43, and Fossum unpacked some items from the other docked Russian cargo craft, ISS Progress 42. Borisenko performed an audit of items stowed aboard the Zvezda and Zarya modules.

Progress 43 is scheduled to depart from the station on Aug. 23, making room for ISS Progress 44, which will launch from the Baikonur Cosmodrome in Kazakhstan on Aug. 24.
