The six-member Expedition 35 crew is working numerous science experiments studying the effects of microgravity on life, materials and combustion. The crew is also working to maintain the systems that keep the space station in orbit and in service. Outside the station, ground controllers are conducting fine-tuned robotics tests.

Flight Engineers Chris Cassidy and Tom Marshburn partnered together in the morning for the Integrated Cardiovascular experiment performing echocardiograms using an Ultrasound 2 probe. The study observes and seeks to understand the shrinkage of the heart, or cardiac atrophy, which occurs during long duration missions in space.

Cassidy continued more work in the Microgravity Science Glovebox performing combustion science for the Burning and Suppression of Solids experiment. He then worked in the Quest airlock dumping and filling the feedwater tanks on the U.S. spacesuits for their periodic maintenance.

Marshburn continued more Ultrasound work for the Vessel Imaging study scanning his blood vessels measuring changes in thickness and pressure. He then worked various maintenance tasks and conducted a ham radio pass with students from Greensboro, N.C.

Commander Chris Hadfield photographed samples captured from the Binary Colloidal Alloy Test then loaded software on a new laptop computer for the Materials Science Research Rack. He later replaced a laptop computer for the Space Acceleration Measurement System then transferred potable for the Water Recovery System.

In the Russian segment of the station, the three cosmonauts and flight engineers worked ongoing science experiments, maintenance and cargo transfers.

Pavel Vinogradov joined Alexander Misurkin during the morning for the Sprut experiment which observes a cosmonaut’s hydration status in conjunction with microgravity. The duo later worked on cargo transfers from the newly-arrived ISS Progress 51 resupply craft and updating the station’s inventory management system.

On the ground, controllers are operating the Canadarm2 and Dextre, the Special Purpose Dexterous Manipulator, for more Robotic Refueling Mission (RRM) demonstrations on the International Space Station. The RRM uses fine-tuned robotics to test the concept that satellites never meant to be serviced can be fueled and fixed in space.

Marshburn, Hadfield and Roman Romanenko continue to pack personal items for their return home May 14 inside the Soyuz TMA-07M spacecraft.

In Star City, Russia, three new station crew members are getting ready for their May 28 mission to replace the out-going Expedition 35 trio. Flight Engineers Fyodor Yurchikhin, Karen Nyberg and Luca Parmitano will launch aboard the Soyuz TMA-09M spacecraft and dock about six hours later to the Rassvet module.
