Expedition 35 Works Science, Counts Down to Crew Change
The six-member Expedition 35 crew is working throughout the International Space Station maintaining its systems, conducting world-class science and exercising to counteract the effects of microgravity. The residents are also counting down to the departure of three members marking the beginning of Expedition 36 followed two weeks later by the arrival of three new members.
Commander Chris Hadfield started his morning setting up sound level meters, which are basically microphones, to measure the acoustic environment inside the station. Hadfield later installed a new payload Ethernet hub updating the orbital laboratory’s local area network.
Flight Engineer Chris Cassidy worked throughout the day on an ongoing fluid physics experiment. He set up science gear and a video camera to observe liquid moving up a surface, called wetting, for the Capillary Flow Experiment-2. He also calculated his mass using a device that applies a force against a crew member and measures the resulting acceleration using Newton’s second law of motion.

Inside the Columbus laboratory module, Flight Engineer Tom Marshburn changed belts and cleaned debris inside the European Modular Cultivation System. That device provides an environment allowing the study of microbes, plants, insects and small amphibians. He also transferred data gathered from a NanoRacks experiment to a laptop computer on science rack.

The three cosmonauts and flight engineers on the Russian side of the space station continued their ongoing science and maintenance work.
Pavel Vinogradov collected condensate water samples and replaced fan screens. Alexander Misurkin monitored fluid loops and worked with the Matryoshka experiment measuring radiation exposure. Roman Romanenko audited the Russian segment’s computer network and assisted Misurkin with the Matryoshka experiment.

Marshburn, Hadfield and Romanenko continue to pack personal items for their return home May 14 inside the Soyuz TMA-07M spacecraft.
On the ground, controllers are readying the Canadarm2 and Dextre, the Special Purpose Dexterous Manipulator, for another Robotic Refueling Mission (RRM) demonstration 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.

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.
