Flight Engineers Sergei Volkov and Alexander Samokutyaev will exit the International Space Station Aug. 3 to conduct a spacewalk. The cosmonauts will exit the Pirs docking compartment and work to move a transport boom, install a communications terminal and remove and inspect antennas among other tasks. The Russian spacewalk is expected to last six hours.

This will be Volkov’s third spacewalk. As commander of Expedition 17 he conducted two spacewalks in July of 2008 for a total of 12 hours and 12 minutes. Samokutyaev will be conducting his first spacewalk.

The pair activated and inspected their Russian Orlan spacesuits in advance of next Wednesday’s spacewalk. The spacewalkers also checked cooling loops and interface units.

Commander Andrey Borisenko worked in the Russian segment of the station and checked cable connections and a laptop power supply. He also worked to transfer water from the ISS Progress 43 resupply vehicle to the ISS Progress 42.

Flight Engineer Ron Garan worked on the Water Recovery System. He removed and replaced a filter tank assembly. Garan delayed work scheduled for the Binary Colloidal Alloy Test experiment and instead focused on exercise.

Flight Engineer Mike Fossum rerouted a space-to-ground antenna cable in the Destiny laboratory to prevent damage from inside a rack. Fossum also swapped out a battery from the EarthKam camera. EarthKam is a student operated experiment which photographs targets on Earth.

Fossum also conducted science with the Shear History Extensional Rheology Experiment. That experiment studies polymer fluids stretched in microgravity which could provide benefits for future space missions and improved manufacturing processes on Earth.

Satoshi Furukawa, a Japan Aerospace Exploration Agency astronaut and flight engineer, set up a camcorder inside the Kibo laboratory. Furukawa also worked inside the permanent multi-purpose module to organize stowed food.

Finally, all six Expedition 28 crew members gathered together and hung a plaque in commemoration of STS-135, the last mission of the Space Shuttle Program.
