The Expedition 29 crew wrapped up its work week conducting inspection and plumbing work. They performed ongoing science and readied a supply ship for undocking. Meanwhile in Russia, the ISS Progress 45 resupply craft is being prepared for launch with docking planned for Nov. 2.

Commander Mike Fossum spent time on the Binary Colloidal Alloy Test experiment which observes microscopic particles, or colloids, suspended in a liquid. He photographed samples from the experiment that could lead to improved manufacturing processes and commercial products.

Fossum also performed some plumbing work on the Water Recovery System replacing a recycle tank. He drained and cleaned the recycle tank and performed a leak check.

Flight Engineer Satoshi Furukawa conducted an inspection of the Gradient Heat Furnace (GHF) inside the Kibo laboratory. The GHF is used for high quality crystal growth experiments and can reach temperatures of 1600 degrees Celsius. Furukawa also joined Fossum for Ultrasound 2 operations as part of the Integrated Cardiovascular experiment. That study measures the decrease in a crew member’s heart size during long duration microgravity missions.

Working inside the Columbus laboratory Furukawa also used the Ultrasound 2 to image his blood vessels. That experiment was conducted using the Human Research Facility in conjunction with experts on the ground.

Flight Engineer Sergei Volkov continued loading trash and discarded gear in the ISS Progress 42 vehicle. The supply ship is scheduled to undock from the Pirs docking compartment on Oct. 29. Volkov also worked with the Plasma Crystal experiment. The Russian study observes ultraviolet space radiation on particle clouds charged by photoemission.

Fossum talked to students from Carver High School in Birmingham, Ala. He answered questions about how the body adapts to microgravity, how rockets travel to space and why spacesuits are necessary during spacewalks.

Friday’s Crew Earth Observations targets included the Middle Eastern and South Asian cities of Istanbul, Turkey; Karachi, Pakistan; and Mumbai, India.
