The Expedition 30 crew members living and working aboard the International Space Station worked to maintain its systems Thursday, while flight controllers performed ground-commanded robotics activity outside the orbiting laboratory.

Commander Dan Burbank and Flight Engineer Don Pettit continued their orbital plumbing work inside the Water Processing Assembly (WPA), spending most of their day replacing the system’s catalytic reactor. The WPA supplies the crew with clean, recycled water by processing condensate, urine distillate, and Oxygen Generation Assembly by-products. The repair work is expected to take several days.

Flight Engineer Andre Kuipers performed maintenance work in the U.S. modules, inspecting and cleaning bacteria filters using the vacuum cleaner. Kuipers also was assisted by Burbank during the Integrated Cardiovascular experiment, which uses ultrasound scans to research the extent and causes of weakening of the heart during long-duration spaceflight.

Later, Burbank and Pettit discussed the progress of their mission with reporters from the CBS Radio Network during an in-flight interview.

Flight Engineers and cosmonauts Anton Shkaplerov, Anatoly Ivanishin and Oleg Kononenko worked in the Russian segment of the station, maintaining and monitoring its systems, transferring cargo and performing science experiments.

Meanwhile, flight controllers worked with the station’s Special Purpose Dexterous Manipulator, or Dextre robot, on the exterior of the orbiting laboratory as operations continue with the Robotic Refueling Mission (RRM) payload. The purpose is to demonstrate the ability of robotics to perform the complex work of refueling a satellite which includes opening and closing safety caps and valves, cutting through wires, removing insulation and transferring fuel. RRM was delivered aboard space shuttle Atlantis during STS-135 last year.
