The Expedition 32 crew members had a light-duty work day aboard the International Space Station Thursday following a successful spacewalk performed by Flight Engineers Suni Williams and Aki Hoshide on Wednesday.

During that 6-hour, 28-minute spacewalk, Williams and Hoshide completed the installation of a Main Bus Switching Unit after cleaning and lubricating the power relay unit’s bolts and posts. The installation was hampered last week by a possible misalignment and damaged threads on the unit’s bolts and posts. They also completed the installation of a camera on the station’s robotic arm, Canadarm2.

Following their successful excursion, Williams and Hoshide performed a variety of post-spacewalk duties Thursday including cleaning their spacesuits to prepare them for long-term stowage and stowing equipment used during the spacewalk.

Williams and Hoshide also were joined by Flight Engineer Joe Acaba to participate in a post-spacewalk debriefing with ground controllers.

Working in the U.S. Destiny laboratory, Acaba removed the Secondary Power Distribution Assembly Jumper and removed and replaced the failed Remote Power Control Module. He also performed some maintenance on the station’s Water Recovery System, which supplies the crew with clean, recycled water.

Commander Gennady Padalka and Flight Engineers Sergei Revin and Yuri Malenchenko worked in the Russian segment of the station, performing a variety of routine maintenance duties and science experiments.

Revin worked with the Russian Bar experiment, which looks at methods and instruments for detecting the location of a loss of pressure aboard the station.

Padalka and Revin had some time set aside to prepare for their upcoming departure from the station. Padalka, Revin and Acaba, who arrived aboard the station in May, are set to undock in their Soyuz TMA-04M spacecraft and return to Earth on Sept. 16.
