On March 26, Kimbrough and Flight Engineer Thomas Pesquet, KG5FYG, of the European Space Agency, wrapped up a 6.5-hour spacewalk, during which, among other things, they successfully disconnected cables and electrical connections on the Pressurized Mating Adapter-3 in preparation for moving it robotically from the Tranquility module. The PMA-3 provides the pressurized interface between the station modules and the International Docking Adapter, which will accommodate commercial crew vehicle dockings.
International Space Station (ISS) Expedition 50 Commander Shane Kimbrough, KE5HOD, will take one more spacewalk on March 30 before he heads back to Earth in a Soyuz MS-02 vehicle on April 10, joined by crewmates Sergey Ryzhikov and Andrey Borisenko. The spacewalks are aimed at preparing the station for the future arrival of US commercial crew spacecraft and upgrading station hardware.
