The Expedition 15 crew wrapped up a busy week of robotics and set the stage for future growth of the International Space Station with the relocation of Pressurized Mating Adapter-3 (PMA-3).

Thursday, Flight Engineer Clay Anderson used the station's robotic arm to move PMA-3 from Unity's port docking mechanism to its nadir, or earth-facing, docking mechanism to make room for the installation of the Harmony node, which is set to arrive on Space Shuttle Discovery in October.
