PMA3 Relocate ops

ISS020-E-028611 (7 Aug. 2009) --- European Space Agency astronaut Frank De Winne (foreground) and Canadian Space Agency astronaut Robert Thirsk, both Expedition 20 flight engineers, work the controls of the Space Station Remote Manipulator System (SSRMS) and the Centerline Berthing Camera System (CBCS) in the International Space Station’s Destiny laboratory to relocate the Pressurized Mating Adapter 3 (PMA-3) from the Unity node nadir port to Unity’s port side. This relocation is required to allow reconfigurations on the side of the Unity node port bulkhead by the crew in a pressurized environment where PMA-3 is now located. Once these reconfigurations are completed, PMA-3 will be relocated back to Unity’s nadir port, after which the Tranquility node will be brought up and berthed to Unity’s port side on mission STS-130/20A.
