ISS Expedition 45 – U.S. EVA-33 Snapshots

International Space Station Astronauts Kjell Lindgren and Scott Kelly completed a challenging spacewalk on Friday to reconfigure the Station's external cooling system. Battling Fluid Quick Disconnect Interfaces, the two crew members successfully reversed a series of steps taken in 2012 and configured the outermost Photovoltaic Thermal Control System on the Station's port truss to a nominal configuration, also providing the system with a re-fill of ammonia coolant.
