At 2:23pm EST, Astronauts Rick Mastracchio and Mike Hopkins successfully completed the installation of a new ammonia cooling pump on the International Space Station, completing a repair of a faulty module that had plagued the space station since December 11, 2013. Due to the faulty pump, several pieces of equipment on the station, including some scientific experiments, had to be shut down because the equipment couldn’t be properly cooled. “While doing the connection work, the duo demated ammonia fluid lines from a jumper box that enabled ammonia flow during the repair spacewalks,” NASA explained At the present time, though, there’s no indication of any issues. less
