Astronauts plug ISS leak

Two astronauts on the International Space Station have completed a 5 hour spacewalk in order to fix an ammonia leak which was detected on Thursday. The leak, in part of the station's cooling system to one of its solar arrays, was detected on Thursday when the crew saw white flakes floating away from the station and was fixed by replacing a pump controller with a spare unit. Although the station and crew were not in danger power supply from the array was affected and electricity had to be rerouted from elsewhere to keep all systems operating.
