The International Space Station has a radiator leak in its power system. The outpost’s commander calls the situation serious, but not life-threatening.
The six-member crew on Thursday noticed white flakes of ammonia leaking out of the station. Ammonia runs through multiple radiator loops to cool the station’s power system. NASA said the leak is increasing from one previously leaking loop that can be bypassed if needed. NASA spokesman Bob Jacobs said engineers are working on rerouting electronics just in case the loop shuts down. The Earth-orbiting station has backup systems. (AP Photo/NASA)
