WASHINGTON (AP) — 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 spokesman Rob Navias says the line will run out of ammonia coolant late Friday morning. The line chills power systems but power was rerouted and is operating normally. The crew is not in danger.
Space station Commander Chris Hadfield of Canada tweeted that the problem, while serious, was stabilized.
NASA will decide Friday evening if the spacewalk is needed on Saturday.
NASA suspects the leak might be on the far left truss of the station, but doesn’t know for sure.
If needed, U.S. astronauts Chris Cassidy and Tom Marshburn would make about a six-hour spacewalk. They have trained for this type of repair.
The space station always has enough emergency escape ships for the crew, but there are no plans to use them.
