The International Space Station has been forced to shut down many of its systems after a coolant leak.
NASA has confirmed the station is having problems with its coolant system due to a faulty valves. Early reports of the difficulties appeared in tweets from the station's crew and support staff.
The crew are struggling to restore pressure to the coolant system that keeps the vital systems, including life-support, at a regular temperature. This can vary wildly depending on whether the space station is in sunlight or in the Earth's shadow.
