yesterday, on Wednesday December 11th, the International Space Station lost half of its vital cooling system, due to a partial power down of some systems.
The safety of the members crew is under control, "at no time was the crew or the station itself in any danger" announced officially +NASA . All the astronauts slept on the orbiting laboratory as scheduled.
The trouble on the international space station occurred when one of two pumps used to circulate ammonia coolant outside of the space station shut itself down after the detection of unexpected low temperatures. The shutdown cut off half of the ability of the space system to regulate temperatures for both its internal and external systems.
The engineer on the ground are working hard to troubleshoot the issue. If the showdown of the cooling system is due to a hardware problem, it may require that astronauts go outside ISS to replace or fix the pump module with a spare unit.
More news soon, so stay tuned.
