NASA confirmed that the International Space Station has experienced a cooling system mechanical failure, according to a Dec, 12 report in CNN. NASA states that the cooling loop shut down after reaching a temperature limit. Teams with NASA and the astronauts currently in the space station are working to get the cooling loop working again. Experts are theorizing a valve may have malfunctioned and caused the growing crisis with the astronauts.

NASA says the crew and the International Space Station itself was and is in no danger.

NASA stated on Thursday that a spacewalk has not been decided on being necessary, but have not ruled out the possibility of such an operation performed by the onboard astronauts. Kenny Todd, the International Space Station mission management team chairman, stated that it could be a few days before a decision is made.

The cooling loop controls ammonia circulation around the station, keeping it a safe cool temperature.

All non-critical systems on the ISS have been shut down, but life support is running, ensuring the safety of the international crew on board.

There are two Americans on the ISS, Mike Hopkins and Rick Mastracchio; three Russians, Oleg Kotov, Sergey Ryazanskiy and Mikhail Tyurin; and one crewmember from Japan, Koichi Wakata.
