What happens if both U.S. cooling loops on the space station fail?
If both U.S. cooling loops fail (an unlikely event according to NASA) the space station’s U.S. systems could be powered down and the crew moved into the Russian segment for a time, NASA officials have said. Since the Russian side of the space station has an independent cooling system, it could support a six-person crew for a short while, perhaps a few days until a repair or response is made, station managers said.
