New York Times: A critical coolant system on the International Space Station shut itself off on Saturday. The system is one of two that remove heat generated by the lab’s electronics. To avoid the risk of overheating, mission controllers had to turn off several electric-powered systems, including two of the station’s gyroscopic stabilizers. Fortunately, the station is equipped with a spare coolant system, which, according to a NASA statement, will be swapped in no earlier than Thursday this week.
