The crew of the International Space Station had to evacuate the U.S. section after an alarm was triggered around 3 a.m. CT.
U.S. crew members donned safety masks, sealed their section of the station, and moved to the Russian side. The crew is safe and in good shape, NASA said at a news conference.
Again, the #ISS crew is safe inside the Russian segment after an alarm indicated a coolant pressure spike. No ammonia leak confirmed.
NASA said that while the alarm could have been cause by an ammonia leak, there is no data to suggest that yet, and it was likely a faulty sensor or computer relay that caused it.
Update: #Exp42 crew informed by controllers that it's starting to look like a false indication, either a faulty sensor or computer relay.
