The U.S. section of the International Space Station had to be evacuated after an alarm indicating an ammonia leak went off, early Wednesday morning.
The U.S. astronauts had to move into the Russian segment of the station, while ground crews try to figure out what happened.

There's no hard evidence that a leak even happened in the first place. Then again, when you're floating more than 200-miles above the Earth's surface, better safe than sorry's a pretty good motto.
