MIAMI--The six astronauts at the International Space Station are safe and are taking shelter in the Russian segment after an alarm went off on the US side of the orbiting outpost, NASA said Wednesday.
The US space agency said it could not confirm that an ammonia leak was the cause, as the Russian space agency reported earlier.
"ISS flight controllers are not sure if the alarm was triggered by a pressure spike, a faulty sensor, or a problem in a computer relay box," NASA said on Twitter.
