Ammonia Leak Alarm on the ISS Forces Evacuation of US Side, Crew Safe

BabelBuilder writes: A possible ammonia leak aboard the ISS this morning caused the crew to evacuate the US side of the station. All crew aboard the station is safe. According to Universe Today, "NASA says that an alarm sounded in the US segment at about 4 a.m. EST. indicating a possible ammonia leak. As a result, all six Expedition 42 astronauts and cosmonauts evacuated the US segment." NASA thinks the alarm triggered by the ammonia leak might be a false alarm, but is going over their data.
