Story highlights The scare was a false alarm, NASA says The U.S. astronauts are safe, NASA says <\/p>\n
A possible ammonia leak in the cooling system had the crew from the American segment of the station move temporarily to the Russian segment. <\/p>\n
It was a false alarm, NASA said. <\/p>\n
Tests indicated that the off-scale measurements were the result of a computer failure, and not an ammonia leak. <\/p>\n
International Space Station program manager Mike Suffredini said the relocation was done as a precaution because of four measurements that were off scale. These measures could have indicated an ammonia leak. <\/p>\n
The astronauts, as trained, put on masks, moved to the Russian segment, and closed the hatch to the American segment, he said. <\/p>\n
Two U.S. astronauts are aboard the International Space Station: commander Barry Wilmore and flight engineer Terry Virts. <\/p>\n
Once it was determined that the emergency was a false alarm, the astronauts still had to wait while equipment on the U.S. segment was powered back up, Suffredini said. <\/p>\n
NASA tweeted that at 3:05 p.m. ET, the hatch was reopened and the astronauts returned. There was no ammonia in the area, NASA said. <\/p>\n
The crew was unable to carry out experiments that were planned, but no research was lost, Suffredini said. <\/p>\n
