CAPE CANAVERAL, Fla.

In a rare scare, astronauts fled the American side of the International Space Station on Wednesday after an alarm indicated a possible toxic leak. NASA later said there was no leak of ammonia coolant, and a computer problem likely set off the false alarm.

By Wednesday afternoon, the astronauts were back in the U.S. part of the orbiting outpost.
