A failure of the cooling system on the International Space Station forced astronauts to re-route power Sunday as NASA planned emergency spacewalks to fix the problem.

One cooling loop shut down Saturday night, triggering alarms throughout the orbiting station, which is operated by three Russian and three American astronauts.

NASA said the crew is safe, but an attempt to close the circuit breaker and restart the pump module that feeds the vital ammonia to the cooling system failed.

NASA also noted that another spacewalk by astronauts Wheelock and Caldwell Dyson to do maintenance work had already been scheduled for Thursday.
