Cooling Pump Fails on Space Station

NASA is reporting a glitch with one of the two cooling pumps on the International Space Station, but it says none of the six crew members are in danger, reports CNN. The crew shut down some non-essential electrical systems as a precaution while they figure what went wrong and how to fix it. Best case, it's a software glitch and a relatively easy repair. Otherwise, a spacewalk will be necessary, reports NBC News. It will likely take days or perhaps weeks to sort it all out. "They're fine for the near future," says a NASA spokesman.
