Station Oxygen Generator Breaks

Astronauts on board the International Space Station are working to repair a malfunctioning oxygen generator. The primary oxygen has been working off and on over the past few days, so the crew has switched to their backup solid-fuel canisters to keep the atmosphere breathable. NASA doesn't feel that there's any urgency to the situation, and hopes to have the problem fixed shortly. Even if they don't get it working quickly, the space shuttle

Endeavour

will launch on May 30 with additional oxygen supplies.
