NASA astronauts have finished a spacewalk mission at the International Space Station. One of them, Sunita Williams has set a new world record among women, after having spent 22 hours and 37 minutes in outer space.
Their main goal was to connect a second pair of cooling lines to the station. Michael Lopez-Alegria and Sunita Williams, also photographed a solar panel, that's due to be folded up in March. The astronauts didn't have enough time to finish attaching a new cable that will allow specially equipped shuttles to tap into the station's electrical system. The team plans to finish this mission on Thursday, during their third spacewalk in nine days.
