The spacewalk outside the International Space Station was captured on film by the tweeting, Facebooking, social media maven and space station commander Chris Hadfield. "Amazing day," he said. "EVA went off without a hitch. Great crew, phenomenal ground support and a supportive audience. Who could ask for anything more?"

How 'bout a picturesque view? We've got that too! See a collection of great images from the EVA, which -- for the moment -- appears to have been a success in fixing the leaking ammonia coolant system.
