That ammonia leak on the ISS just had to be fixed, and while NASA's got robot slaves in space to do some of its bidding, there are a few things real men still have to do. Fixing stuff like leaks is one of them. Two astronauts had to do an impromptu EVA, fit a new pump, and dive back in. This is what it looked like.
I'm not sure whether this is exhilarating or bloody scary. There really isn't a lot of fabric between you and the dark void of space. I guess when you've been up there for that long, though, space really doesn't worry you. Just don't let go, OK? [DailyMail]
