Watch: Bowie's 'Space Oddity' space!

Commander Chris Hadfield's video dispatches from the International Space Station have captured the hearts of space nerds (and regular people) worldwide, as he's explained how even basic tasks like dental care function without gravity. But it's his most recent video, where the Canadian musician and explorer performed a classic hit by David Bowie, that has drawn attention to his array of talents and generally friendly nature.

Fair warning: this video is kind of a tear-jerker, so you may want to ensure you're in a place where a little eye-water is appropriate.
