At the conclusion of his stint as commander of the International Space Station, Canadian astronaut Chris Hadfield signs off with a slick and fitting send-off prior to taking the somewhat hazardous return trip in the Soyuz capsule. Hadfield made a point in this tour of bringing the ISS mission to folks on the ground through link-ups and sing-a-longs with schools, video and photo presentations, and the general esprit de corps that says science, even space science, doesn’t have be all technical and devoid of humanity. The video is, of course, a slightly updated(!) cover of David Bowie’s well-known Space Oddity.
