NASA is awesome and so are their astronauts and here is even more proof, as if you needed any more. This is Commander Chris Hadfield on board the International Space Station singing a version of, what else, "Space Oddity" by David Bowie.

But only after you start your Monday with the above video.
UPDATE: Bowie approves.
