The most popular music video in the world right now is a recording of a forty year-old song by a man who isn’t a professional musician. However, Chris Hadfield’s version of David Bowie’s “Space Oddity” was important for a different reason: it’s the first music video to be shot entirely in space.

Hadfield, a Canadian astronaut and amateur musician, has been recording music off and on during his five-month stay on the International Space Station. In commemoration of the end of his mission in orbit, Hadfield made history with his sincere and surprisingly beautiful rendition of Bowie’s spacey classic, albeit with a few adjusted lyrics to fit in with his own return voyage.
