Here's an awesome clip of Twitter Star and Canadian Space Agency Commander Chris Hadfield covering David Bowie's "Space Oddity" from the International Space Station.
Hadfield is coming back to Earth tomorrow.
It's worth watching the whole thing to see him jam out on the song's guitar break.
Bonus: here's a list of all the songs NASA ever played to wake up American astronauts in space. Let's just say it starts with Beethoven and ends with U2.
