Many times when a friend is singing a cover version of a popular song, they will be doing it so good that someone will have to say to the vocalist, "Don't give up your day job!"

Chris Hadfield CAN lose his day job!

Commander Chris Hadfield, a Canadian astronaut who has spent the last five months aboard the International Space Station, is saying so long, to life in zero-gravity with a rendition of David Bowie's Space Oddity.

This is pretty cool. He made this music video in zero gravity! Kudos Commander Hadfield!
