During his time aboard the International Space Station Canadian astronaut Commander Chris Hadfield (@Cmdr_Hadfield) has owned social media like no astronaut before. He has been tweeting and sharing photos and creating videos that have given thousands of people a glimpse of what it is like to live and work in space.
If you haven't been looking in, you should check out his gallery of pics & videos on Twitter, Facebook or YouTube.
He returns to Earth tomorrow. His final video from his voyage is his own cover of David Bowie's Space Oddity that was shot from on board the International Space Station. It's pretty good and worth watching.
