Thank you, Cmdr Hadfield!

His time has come to depart the International Space Station, sadly, so to send Cmdr Chris Hadfield, the man who tweets from space, on his way, we felt it was only right to put together a bumper summary of his time up there in the sky.
Ever wondered how they cleaned up spillages in space? Or how an astronaut sleeps? Hadfield was on hand to inform and enlighten us.
