Astronaut bids farewell with Bowie cover version
He's showed us how to make sandwiches, brush his teeth and now astronaut Chris Hadfield has sent down his last space tutorial from the International Space Station.
This time it's a little sing song!
The Canadian's heading back to earth today after his 5 month mission but couldn't resist recording his own version of a famous tune by David Bowie.
He's built up a big following down on Earth since he started tweeting and making videos about life onboard the International Space Station.
Newsround will definitely miss his updates!
