An astronaut has said goodbye to life on the International Space Station by making a cover version of David Bowie's Space Oddity.
But the music video could prove to be his most popular contribution yet.
The Canadian, who will fly home today as his five-month mission comes to an end, is shown playing an acoustic guitar and singing Bowie's classic Space Oddity.
The astronaut wrote on Twitter: "With deference to the genius of David Bowie, here's Space Oddity, recorded on Station. A last glimpse of the World."
Bowie replied: "Hallo Spaceboy."
Before going into orbit, Cmdr Hadfield said playing music was important in taking care of the "psychological side" of living in space.
In February he sent a message from space to veteran wildlife broadcaster Sir David Attenborough.
The astronaut asked: ''If you had an evening to spend here on the space station, how would you spend it?''
Sir David replied: ''I'd just sit and watch the Earth go by - it's a perspective I've never had.''
