COMMANDER Chris Hadfield, a Canadian astronaut who has spent the last five months aboard the International Space Station, has said goodbye to life in zero-gravity with a moving version of David Bowie's Space Oddity.
The music video shows Cmdr Hadfield floating inside the space station while playing his guitar.
As he sings "Here I am sitting in a tin can far above the world," the Earth can be seen glowing outside the space station's windows.
At one point he sings "And I'm floating in a most peculiar way" while actually floating in mid-air.
It is believed to be the first music video filmed in space.
"With deference to the genius of David Bowie, here is Space Oddity, recorded on Station," he tweeted. "A last glimpse of the World."
David Bowie replied with the tweet "Hallo spaceboy".
The video was mixed with the help of the Canadian Space Agency and features modified lyrics that refer to the Soyuz capsule that will bring him back to Earth.
"Ground control to Major Tom, lock your Soyuz hatch and put your helmet on," he sings.
Cmdr Hadfield has become something of a celebrity during his time in the ISS.
Little-known before he set off, his photographs of the Earth from space and videos recorded inside the ISS have become a huge hit, earning him more than 770,000 followers on Twitter. He has taken a particular interest in Ireland, where his daughter has studied at Trinity College.
He is the first Canadian to command the space station and its six staff. His time onboard included an unexpected space walk to fix a coolant leak. On Sunday he handed over control to Russian Pavel Vinogradov. He flies back to Earth later today.
Commentators from the US to Australia have hailed him as hero, with some suggesting he will never need to buy a drink on Earth again.
