Commander Chris Hadfield, a Canadian astronaut who has spent the last five months aboard the International Space Station, had said goodbye to life in zero-gravity with a moving version of David Bowie's Space Oddity.
.
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 midified lyrics that refer to the Soyuz capsule that will bring him back to Earth.
