Here's our friend Commander Chris Hadfield with his tribute to David Bowie from space.
His tweets and videos from space have struck a chord with many people and now Commander Hadfield is preparing for his journey back to earth from the International Space Station.
The Canadian astronaut, who will land in Kazakhstan today, bid farewell to his followers last night with a video tribute to David Bowie's "Space Oddity".
His son Evan Hadfield, who lives in Germany, said he's not too worried about his dad's journey home.
Evan said: "I am more worried about the Bowie video, to be honest."
Bowie himself seemed to be impressed.
