Hadfield, 53, an engineer and former test pilot from Milton, Ontario, was Canada's first professional astronaut to live aboard the space station and became the first Canadian in charge of a spacecraft. He relinquished command of the space station on Sunday.
"It's just been an extremely fulfilling and amazing experience end to end," Hadfield told Mission Control on Monday. "From this Canadian to all the rest of them, I offer an enormous debt of thanks." He was referring to all those in the Canadian Space Agency who helped make his flight possible.
Hadfield bowed out of orbit by posting a music video on YouTube on Sunday — his own custom version of David Bowie's "Space Oddity." It's believed to be the first music video made in space, according to NASA.
"With deference to the genius of David Bowie, here's Space Oddity, recorded on Station. A last glimpse of the World," Hadfield said via Twitter.
Hadfield sang often in orbit, using a guitar already aboard the complex, and even took part in a live, Canadian coast-to-coast concert in February that included the Barenaked Ladies' Ed Robertson and a youth choir.
The five-minute video posted Sunday drew a salute from Bowie's official Facebook page: "It's possibly the most poignant version of the song ever created."
