In 2013, while rotating around the Earth, Canadian astronaut Chris Hadfield recorded a cover of David Bowie’s early career hit, Space Oddity.
It started as a little “family project”, he told Lateline — something fun to do with his son, back on Earth, while he was aboard the International Space Station.
Four years later, the music video they created and released has been viewed more than 35 million times, and Hadfield, now retired, has become one of the best-loved figures in seven decades of space exploration.
