There were significant obstacles along the way, not least the fact that Canada didn't have a space program. But Hadfield emphasises that he didn't hope to become an astronaut.

"'I want to' or 'I dream to,' that's not nearly enough. You have to decide to. I dream of winning an Olympic gold medal, but obviously I haven't decided to because I never really worked at it. I'm not going to win an Olympic gold medal unless they give one for laziness and procrastination."

Not that he doesn't travel. He's about to tour Australia with a new live show in which he recalls his adventures in space, answers audience questions and performs music live. In 2013 Hadfield became the friendly face of off-earth travel when his cover of David Bowie's Space Oddity – performed onboard the International Space Station – became a viral hit the world over.

The novelty of the music video doesn't reflect his serious accomplishments, however. He was the first Canadian commander of the ISS, and notched up a total of 14 hours and 50 minutes of extravehicular activity (that's spacewalking to us earthbound types). He retired in 2013 but has maintained an active role as a writer, speaker and adviser.

The young Hadfield decided to become a space traveller, but the 65-year-old today notes that he never made the achievement of that goal a measure of self-worth or success. "I thought, there's a lot of forces beyond my control. Most of them. But I'm going to work really hard on the ones I can control. If I do my part right, and I get some luck, then I will have a chance of flying in space ... I got to fly in space three times. If I hadn't flown in space, I never would have thought of myself as a failure or as somehow cheated. It just helped me make all of the little decisions on a daily basis as to what to do next. "
