Chris Hadfield was nine years old when Neil Armstrong first walked on the moon, and after that, space travel became the young Canadian's life mission.

Decades later, Hadfield is now living aboard the International Space Station as the spacecraft's first-ever Canadian commander.

One of Hadfield's goals in his role is to inspire and instill wonder in today's children by sharing his out-of-this-world experience through online tweets, photographs and live chats with elementary school students.

Hadfield talks to CBC's Peter Mansbridge from the International Space Station.
