Canada's most famous astronaut Cmdr. Chris Hadfield speaks with Edmonton AM host Mark Connolly on walking, sightseeing and dreaming in space.
Hadfield is promoting his new book "An Astronaut's Guide to Life on Earth."
He told Connolly he never really intended to be an author, saying he just wanted to write a book that is useful.
Hadfield spent five months on the International Space Station earlier this year and was the first Canadian to command it.
During his stay, he garnered more than one million Twitter followers and captured the imagination of people around the globe with his often-poetic online updates, breathtaking photography, educational question-and-answer sessions and fun musical performances.
