Referred to as “the most famous astronaut since Neil Armstrong,” Colonel Hadfield was selected as a NASA Mission Specialist, and three years later he was aboard the Shuttle Atlantis, where he helped build the Mir space station. In 2001, on Shuttle Endeavour, Colonel Hadfield performed two spacewalks and in 2013, he became Commander of the International Space Station for six months off the planet. I caught up with Commander Hadfield to discuss his leadership learnings from an incredible career in space.
