Our journey on earth is short. Yet we all have the power to be explorers, whether its on earth or elsewhere. We can explore, without limits. It is perhaps not surprising to learn that as a youth Jeremy Hansen, who later became a CF-18 fighter pilot, turned his treehouse into a spaceship and later joined the Air Cadets. A modern-day explorer, Jeremy has lived in underground caves and undergone geological training expeditions in the High Arctic. He just generally craves adventure. A Canadian Space Agency Astronaut since 2009, LCol Hansen works as Capcom at NASA's Mission Control Center and recently guided the crew in the planning and execution of underwater Extravehicular Activities.
