The top graduate of the U.S. Air Force test pilot school in 1988 and U.S. Navy test pilot of the year in 1991, Hadfield was selected to be an astronaut in 1992. He served as Director of NASA Operations in Star City, Russia from 2001-2003, Chief of Robotics at the Johnson Space Center in Houston from 2003-2006 and Chief of International Space Station Operations there from 2006-2008. The former President of the Association of Space Explorers (2007-2011), Hadfield is also a fully qualified flight engineer cosmonaut, is fluent in Russian, and is designated a "specialist" on all Space Station systems, meaning that he has earned the highest qualification level possible for every imaginable task onboard.
