Former astronaut Col. Chris Hadfield on the language of Space exploration

Colonel Chris Hadfield is a veteran of three spaceflights. He crewed the US space shuttle twice, piloted the Russian Soyuz, helped build space station Mir and served as Commander of the International Space Station. Getting words and language right in as clear and a concise way is a matter of life and death for astronauts. Crews are traditionally made up of different nationalities and Russian is second to English on board. Chris Hadfield who flew several missions and captained the International Space Station talks about how astronauts communicate and the special language they use that he dubs NASA speak. He speaks several languages and lived in Russia for twenty years. As an author he has written several novels based on his experience in Space and as a fighter pilot the latest of which is The Defector. His books The Apollo Murders are being made into a series for TV. He tells Michael about the obligation he feels to share in words as best he can an experience that so few people have - of being in space and seeing Earth from afar.Producer: Maggie Ayre
