Chris Hadfield has made three trips to space, observed Earth from afar, spacewalked, flown fighter jets, made music and become a novelist. Here he explores ideas he hasn't articulated before and takes us into parts of the universe most of us will never experience for ourselves. Hadfield introduces his latest book, Final Orbit, explains how he became an astronaut, thrillingly reveals what our planet looks like from space, describes what it's like heading towards the moon in a rocket, talks about the precariousness of spacewalks, reflects on what space travel has taught him about himself and humanity, and spells out his attitude to risk.
