Becoming an astronaut always seems like the ultimate unattainable dream job, but just what does it take to get one of the most exciting jobs in the world? Ireland's favourite astronaut Chris Hadfield, medical researcher Dr Kevin Fong and psychologist Dr Iya Whiteley judge a group of 12 people as they compete against each other through six weeks of astronaut training, with the winner receiving support in pursuing a career with a space agency. Contenders can be eliminated from the show at any time, with the first episode seeing them learning how to hover a helicopter.
