The international team accelerates its plans to launch a human mission, drawing together astronauts from Canada, the United States, Russia, France and Japan for a gruelling assignment. In a capsule the size of just two school buses, these four men and two women must work together as a team and struggle with the sacrifice of leaving friends and family behind. This elite crew - after years of training and psychological evaluations - band together for the ultimate career-making mission. This journey will last for nearly 600 days and will take them 56-million kilometres away from their lives on Earth - and the physical and psychological isolation they experience will be unlike anything these astronauts have ever known.
