British astronaut Tim Peake, who is set to go into space next year, has said that learning how to live and work in space will be essential to the survival of humans.
Peake is due to spend six months on the International Space Station next year.
Major Peake is currently undergoing intensive training in Germany to prepare for the mission.
He will travel on a Soyuz rocket from Baikonur Cosmodrome in Kazakhstan and could eat a meal chosen by the public.
He told BBC News that humanity's aim is to explore the Solar System, not just for the sake of exploration, and genuinely believes it is for the sake of our own survival in the future.
Peake is currently undergoing intensive training at the European Astronaut Centre in Cologne.
