The European astronaut Paolo Nespoli went to Space for the third time last July 28th. He came back 4 months and half later becoming the first 60-year-old man in history who left for a long term mission. In the 60s, astronauts could train in centers of their own nationality, while nowadays they have to travel from one to the other, having experiences in all of them to go to the ISS. That’s why I went to the European Space Agency (Germany), Roscosmos (Star City, Russia) and NASA (Houston, USA) training centers to tell Nespoli’s story during his last year on Earth. How a man becomes an astronaut.
