Episode 16
NASA's goal to send astronauts to Mars would require a three-year absence from Earth, during which communication in real time would be impossible due to the immense distance. Meet the psychologists whose job is to keep astronauts mentally stable in outer space, as they are caught between their dream of reaching new frontiers and the basic human need to stay connected to home.
