Space Brothers is a ground-breaking anime, or Japanese animation, series about two brothers who have the same dreams, but go about achieving them in very different ways. Hibito and Mutta Nanba have always dreamed of becoming astronauts and traveling into space. Hibito, the younger brother, spends his high school and college years working towards this goal and actually ends up training to become an astronaut.

Mutta is convinced that his dream of becoming an astronaut is impossible. For this reason, he follows a much more mundane career path. His life seems to be set until he messes up at his job. He actually makes such a large mistake that he is fired, and no one in that field will hire him again. Depressed and unsure of what to do next, Mutta moves back in with his parents and begins to take small, infrequent jobs in order to earn money.

Mutta's family can't stand to see him in such a slump. Hibito is especially concerned for his older brother. He calls Mutta and reminds him that Mutta once promised to become an astronaut. With a great deal of help from his family, Mutta tweaks his resume and Hibito ensures that the resume ends up in front of the right people. Soon Mutta is on his way toward becoming an astronaut and achieving his dreams.

Mutta's career choice is not an easy one. There are many intelligent, highly qualified applicants for the astronaut program. Knowing that he has failed in a career once before, Mutta is not always certain that he can come out on top. However, despite the lack of faith he often has in himself, Mutta never gives up hope. He promises himself, his brother and his family that he will try as hard as he can so that he can, literally, reach the stars.
