Story
Synopsis
Mutta Nanba loses his job after a workplace conflict and finds himself adrift in his thirties, a stark contrast to his younger brother Hibito, who is about to become an astronaut and walk on the moon. Spurred by an old childhood promise to reach space together, Mutta throws himself into JAXA's brutally competitive astronaut selection process, forcing him to confront years of self-doubt and stalled ambition. It is a patient, deeply researched story about pursuing a dream later in life, treating the real mechanics of astronaut training and space exploration with genuine care and detail.
