On a fateful summer night in 2006, Mutta Nanba and his younger brother Hibito witness what they believe to be a UFO flying toward the Moon. This impressing and unusual phenomenon leads both siblings vowing to become astronauts, with Hibito aiming for the Moon and Mutta, convinced that the eldest brother has to be one step ahead, for Mars. Now an adult, life hasn't turned out how Mutta had pictured it: he is diligently working in an automotive company, whereas Hibito is on his way to be the very first Japanese man to step on the Moon. However, after losing his job, Mutta is presented with an unexpected opportunity to catch up to his younger brother when the Japanese Aerospace Exploration Agency, commonly known as JAXA, accepts his application to participate in the next astronaut selection. Despite self-doubts about his prospects, Mutta is unwilling to waste this chance of a lifetime, and thus embarks on an ambitious journey to fulfill the promise made 19 years ago.

A wonderful story of pursuing one’s dream, brotherhood, life and its many obstacles, with impeccable detail in character and storytelling.


Bruh best coming to age story, Shows two amazing characters growing and showing their great abilities to become astronauts.


Consider this one a masterpiece if it were a lil shorter. Handled serious and realistic topics that r usually unseen in this form of media


Sometimes when life’s feeling groggy, I put this show on and I instantly forget it all. This show is hilarious, heart warming and just great


Plus qu’une histoire spatiale vraisemblable, une histoire touchante d’adultes réalisant leurs rêves malgré les difficultés du quotidien.

Comrade Roe

Pretty good. MC straddles an awkward line between uncomfortable and relatable, but pulls it off. Ends on an awkward note but still worth it.


Great SOL show, especially if you are a space nerd like I am.
