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.

At first glance Space Brothers seems to be an anime about two brothers that just go space and do astronaut things, but oh ho, dear reader, it is so much more than that. It is a realistic journey delving into one of the most difficult professions ever conceived by man. Now that the series has concluded [for the time being], a proper review is in order.

This show is a hidden gem. Having always avoided shows with lengthy and seemingly boring settings, I found some extra time on my hands during the summer break. So I decided to use it and pick up the first few episodes of Space Brothers without expecting much. I was immediately proven wrong, thinking again and again that you should truly “never judge a book by its cover”. (I try not to but it still happens. I can’t help it when there are too many choices ¯\_(ツ)_/¯)

My first thought after reading the synopsis was why the hell are 99 episodes dedicated to these random siblings trying ...
