One night in 2006, when they were young, the two brothers Mutta (born 1993) and Hibito (born 1996) saw what appeared to be a UFO heading for the moon. They decided that night to both become astronauts and travel out into space.

In 2025, Hibito has become an astronaut, and he's going to go to the moon. Mutta ended up following a more traditional career path with an auto development company. However, Mutta just ruined his career through a violent altercation with his boss. Now, not only has he lost his job, he appears to be blacklisted in the entire industry. Maybe this is a rare opportunity for Mutta to once again chase his childhood dream and become an astronaut like his little brother!

won the 56th Shogakukan Manga Award and 35th Kodansha Manga Award in the General Category.

A story of space

Not a lot has been done as far as translations go for this story, but based on the first chapter alone, I'm excited. It seems to be a tale of brotherly rivalry using a mission to the moon as a backdrop, and from there, possibly a mission to Mars. The main character, the older brother, is fairly sympathetic for individuals who also have a younger brother that overshadows them (for instance me), so he's relatable in that aspect. There isn't much more I can say given the lack of releases, but I highly encourage people to give it a try. Hopefully the scanlators will continue working on it since it seems it'd be a shame to watch it fade away.

This one hit me by surprise. I've never heard about this till the anime came out, but oh boy, I am really hooked right now. The characters are fairly interesting, and even though this is a more "realistic" kind of story (or rather, because of that) it's quite easy to relate to them. I don't know much about space and astronauts, but this series has piqued my interest. I'd really wish there would be more groups scanlating this, or at least one, that can kick up the pace, and bring it up to date, seeing how it's already at 17 volumes.

Surprisingly Good

I first heard of this manga when the anime came out and I thought it would be another boring anime but after reading this I was wrong. The plot of course is different from any manga I read so it made me hesitant to read it but it's worth it. The manga can be cliche at times but what manga isn't like that now?

Anyways, the comedy is pretty good and I laughed at some of the jokes. I also like the reason why the two brothers wants to go to the moon

Saw a UFO go to the moon when they were kids

Overall it's surprisingly good and I read all the current chapters(Ch.53) in one day. I recommend this manga to people that wants to read a manga about people wanting to follow their dreams with a touch of comedy.

I pretty much decided to read this by default as almost of the projects by Extras were fantastic. Also it reminded me of ST&RS (bunch of unique tests to get a job). Only it turned out to be infinitely better. ST&RS is so juvenile whereas this series is mature with fantastic drama and comedy just as good.
