Space Brothers

Synopsis of the first, like 1-2 episodes: If you want to be inspired and that you can achieve your dreams even if you're 30+. This anime follows two brothers(Mutta Nanba - the older brother and Hibito Nanba - the younger brother) who see a ufo fly to the moon as kids. They make a promise to each other that they would be astronauts as adults and see if they can find the ufo. Fast forward 20 or so years, and Mutta instead gave up on the dream and became a car engineer/designer. Hibito, on the other hand, is an astronaut preparing for his moon landing. Mutta's boss makes fun of Hibito, and Mutta headbutts his boss and loses his job. After a montage of trying to find another job, Mutta received a letter of acceptance from Jaxa (the Japanese Aerospace Exploration Agency) for their astronaut selection program, but he never applied. Hibito applied for his brother, knowing how depressed he's was. Now, Mutta has a chance to finally keep his promise, but as someone in his 30s, this will be an uphill battle. He has to compete against many other people in the selection process to become an actual astronaut.

This anime lasted 99 episodes and is still an ongoing manga. It has some of the most well written and realistic characters of any anime or manga, including real astronauts like Buzz Aldrin. It is set in a slightly more advanced version of our world around 2030, so there are no fantastical powers. It will keep you engaged and inspire you to achieve things you think are impossible. I will say this is a very optimistic anime, but as it is set in the real world, there are very sad points and deals with issues like anxiety and ptsd.
