 If you liked Uchuu Kyoudai |  ...then you might like Shiori Experience: Jimi na Watashi to Hen na Ojisan |
"It's never too late to chase your dreams" Both of these stories encompass this very theme, despite looking and feeling vastly different from each other. Both are also enjoyable, feel-good seinen mangas with just a teeny-bit of romance sprinkled through out the story. Though Space Brothers is more grounded in reality, while Shiori Experience is more supernatural and wacky in nature; these two give off the same vibes. If you like to read to get inspired, then I highly implore you to read Shiori Experience as well. Shiori Experience also has Kurt Cobain and Jimi Hendrix in it, so...
