Ask HN: Hobby “space” projects for developers? Or something like that?

Hello, I have a Master in Computer Science and I almost 15 years of experience working in the private sector, developing API, architectures designs, in large companies, startups, etc. I am currently working as a "CTO" (between quotes) in a new startup, defining scopes, architectures, doing dev work, also devops, etc.

However, I noticed I enjoy everything space related: books, films, tv shows. And I thought it would be nice to work on a place like that (although the dream is to work a place like NASA, I know it is impossible). Anyway, I wonder if there are any amateur projects to do as a hobbyst, space related. I dont know if you can rent a satelite and do stuff (a là DigitalOcean), or something like that.

Does anyone has any resource on how to start doing some projects that could land in a career in space-related?

Thanks!
