Sorry if this has been asked a lot, I couldn't find anything by searching the site. I'm a software engineer looking for an open-source space exploration project to contribute to in my spare time. No real restrictions, I'm happy to learn new languages or theory if it's something I find interesting. 

It doesn't necessarily need to involve satellites or probes, it could be astronomy or even websites and support systems but it needs to be supporting space exploration to keep my interest.

Thanks in advance!
