Lots of open-source initiatives going on in the (small) satellite world at the moment. We're hopefully going to be releasing an online platform for preliminary design and trade-off analysis in the next few months. I know of a few other companies that are working on open-sourcing different parts of the technology stack. Predicting New Space to look quite different in another 5 years, with hopefully next to no barriers to entry.

Do you have any examples of open source initiatives you are excited about?

I used to work in small sat. Two open source projects that were exciting to me when in the industry: http://cosmosrb.com/ https://cfs.gsfc.nasa.gov/

Great links

I founded an open-source library for orbital mechanics during my PhD, which is still going strong: https://github.com/tudat

We're developing a new set of modular libraries based off of Tudat: https://github.com/openastro. We're also building an open search engine for satellite subsystems: https://satsearch.co.

Some other interesting open-source stuff going on:
