Hi,
Space Exploration is being early-tested for Factorio 2.0 compatibility and although external mods aren't really a part of that, I tried to go ahead and run this mod with K2SE and it triggered some syntax issues in the SE and K2SE code paths largely due to changes in the Factorio mod API. There's also a question about a particular line that might be a typo.
In any case, out of sheer excitement, I went ahead and submitted a PR for you on Github with my changes, so feel free to do whatever you want with that! My modded mod seems to work fine so far.
Thanks for the mod work!
