Environmental Science expands upon the science system in Space Exploration. This mod adds a new type of catalogue and insight created using planetary core fragments. Collect core fragments and study them to produce data to make science even more efficiently than before! Never a better reason to build a megabase that spans the stars!

Tier 1 catalogues are made by studying basic core fragments and any 1 of the new essential resources.
Tier 2 catalogues are made by studying basic core fragments and any 2 of the new essential resources.
Tier 3 catalogues are made by studying all 4 of the new essential resources.
Tier 4 catalogues are made by studying vanilla resource fragments (as these will likely be later expansions)

Crunch these into insights and run simulations with the new insights to get more efficient significant data! All 5 insights together produce 6 significant data instead of 5.
