Lets start this off with my biggest complaint currently, while it's theoretically nice to have an early-game space-only path towards expanding space platforms, at 15 entire oxide chunks per foundation it's pretty expensive compared to the vanilla recipe even after considering the saved iron (and smelters) from not using steel, to the point that I've found it more scalable to just ship up the wire for the base recipe from nauvis or vulcanus until i've unlocked reprocessing at the minimum, at which point I'm rarely in a position anymore where i would care enough about the slightly easier platform construction to change whatever setup I've already got going at that point.

Other than that It'd be pretty useful if you could move Synthetic coal to an alternate crushing recipe (maybe completely replacing carbon for it?), because as-is adding your mod mid run, or using blueprinted ships, tends to deadlock them with the sudden new byproduct. Also your description for catalyst says it's "mostly recovered after use", yet in the only recipe currently using it it's only returned at a mere 20% chance, you might want to either re balance or change the description on that, as it's pretty inaccurate currently
