Based on External rocket parts by Vellanix and Diverse rockets by HunD34TH.

new rocket recipes for each planet, made in an assembler/planet related machine. productivity enabled on assembly, but disabled in silo. allows blue circuits, LDS and rocket fuel to be inserted into silo without logistics.

ingredients multiplier, rocket parts per rocket, and stack size accessible in settings, option for expensive recipes which are more complex to craft.

If paired with atan nuclear science, Nauvis rocket parts can be crafted in the nuclear forge, but requires uranium 238 for parity with other planets.
If paired with planetary fuels, they will be required to produce rocket parts, increasing complexity (recipes aren't finalised, input welcome).
