New around here, I have a few modding feasibility questions before I start messing around with learning KSP modding. If any of these have been done already, I haven't been able to find them. Still trying to get a feel for what's possible and what isn't... 1) Refueling on another planet/moon via mining. The way I envision this working, we'd devise some plausible cockamamie "scientific" process for manufacturing liquid, mono, and solid fuel using just local drilling/mining and electricity. This would need to be done via EVA (need some practical uses!) or maybe robotically to gather resources & run any machinery needed to produce fuel. 1a) Prospecting and sampling needed to locate mineral rich areas to create stuff from? 1b) Possible to connect fuel hoses between fuel producing machines, base storage tanks, and vehicle storage tanks to facilitate transfers? Yeah, might be tough to make hose-like... 2) Towing or some other method of retrieval of re-usable 1st stage tanks/boosters/engines 3) Add new fuel/engine types (may be needed for the plausible cockamamie science) 4) A magnetic crane to move/build base components, or to fix up that mess of a "landing" the other Kerbals pulled off recently (i.e. point your ship upright after tipping it over) 4a) A physical "Grabber Thingy®" for a similar use as a crane, build/fix bases, etc. 5) Spawning/building base components using some manufacturing/production process similar to the fuel production concept above 100) Railgun style launches? +1000 points if you have to build the rail manually
