I assume there's some stupendously easy way around this, but I don't know it.
I'm playing my first long game, and getting to that point where earth is starting to run down on minerals. I wasn't given the best starting system, so I'm a little low on minerals in the Sol System itself.
fortunately, I've found some good mining potential in nearby systems.
Here's the problem: I don't want to micromanage constantly shipping minerals from this planet to Earth. Is there some way to establish a dedicated shipping line to move, say, duranium and neutronium from Planet A to Planet B once every year?
