An idea for the mod could be that if you build a space station or a satellite above a planet, you can mine for gases.
Such an idea could be.
Venus: you can mine sulfuric acid, which could be used to make and power battery's.
earth: collecting oxygen and nitrogen for supporting life and for ionic fuel.
Mars:This technically wouldn't be a gas but, harvesting radiation above mars, which could be used to generate power, and be compatible with mine chem to change elements.
Jupiter: mining for hydrogen to use as fuel and power generation, and mining for vaporized metals, which could be put into a gas compressor to turn it into a metal dust.
Saturn: same thing as Jupiter except you yield less gas, but you can mine the rings.
Uranus and Neptune: you can mine for nitrogen and methane in the largest abundance, to be used as rocket fuel and nitrogen for a ionic fuel, which would be a fuel consumed to travel to other solar systems.
