Resource empire building

Long-term success in Solar Expanse: Space Exploration Manager hinges on chains, not single nodes. A profitable asteroid program runs prospector → classification → mining station → processing → transport → market, with fuel and maintenance loops closing along the way. Weak links show up as idle tonnage, missed windows, or evaporating margins.

Asteroid mining chain

Start with telescopes and prospectors to rank targets by metal grade, water fraction, and accessibility. High metal and water bodies often yield better returns because they feed both industry and propellant economies. Deploy miners with enough autonomy to handle light-time gaps, and stage refining close to demand when haul costs dominate. Redirect maneuvers should be planned like flights: if you cannot explain the Δv bill, you are guessing.

Fuel depots turn sporadic mining into a network effect. Position depots on arcs that intersect multiple customers—lunar ascent tugs, Mars cargo, or deep probes. Each depot needs custody plans: boiloff management, debris avoidance, and theft or collision contingencies where the simulation models them.

Transport fleets and scheduling

Fleets fail through mismatch: tugs that cannot berth your containers, tugs with the wrong thrust profile for your window stack, or maintenance cycles that collide with peak seasons. Standardize interfaces and limit exotic one-off craft unless the contract premium justifies the spare-parts tax.

Integration with colonization

Offworld bases need steady mass and energy inputs. Align mining outputs with habitat expansion, life-support consumables, and construction volatiles. When terraforming ramps, prioritize feedstock that the atmosphere plants can actually ingest—volume without chemistry is useless.
