Mine alien ore, build machines to refine it, and craft tiered rockets to blast off to new planet-dimensions full of exotic ores. A space-exploration tech mod that turns survival into a journey from your first pickaxe to interstellar travel.
Settle the planets you reached — drop a beacon, ship in supplies, and let colonist NPCs grow a self-sustaining off-world settlement that runs while you're away.
One guided path through the whole ecosystem — story missions, daily contracts, faction quests and space-race milestones that turn a pile of mods into a designed journey.
