Mars

Terran
The first terraformed world. Industrial heart of Sol.
The rusty old girl hasn't changed much since my last visit—still that same burnt-orange sprawl of mines and refineries stretching across Olympus Mons's shadow. I suppose that's the point of successful terraforming: you terraform it once, then spend the next three centuries arguing about water rights and ore quotas instead of marveling at what you've accomplished. Still, there's something grimly satisfying about a world that went from "impossible desert" to "industrial powerhouse," even if the bureaucrats at Hellas Station have made it about as inspiring as a spreadsheet.
