Mercury
ScorchedA scorched, cratered world stripped bare by Sol's radiation. Rich in heavy metals from billions of years of meteorite impacts.
The Mercurian surface is every bit as inhospitable as the records suggest, though no amount of data quite prepares you for the sheer visual aggression of it—a landscape of charcoal and rust, so thoroughly hammered by solar winds that the craters seem to nest inside one another like some cosmic Russian doll. What interests me more than the pummeled topography is the concentration of iron and nickel in the subsurface; after six centuries of surveying, I've learned that worlds this brutalized often yield unexpected bonuses, and I'd wager there's a fair bit more to extract here than the usual surveys report. Still, it's a place that reminds you why we explore from orbit when possible—Sol's furnace keeps even a seasoned captain humble.
