Main Belt
Asteroid Vesta was at one time host to prospecting facilities for examination of the local belt. However the rock itself has been mined thorougly, with many deep shafts bored into its marred surface. It has since become an ISA training facility, near the organization's official boundary.
Ceres
Located within the local asteroid belt, Ceres houses several asteroid mining facilities. These facilities serve as mining camps for Ceres itself as well as headquarters for the various mining fleets that prospect and harvest the other asteroids of the belt.
Pallas
This stony body houses one of the few asteroid based production facilities. Its factories are devoted almost completely to the production of industrial parts for the mining vessels that frequent the area.
Hygiea
The fourth largest asteroid within the asteroid belt, Hygiea has become a popular stopover for mining vessels in the area. Its location making it a good landing pad of sorts. Due to this it has seen a recent upstart grace its surface, looking to sell commodities to the weary crews of these ships.
