Vesta is an oddity in the system, built as the an experiment for living in a cylindrical colony using centripetal to simulate gravity and contain atmosphere. The experiment was wildly successful and resulted in the creation of Oberon station in Earth’s L5.
Vesta is the Agricultural hub of the asteroid belt. It grows all of the crops consumed in the region as well as a large part of the meat. Fish and a few other specific foods are imported, most notable from Ganymede.
