Orbit Polities:

Primary Industries:

  • Callisto and Ganymede (carbonates, silicates, metals and general industry)
  • Europa (carbonates, hydrocarbons and a research technology economy)
  • Io (silicates, fissiles and an energy economy)


Geographical Features:

  • Jupiter possesses a brutal radiation field that engulfs Io and Europa, and to a lesser extent Ganymede. As a result, settlements on Io and Europa in particular are almost exclusively subterranean.
  • Jupiter proper is a popular gravitational slingshot for spaceship navigation.
