Powered by the Kopernicus planet creation mod, the Odysseus Planet Pack adds in a gas giant with a variety of unique moons. Included with this pack is a gas giant, four terrestrial moons, two asteroids (on-rails), and an ice giant. The Odysseus Planet Pack is intended to be a Kerbal Space Program player's first mission to a another planetary system with multiple moons, featuring just as many new challenges as there are more intermediate-level tasks. THIS PLANET PACK REQUIRES KOPERNICUS TO WORK.
