Ganymede is the seventh satellite of Jupiter and the largest moon in the Sol system. It is one of the "Galilean moons", the four largest moons of Jupiter that were discovered by Galileo Galilei.

It is the only moon with any magnetosphere making it the only place where dome-grown crops stood a chance in Jupiter's harsh radiation belt. It can be thought of as a place of harvest, and definitely a lynch pin in food economy in the belt. Large mirrors were placed around the planet, most likely to supply the Sun's light to the surface for crop growth.

It claims the lowest amount of birth defects and stillbirths. This being the case many women come to Ganymede to deliver. It is the center of what made human expansion to the outer planets possible.



Ganymede Station was one of the first permanent human settlements in the outer planets, built as a long term colony with large domes filled with food crops. It was known as the safest station in the Jovian system, and many humans from other colonies traveled to Ganymede to deliver their babies.

Viability for human populationEdit

Eros Incident Revolt Edit

During the Eros incident a revolt ended with sixteen dead.

Ganymede IncidentEdit

After the Ganymede incident and the ensuing battle above Ganymede, Ganymede Station was destroyed. Due to logistical issues it took a great deal of time to evacuate citizens from the station, often relegating those who escaped to months aboard-ship with nowhere to dock as refugees.
