Ganymede, the largest moon of Jupiter and a vital agricultural hub in the Belt, emerges as a critical setting in The Expanse series, evolving from a stable breadbasket for the outer planets to a flashpoint of interstellar conflict. Its vast domed farms supply food to Belters and Martians alike, but underlying tensions between factions erupt into catastrophe, reshaping alliances and exposing covert bioweapon experiments.
