Guide to all major locations in The Expanse: Osiris Reborn, including Eros Station, Ceres Station, Ganymede, Mars, Luna (Lovell City), Io, Pinkwater Station, and the asteroid belt.
Eros Station is the asteroid station where the story of The Expanse: Osiris Reborn begins, the site of the protomolecule outbreak that triggers the game's central conspiracy.
Ceres Station is a major social hub in The Expanse: Osiris Reborn, the largest colony in the Belt, where players shop, meet NPCs, and navigate Belter culture and OPA politics.
Mars is the fourth planet from the Sun and the homeworld of the Martian Congressional Republic (MCR). In The Expanse: Osiris Reborn, Mars is a visitable location featuring imperious political bastions, military installations, and terraforming infrastructure.
Ganymede is Jupiter's largest moon, known as the breadbasket of the outer planets in The Expanse universe. Its domed agricultural greenhouses and orbital mirror network feed millions across the Belt. Ganymede is a visitable location in The Expanse: Osiris Reborn, featuring lush gardens, underground facilities, and connections to the protomolecule conspiracy.
Luna (Earth's Moon) is a visitable social hub in The Expanse: Osiris Reborn, home to Lovell City, the United Nations capital, Bush Naval Shipyards, and the solar system's most important diplomatic center.
Io is one of Jupiter's Galilean moons and the most volcanically active body in the solar system. In The Expanse, it hosts Prospero Station, a secret research facility where Project Caliban created protomolecule-human hybrid soldiers. Io is a late-game location in The Expanse: Osiris Reborn.
