Deimos

Small Martian moon equipped with a deep radar station, destroyed early in the system-wide conflict.

Deimos, the diminutive Martian moon harboring a vital deep radar station, meets a swift and fiery end in the opening salvos of the solar system's escalating conflict in Leviathan Wakes. Its destruction underscores the fragility of strategic outposts amid interplanetary tensions between Earth, Mars, and the Belt. Across the expansive Expanse series, Deimos remains a poignant early casualty, its loss rippling through the narrative as a stark reminder of the high stakes in the brewing war, with no subsequent revival or redevelopment.
