Rahasparin

Rahasparin is a fictional celestial body featured in the science fiction novel "The Expanse" series by James S.A. Corey. It is described as a moon orbiting the gas giant planet, Polyphemus, within the fictional star system of Tau Ceti. Rahasparin is notable for its extreme temperature variations and its thin, methane-rich atmosphere. The surface is characterized by frozen methane lakes and rugged, icy terrain.

In the narrative, Rahasparin serves as a vital outpost and a resource extraction site for the Earth and Mars governments, particularly for its deposits of rare minerals. Its harsh environment presents significant challenges for human habitation and operations, requiring advanced life support and specialized equipment for any exploration or mining efforts. The moon's strategic importance in the context of inter-planetary politics and resource control is a recurring theme in the novels. Rahasparin's isolation and the dangers associated with its environment contribute to the sense of frontier exploration and conflict that defines "The Expanse" universe.
