Abstract
This review synthesizes current knowledge of Enceladus as an Ocean World, with emphasis on habitability, organic chemistry, and the search for life. We summarize data obtained by the Cassini spacecraft, including the discovery and characterization of Enceladus’ plume and subsurface ocean. We assess how plume materials constrain the composition of the ocean, while highlighting uncertainties introduced by fractionation through transport and possible ice–ocean interface processes. We further examine how ocean dynamics and plume–ocean connectivity may shape the transport and transformation of dissolved and particulate species from the moon’s interior to space. We consider possible sources of chemical energy, redox disequilibria, and abiotic organic carbon, and how they could constrain ocean biomass, biological productivity, and the detectability of potential biosignatures. Finally, we evaluate near-term exploration strategies and mission architectures for testing theories of habitability, chemical evolution, and possible life beyond Earth.
