FOUNDATIONS / PLANETARY PROFILES
Saturn is a gas giant primarily composed of hydrogen and helium, distinguished most notably by its extensive, intricate ring system made of billions of particles of ice and dust. It has a complex and dynamic atmosphere with high-velocity winds and a massive, rotating magnetic field. For New Horizons, Saturn is a premier laboratory for studying ring dynamics—which mirror the formation of planetary disks—and exploring high-interest moons like Titan, which possesses a thick atmosphere and liquid hydrocarbon seas.
FOUNDATIONS / STRATEGY
Learning about Saturn is vital because it acts as a gateway to understanding planetary disk formation and prebiotic chemistry. Its ring system provides real-time data on how celestial disks organize matter, while its moons—specifically Titan and Enceladus—offer the most promising environments for studying organic chemistry and sub-surface ocean potential outside of Earth. By studying Saturn, we refine our ability to conduct long-duration deep-space missions and expand our knowledge of the conditions necessary for life.
