Details
Only moon with dense N₂ atmosphere (1.5 bar, 50% denser than Earth's). Surface at 94 K (−179°C). Hydrological cycle of methane/ethane — Kraken Mare (~400,000 km²), Ligeia Mare (~130,000 km²) are liquid hydrocarbon seas. Estimated 10¹⁵ m³ of liquid hydrocarbons on surface, plus vast dune fields of organic tholins. Subsurface water-ammonia ocean at ~100 km depth. Dragonfly rotorcraft mission (NASA, launch 2028, arrival 2034) will explore prebiotic chemistry. Potential for in-situ propellant production (methane/oxygen from surface resources). ΔV from LEO ~15 km/s.
唯一拥有稠密氮气大气层的卫星（1.5 巴，密度是地球的 1.5 倍）。表面温度 94 K（−179°C）。具有甲烷/乙烷构成的水文循环 — Kraken Mare（约 40 万 km²）和 Ligeia Mare（约 13 万 km²）都是液态烃的"海洋"。表面估计有 10¹⁵ m³ 的液态烃，外加由有机托林构成的广阔沙丘。约 100 公里深处存在水-氨次表层海洋。蜻蜓号旋翼机任务（NASA，2028 年发射，2034 年抵达）将探索前生命化学。具备就地推进剂生产潜力（利用表面资源生成甲烷/氧气）。从近地轨道出发所需 ΔV 约 15 km/s。
