Evolution of the atmosphere and surface of Titan

摘要: Present understanding of the surface and atmosphere Saturn's moon Titan indicates that methane in stratosphere is photolytically converted to higher hydrocarbons at a rate such kilometer deep layer byproducts has accumulated over age solar system. Many these byproducts, stable as liquids under current conditions, may be part widespread, even global, hydrocarbon-methane-nitrogen ocean. The interaction this ocean with atmosphere, together progressive stratospheric destruction methane, have driven climatic evolution geologic time which left its mark bedrock, unique world. state processes reviewed. record found ice crust morphology, composition any oceans, atmospheric abundances deuterated species. In each areas key observations will made by instrument complement aboard ESA/NASA Huygens probe Cassini orbiter.
