Astrobiology on Titan

Concepts Titan - the test case Physical and chemical properties of the only other body in our solar system with a significant atmosphere 

Atmospheric structure Composition of N2 and CH4 with a complex hydrocarbon/Chapman layer structure 

Cryovulcanism Origin of the nitrogen in Titan s atmosphere may be due to the photolysis of ammonia erupting in water-ice slurries from volcanoes at low temperatures 

Atmospheric chemistry Temperature dependence dictates that all neutral chemistry is frozen out at the surface temperature of 92 K. What of radical-driven chemical networks Stratospheric chemistry at 170 K 

Liposphere The circulation of hydrocarbon-based materials in Titan s atmosphere, which is analogous to the hydrosphere (water cycles) on Earth
