How life may find a way on Saturn's moon

Larger than both our own moon and the planet Mercury, Titan is unique in our solar system.

Its atmospheric pressure is 60% greater than Earth’s, meaning it exerts the kind of pressure you feel at the bottom of a swimming pool, according to NASA. So it would make sense that the potential for life on Titan would have to look a little different.

Titan’s atmosphere may not be much different than that of primordial Earth’s – and life found a way here. How does Titan compare? First of all, it’s bigger than Europa and Enceladus.

NASA’s Cassini spacecraft mission to Saturn comes to an end later this year, but proposed mission concepts already exist for a type of “Titan airplane” called the AVIATR and a submarine that would explore Titan’s seas.

“Saturn’s moon, Enceladus, is the place to search for life like us, life that depends on – and exists in – liquid water,” Lunine said.

“Titan, on the other hand, is the place to go to seek the outer limits of life – can some exotic type of life begin and evolve in a truly alien environment, that of liquid methane?”.
