The results of the Cassini/Huygens mission raise many questions about the source and fate of methane on Titan. Understanding the methane cycle on Titan is key to understanding its past history and future evolution and provide a context for considering life on Titan that uses methane for its biological solvent. Dr. McKay, a member of the Huygens science team, will describe a new model for Titan's geological cycle that may indicate it's current thick atmosphere is a transient phenomenon.

Bullseye! V good clear talk if you are interested in LIFE. IMO Chris's key points 1. Understand the movements of liquids. 2. Depletion - if life, particularly need to check if H2 at 0.1% of atmos concentration is depleted near surface.. but no depletion yet found.
However, with our current level of knowledge, v hard to kown what would be DEFINITIVE signs of life in such a complex atmosphere/surface structure at Titan?
Looking forward to him coming back and updating us all!! Hᴜɢʜ ..TU...ツ

This is unreal, totally out of my league, but I am so sick of the cookie cutter titan videos on the internet. This heavy hitting stuff is much more engaging.
