Titan: Earth-like on the Outside, Ocean World on the Inside

“…Theoretical investigations are exploring both the possibilities for lipid membrane-like structures in low temperature environments and whether cell membranes are even necessary (Palmer et al 2017;Stevenson et al 2015;Rahm et al 2016;Sandström & Rahm 2020). Laboratory and theoretical models are revolutionizing our understanding of the possible conditions within Titan's lakes and seas (Cordier & Carrasco 2019;Luspay-Kuti et al 2015;Cordier et al 2012Cordier et al , 2016Cordier et al , 2017Cordier & Liger-Belair 2018;Hodyss et al 2013;Corrales et al 2017;Malaska et al 2017;Hartwig et al 2018;Czaplinski et al 2019Czaplinski et al , 2020Farnsworth et al 2019). Employing these new findings to constrain the habitability potential of Titan's liquid hydrocarbons requires both determining the composition of Titan sediments-as the Dragonfly mission's plans to do by exploring at a portion of one of Titan's low-latitude dune fields-and monitoring the composition, physical conditions, and seasonal evolution of Titan's polar lakes and seas with future missions.…”
