Our knowledge about Titan, the largest of Saturn's moons, has improved substantially as a result of the Cassini (aka Cassini-Huygens) Mission. Titan's surface represents a prebiotic environment, rich in complex organic compounds, with a possible subsurface liquid ocean, representing a potentially biotic environment. Therefore, although life itself may not exist, the prebiotic conditions on Titan and the associated organic chemistry remain of great interest in understanding the early history of the terrestrial biosphere. Impact cratering can be used to develop constraints on the thickness of ice shells in icy planetary bodies and to model the depth of subsurface oceans, as well as the boundary conditions at the interface between the ice shell and the subsurface ocean. The objectives of this project comprise the application of numerical modeling of impact processes against Titan's icy surface to simulate the formation of impact craters in order to probe its connectivity to the lower layers, as well as the thickness and structure of the ice shell.
