Description

As the agency reported it.

Evolution of fluvial landscapes on titan: channel erosion, sediment generation and methane infiltration recent exploration of titan has revealed a surface heavily modified by flowing liquids, presumably liquid methane. We propose' a laboratory and theory based approach to understanding fluvial erosion on the surface of titan. Our investigation has three main areas of research concentration. First, we wish to understand the possible mechanisms of sediment production on titan. This will be accomplished by a thorough theoretical investigation of terrestrial sediment production processes as applied to available titan materials and conditions. Second, we wish to understand the resistance of ICE bedrock on titan to erosion by sediment-carrying streams. This will be accomplished by testing ICE bedrock samples in a specialized cryogenic abrasion mill, similar to abrasion mills that have been previously used to understand terrestrial erosion rates in fluvial bedrock channels. Finally, we wish to understand the infiltration of liquid methane into the soil of titan, which will affect expected surface runoff during rainstorms, the supply of pore fluid to feed springs, and the underground transport of fluids on titan. This will be accomplished by testing the flow of liquid methane through simulated titan regolith in a cryostatic chamber. The angle of repose and liquid limit of regolith simulants will also be tested by tilting the chamber. Understanding fluvial erosion on titan not only deepens our understanding of fluvial processes in general, but is also an integral part of understanding the surface geology of this body, which is necessary in order to understand the evolution of titan as compared to other large ICY satellites in the outer solar system.
