11:00 am Natalie Wolfenbarger Stanford University Brine, salt, and everything ice: Ingredients for interpreting future radar observations of Europa
Abstract: Evidence of sub-ice oceans hidden beneath the surfaces of icy moons has extended the search for life beyond Earth within our Solar System from Mars to the outer planets. However, it is the evidence for surface-ice-ocean exchange that has brought Jupiter’s ice-covered moon Europa to the forefront in the search for habitable worlds. The heavily cracked and mottled surface hints at an even more dynamic and heterogeneous subsurface, capable of transporting food, in the form of radiolytically-produced surface oxidants, to the potentially inhabited ocean below. Upcoming missions to Europa will conduct detailed reconnaissance of the moon using a suite of remote sensing and in situ instruments. Of these instruments, ice-penetrating radar is uniquely capable of contributing a third dimension to observations of Europa. In this presentation I will describe a novel approach which uses geochemical models to guide the interpretation of radar echoes from Europa’s subsurface, enabling these critical subsurface properties and processes to be constrained and characterized.
