Objective
In the near future a number of space missions will aim to study the icy Galilean satellites of Jupiter to detect subglacial liquid water, using radar sounders. To properly interpret the radar data, it is necessary to understand the dielectric properties of the icy shells of these bodies, as they control radar signal penetration and anomaly (i.e., water) detection. The current knowledge of these properties for the types of water ices believed to be present is limited, which would potentially produce incorrect interpretations of the radar data, thus risking the scientific goals of these missions. Based on extensive experience in characterizing the dielectric properties of planetary analogues, which led me and my group to discover the first extraterrestrial subglacial stable body of liquid water on Mars, we intend to develop new methodologies and protocols to create a groundbreaking knowledgebase that fills this critical gap. We will apply the first of its kind methodology for conducting dielectric measurements across a wide range of frequencies (including the challenging interval used by these radar systems) and temperatures representative of the different ice-forming environments, produce groundbreaking studies on the structural and chemical behavior of different ice types using CT microtomography and molecular dynamic modelling, and will create a wide-ranging dataset of the dielectric properties of non-terrestrial ices. Such pioneering and high gain research will allow to obtain the maximum benefit from missions such as JUICE and Europa CLIPPER. By the end of the project significant and fundamental progress will be made to properly perform dielectric measurements on icy planetary analogues, in the comprehension of the physics behind the dielectric behavior of water ice and icy materials, and in radar data modelling and interpretation. Moreover, the project’s results will serve as a critical knowledge base for present and future radar sounder planetary missions.
