Dielectric Measurements of Saline Ices: Implication for Jovian Satellites Radar Exploration

of Jupiter’s moon Ganimede. Recently, Marsis and Sharad missions on Mars showed the capability of orbiting radar sounder, to detect the subsurface features of the planet .Therefore, the use of such techniques could prove the presence of a subsurface Ganimede ocean. The achievement of such an objective depends on the electromagnetic properties of Ganimede ice shell, which in turn will depend on the ice’s purity and temperature gradient, as well as on the radar wavelength. In this scenario, we have performed measurements of dielectric properties of pure and saline ice (mixing MgSO4 or Na2SO4 with bidistilled water) both in time and frequency domain. Both methods set show the capability of TDR and LCR techniques to estimate the electromagnetic properties of salty ice.
