Scientists from the Physical Research Laboratory in Ahmedabad have found strong evidence of subsurface ice in craters near the Moon's south pole using data from ISRO's Chandrayaan-2 mission. The investigation focused on 'doubly shadowed craters,' which remain extremely cold due to their continuous shielding from sunlight. The Dual Frequency Synthetic Aperture Radar (DFSAR) onboard Chandrayaan-2 enabled researchers to identify radar signatures indicative of subsurface ice in four craters. Among these, a crater with a diameter of 1.1 km within the Faustini crater exhibited particularly strong evidence of ice, supported by radar observations and distinct lobate-rim morphology. The study introduces a new radar-based criterion for identifying subsurface ice, utilizing Circular Polarization Ratio (CPR) and Degree of Polarization (DOP) values. These findings have significant implications for future lunar exploration missions, especially in identifying potential ice-bearing regions for in-situ resource utilization (ISRU) activities.
