Chandrayaan-2 Detects Ice in Moon's Doubly-Shadowed Craters
India's Chandrayaan-2 spacecraft has discovered strong evidence of ice in the Moon's south pole region, specifically in 'doubly-shadowed' craters. These craters are so deep and permanently shadowed that sunlight has never reached their floors, allowing ice to remain frozen for billions of years. The discovery was made using radar data from the Chandrayaan-2 orbiter, which has been orbiting the Moon since 2019. The ice is located underground, not on the surface, and was identified by the Dual Frequency Synthetic Aperture Radar (DFSAR) instrument, which detects distinctive radar signatures of ice.
