Hidden Equatorial Ice Could Redefine Mars Missions

ESA's Mars Express radar data reveal buried, ice-rich deposits up to 3.7 km thick in the Medusae Fossae Formation along Mars' equator, hinting at a vast ancient water reservoir. If confirmed, it could provide a near-equatorial water source for future missions and shed light on Mars's climate history; direct sampling hasn't occurred yet, and SHARAD data will be used to tighten the case.
