👉 The Mars Weapon, officially known as the Mars Surface Instrument for Radar and Electromagnetic Sounding (MARSIS), is a high-frequency radar system designed for the European Space Agency's Mars Express mission. It operates by emitting radio waves that penetrate the Martian surface, reflecting off subsurface structures and sending back data to reveal hidden geological features, such as ice deposits, subsurface water, and potential lava tubes. This technology provides crucial insights into Mars' geological history and potential habitability by mapping the planet's subsurface composition and structure.
