Polar layered deposits are extensive formations of ice and dust layers found at the poles of Mars and other planetary bodies. These deposits are thought to have formed over thousands to millions of years through processes such as seasonal climate variations, dust storms, and deposition of ice from atmospheric water vapor. Studying polar layered deposits can provide insights into the geological history, climate, and past environmental conditions of these planets, as well as potential resources for future human exploration.
