Martian soil, also known as regolith, is the material covering the surface of Mars. It is composed of a mixture of fine dust, sand, and rocks, and is very different from the soil found on Earth. Studying Martian soil is important for understanding the geological history of Mars, potential for supporting life, and planning future human missions to the planet. Researchers analyze the composition, structure, and physical properties of Martian soil through rovers, landers, and remote sensing instruments to uncover clues about the planet's past and present conditions.
