Mars rover missions

Definition

Mars rover missions are robotic explorations designed to investigate the Martian surface and gather data about its geology, climate, and potential for past or present life. These missions utilize advanced technology to analyze soil and rock samples, search for signs of water, and assess environmental conditions that could affect habitability. The information gathered helps scientists understand Mars' history and its similarities and differences with Earth, especially in relation to water delivery mechanisms and the criteria for life.
