A mission typically refers to a specific task or objective undertaken by an organization or individual. In the context of space exploration, missions are designed to gather data, conduct experiments, or explore celestial bodies. For example, the Mars Rover missions aim to study the Martian surface and search for signs of past life. Missions can vary in scale and complexity, from short-term projects to long-term endeavors. They often involve collaboration among various agencies, such as NASA and ESA, and require extensive planning and resources to achieve their goals. Successful missions contribute significantly to our understanding of the universe.
