What is the purpose of a lander in space?

A lander in space is designed to safely deliver scientific instruments, equipment, or rovers to the surface of a celestial body, such as a planet or moon. Its primary purpose is to conduct experiments, gather data, and analyze the environment of that body. Landers typically feature systems for landing safely, communication with Earth, and often have the capability to operate autonomously or remotely. Overall, they play a crucial role in expanding our understanding of the universe.
