Lander
In space and astronautical engineering, a lander is a spacecraft designed to land on the surface of a celestial body, such as a planet or a moon. The main purpose of a lander is to deliver scientific instruments and equipment to the surface for exploration and research purposes. Landers can be either manned or unmanned, and they can be designed to operate for a short period of time or for an extended duration. The design of a lander depends on the specific mission requirements and the characteristics of the target celestial body, such as its gravity, atmosphere, and surface conditions. Some of the key components of a lander include a descent stage, landing legs or thrusters, scientific instruments, and communication systems.
