What is a luner lander?

A lunar lander is a spacecraft designed to land on the Moon's surface, often as part of a larger mission to explore or study the lunar environment. It typically includes systems for descent, landing, and sometimes ascent back to a lunar orbit or to a spacecraft in lunar orbit. The most famous example is the Apollo Lunar Module, used during NASA's Apollo missions to transport astronauts from lunar orbit to the Moon's surface and back. Lunar landers are crucial for surface exploration and scientific research on the Moon.
