Lunar samples refer to the rock and soil samples collected from the surface of the Moon during various Apollo missions by NASA, as well as the Soviet Union's Luna missions. These samples have provided valuable insights into the geology, mineralogy, and history of the Moon, and have helped scientists better understand the origin and evolution of Earth's closest celestial neighbor. By studying these samples, scientists have been able to determine the age of the Moon, its geological processes, and its impact history. The analysis of lunar samples continues to provide important information about the history and formation of the Moon, as well as insights into the broader evolution of the solar system.
