Lunar Sample Return refers to missions that collect and bring back materials from the Moon's surface to Earth for scientific study. These samples can include rocks, soil, and other materials that help scientists understand the Moon's geology, history, and formation. The most famous Lunar Sample Return missions were conducted during the Apollo program in the late 1960s and early 1970s. Recent efforts, such as the Chandrayaan-2 mission by India and the Artemis program by NASA, aim to return new samples from the Moon. These missions are crucial for advancing our knowledge of the Moon and preparing for future human exploration, including potential missions to Mars.
