The Age of Sample Returns.

Sample-return missions have greatly advanced our knowledge of the solar system by allowing scientists to study uncontaminated material from planets, asteroids, comets, and space. These missions, such as Apollo, Luna, Hayabusa, Stardust, and OSIRIS-REx, have provided valuable information about the geology, chemistry, and formation of celestial bodies. Notable missions include OSIRIS-REx, which collected material from the asteroid Bennu, and Chang'e 5, which returned lunar regolith from the Moon. Future missions, like Chang'e 6 and the Martian Moons Exploration (MMX) mission, will continue to contribute to our understanding of celestial bodies. These missions are crucial in uncovering the history and formation of the solar system. [Extracted from the article]
