Asteroid missions are space exploration projects aimed at studying asteroids, which are small rocky bodies orbiting the Sun. These missions help scientists understand the formation of our solar system and the materials that make up celestial bodies. Notable missions include NASA's OSIRIS-REx, which collected samples from the asteroid Bennu, and the Hayabusa2 mission by the Japan Aerospace Exploration Agency, which returned samples from the asteroid Ryugu. These missions often involve spacecraft equipped with advanced instruments to analyze the surface composition, structure, and potential resources of asteroids. By studying asteroids, researchers hope to gain insights into planetary formation and the possibility of using these bodies for future space exploration or resource extraction.
