Asteroids are the leftover debris from the Solar System’s formation process that began more than 4.5 billion years ago. Studying Bennu will revolutionize our understanding of the early Solar System and teach us much about planetary history and the origin of life. The OSIRIS-REx mission will expand our knowledge of the hazards and resources in near-Earth space and will serve as a precursor to future asteroid missions."
The mission will take seven years from launch to return. The encapsulated sample will land in the Utah dessert in September, 2023.
