The Science From Asteroid Sample Return Missions
To date, three samples from near-Earth asteroids have been delivered to Earth by Japan’s Hayabusa (2010) and Hayabusa2 (2020) missions, and the United States OSIRIS-REx mission (2023).

This specimen shows the most common types of crack networks observed in Bennu samples. One has an extensive and connect framework of curved cracks, whereas the other has sparse, straight and flat fractures.
