Bennu Surface (IMAGE) Southwest Research Institute Caption Using data from NASA's OSIRIS-REx mission, an SwRI-led team discovered that the surface of near-Earth asteroid Bennu is geologically older than expected. Craters and large, often fractured boulders (shown here) likely date from the time the asteroid was still orbiting in the main asteroid belt between Mars and Jupiter.
