Touchdown on asteroid Bennu! Rocks fly off asteroid Bennu after NASA's OSIRIS-REx spacecraft touched the surface to collect a sample on 20 October 2020. The sample head touched Bennu's surface for 6 seconds while a bottle of nitrogen gas stirred rocks and fine-grained material into a collector. The spacecraft then backed away using its thrusters, as debris filled the camera view. NASA/Goddard/University of Arizona
