Bennu's "spine"
Bennu's "spine" Bennu has a region of large boulders that runs like a spine from the equator down toward the south pole. This image of the top of Bennu's spine was taken by PolyCam from the northern hemisphere during Flyby 5A of the mission’s Detailed Survey: Baseball Diamond phase on 4 April 2019 from a distance of 4.6 kilometers. The triangular boulder in the center is 9.2 meters high. NASA/Goddard/University of Arizona/Processed by Jason Davis
