Fractured Boulder in Bennu’s Northern Hemisphere

This image shows a portion of a large boulder that is located in asteroid Bennu’s northern hemisphere. The boulder has a prominent fracture running through it, and a small rock sits on top of the boulder’s left side. Long, evening shadows are cast to the right, as the image was obtained at 6:00 pm Local Solar Time. It was taken by the PolyCam camera on NASA’s OSIRIS-REx spacecraft on July 15, from a distance of 0.4 miles (0.7 km). The field of view is 31 ft (9.6 m). For scale, the small rock perched on top of the large boulder (upper center) is 1 ft (0.3 m) across, which is about the size of a sunflower in full bloom. The image was obtained during the mission’s Orbital B phase. The spacecraft was over the northern hemisphere, pointing PolyCam straight down when the image was taken.
