Graduated Boulder Sizes

This image shows a rocky patch in the northern hemisphere of asteroid Bennu where the rocks and boulders are situated by size. It was taken by the PolyCam camera on NASA’s OSIRIS-REx spacecraft on March 29 from a distance of 2.1 miles (3.4 km). The field of view is 157 ft (48 m). For scale, the little rock sitting on the boulder in the lower left corner is 8 ft (2.5 m) wide, which is about the same length as a horse. The image was obtained during Flyby 4B of the mission’s Detailed Survey: Baseball Diamond phase. When the image was taken, the spacecraft was over the northern hemisphere, pointing PolyCam slightly to the south.
