Fine-Grained Material in Bennu’s Northern Hemisphere

This image shows a small area of asteroid Bennu’s northern hemisphere that contains patches of fine-grained material. Morning shadows, cast to the left, are visible. The image was taken by the PolyCam camera on NASA’s OSIRIS-REx spacecraft on July 20, from a distance of 0.4 miles (0.7 km). The field of view is 31 ft (9.6 m). For scale, the light, rectangular rock (left) is 4.7 ft (1.4 m) long, which is about the length of a bicycle. The image was obtained during the mission’s Orbital B phase. When the image was taken, the spacecraft was over the northern hemisphere, pointing PolyCam nearly straight down.
