Morning Shadows on Crater and Dark Boulder

This image of a region near asteroid Bennu’s equator shows both one of the darkest boulders on the asteroid (lower left) and a candidate sample collection site for NASA’s OSIRIS-REx asteroid sample return mission (upper left). The image was taken April 4 by the PolyCam camera on the OSIRIS-REx spacecraft from a distance of 3 miles (4.9 km). The field of view is 225 ft (68.6 m). For scale, the larger light-colored rock in the candidate site crater is 16 ft (4.8 m) long, which is about the same length as a box truck. The image was obtained during Flyby 5A of the mission’s Detailed Survey: Baseball Diamond phase. When the image was taken, the spacecraft was over the northern hemisphere, pointing PolyCam down and west in order to capture the morning shadows in the region.
