Patches of Fine-Grain Regolith

This image shows patches of fine-grained material located in asteroid Bennu’s northern hemisphere. Taken at 6:15 a.m. Local Solar Time, it reveals long, morning shadows cast to the left. The image was taken by the PolyCam camera on NASA’s OSIRIS-REx spacecraft on July 25, from a distance of 0.4 miles (0.7 km). The field of view is 32 ft (9.7 m). For scale, the bright boulder in the top center of the image is 5.6 ft (1.7 m) across, which is the length of a motor scooter. 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 straight down.
