In the Shadow of Benben

This image shows the late-morning shadow cast by Benben Saxum, the largest boulder on asteroid Bennu. It was taken by the PolyCam camera on NASA’s OSIRIS-REx spacecraft on March 21 from a distance of 2.2 miles (3.5 km). The field of view is 163 ft (49.7 m). For scale, the smaller, square light-colored rock on the left is 18 ft (5.5 m) wide, which is about the length of a full-size pickup truck. The image was obtained during Flyby 3 of the mission’s Detailed Survey: Baseball Diamond phase. When the image was taken, the spacecraft was over the equator, pointing PolyCam south.
