Mixed Rocks on Prime Meridian Boulder

This image shows a variety of rock types situated on asteroid Bennu’s prime meridian boulder, located in the southern hemisphere. Both rough and smooth textures are present, as well as contrasting sizes and brightness. The image was taken by the PolyCam camera on NASA’s OSIRIS-REx spacecraft on July 2, from a distance of 0.4 miles (0.7 km). The field of view is 30 ft (9.0 m). For scale, the crack in the boulder (lower right) is 8 ft (2.5 m) long, which is about the length of a horse. The image was obtained during the mission’s Orbital B phase. When the image was taken, the spacecraft was over the southern hemisphere, pointing PolyCam straight down.
