Smooth Boulders in the Equatorial Region

This is a detailed view of a small area located just south of asteroid Bennu’s equator. Three relatively large boulders with a similarly smooth texture are visible in the image (lower left and upper right). 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 31 ft (9.4 m). For scale, the brightest rock in the image (upper right corner) is 3.5 ft (1.1 m) long, which is about the length of a fully-grown Great Dane. The image was obtained during the mission’s Orbital B phase. When the image was taken, the spacecraft was just south of the equator, pointing PolyCam straight down.
