Regolith pond on Bennu

Regolith pond on Bennu
Regolith pond on Bennu This trio of images acquired by NASA’s OSIRIS-REx spacecraft on 25 February approximately 1.8 kilometers from the surface shows a wide shot and two close-ups of a region in Bennu’s northern hemisphere. The wide-angle image (left), obtained by the spacecraft’s MapCam camera, shows a 180-meter-wide area with many rocks, including some large boulders, and a “pond” of regolith that is mostly devoid of large rocks. The two closer images, obtained by the high-resolution PolyCam camera, show details of areas in the MapCam image, specifically a 15-meter boulder (top) and the regolith pond (bottom). The PolyCam frames are 31 meters across. NASA / Goddard/ University of Arizona
