This image shows a view across asteroid Bennu’s southern hemisphere and into space, and it demonstrates the number and distribution of boulders across Bennu’s surface. The image was obtained on March 7 by the PolyCam camera on NASA’s OSIRIS-REx spacecraft from a distance of about 3 miles (5 km). The large, light-colored boulder just below the center of the image is about 24 feet (7.4 meters) wide, which is roughly half the width of a basketball court.
Currently the @osiris_rex spacecraft is orbiting Bennu, sending back images and data as it studies this massive asteroid for two years. It will collect a sample from the asteroid and send that sample back to Earth.
