A Boulder on Bennu's Surface (IMAGE) University of Arizona Caption This composite image of a boulder on Bennu's surface shows the cascading rim of one of the asteroid's ancient craters that originated while Bennu resided in the asteroid belt. The image combines photos from OSIRIS-REx and reconstructed shape models built from the OSIRIS-REx laser altimeter instrument. The overlaid colors highlight the topography of the boulder (warmer colors are higher elevation).
