On Aug. 17, the OSIRIS-REx spacecraft obtained the first images of its target asteroid Bennu from a distance of 1.4 million miles (2.2 million km), or almost six times the distance between the Earth and Moon. This cropped set of five images was obtained by the PolyCam camera over the course of an hour for calibration purposes and in order to assist the missions navigation team with optical navigation efforts. Bennu is visible as a moving object against the stars in the constellation Serpens. Credits: NASA/Goddard/University of Arizona
