Two views of a lunar natural bridge
Two views of a lunar natural bridge Two views of the natural bridge within King crater on the Moon show the advantage of using a variety of solar illumination angles to view unusual topographic features. The left image shows the bridge when the Sun was 42° above the horizon, and the right is the same area taken at a time when the Sun was 80° above the horizon (near noon). M113168034R on the left, M123791947L on the right, both are 128 meters across, north is up. NASA / GSFC / ASU
