Four images of Alphonsus from 15 km

Earth's Moon
These four images of the floor of Alphonsus crater were taken on 24 March 1965 about 5 seconds before Ranger 9 impacted on the surface. The pictures were taken by the four P-series cameras, and are (clockwise from upper left) P3, P4, P2, P1. The P3 image was taken from 14.3 km and is about 1.6 km across. The P4 image is 1.5 km across, taken at a distance of 13.1 km. P2, taken from 13.6 km, is 540 meters across, and P1, from 14.7 km, is 580 meters. North is at 1:00 for all four images.
