The official name for Clementine is Deep Space Probe Science Experiment (DSPSE). It was a Department of Defense program used to test new space technology. Clementine was a new design using lightweight structure and propellant systems. Its four cameras mapped the surface of the Moon at 125-250 meters/pixel resolution. Clementine also used a laser to gather altimeter data which will make it possible to generate the first lunar topographic map.
