Background Clementine was placed in lunar orbit on February 19, 1994, completing its highly successful lunar mapping mission. Clementine left orbit in early May 1994, but not before amassing a collection of 1.8 million lunar images. Clementine offered many benefits to the U.S. space program. Along with its primary military mission to qualify lightweight technology, it returned valuable lunar data for the international civilian scientific community that exceeded mission science objectives. Clementine showed the capability of the national laboratories, working in conjunction with DoD, NASA, industry, and international space organizations, to integrate, execute, and operate meaningful space missions at low…
