ClementineA joint mission launched in 1994 by NASA and the US Strategic Defense Initiative Organization with the main aims of testing sensors and spacecraft components over a long period of exposure to the environment of space and carrying out scientific observations of the Moon and the near-Earth asteroid (1620) Geographos. The observations were intended to facilitate a thorough analysis of the surface relief and geology of both the Moon and Geographos by means of imaging at various wavelengths throughout the spectrum from infrared to ultraviolet, laser-ranging altimetry, and charged-particle measurement. The original purpose of these observations was to assess the surface mineralogy of the Moon between lunar latitudes 60° N and 60° S. The probe used for the Clementine mission was launched on Jan. 25 1994 from Vandenberg Air Force Base and achieved lunar orbit on Feb. 21. After completing its lunar investigations on May 7, the Clementine craft was about to maneuver into position to begin the journey to Greographos, when an onboard computer malfunction caused a thruster to fire and remain firing until it had exhausted all its fuel, sending the probe into an uncontrollable spin. Although Clementine remained in an Earth-centered orbit testing its equipment, the planned flyby of Geographos had to be abandoned. Despite being only partially successful, Clementine provided a wealth of photographic and other data. In 1996, analysis of its results led scientists to speculate that there might be reserves of water ice lying beneath the Moon's surface in deep craters whose interiors are in permanent shadow at the lunar poles.
