A lunar mapping mission on behalf of NASA and the US Department of Defense, launched in January 1994. It achieved lunar orbit, completed its photographic tasks, and left orbit on 3 May, heading for asteroid Geographos. On 7 May a housekeeping computer malfunction led to the depletion of the attitude-control propellant and the abandonment of the asteroid mission. Clementine entered an Earth orbit that passed repeatedly through the Van Allen belts, from which the spacecraft continued to transmit data from its sensors.
