Lunar Prospector, built for the NASA Ames Research Center by Lockheed Martin, is a spin-stabilized spacecraft designed to provide NASA with the first global maps of the Moons surface and its gravitational magnetic fields, as well as look for the possible presence of ice near the lunar poles. It will orbit the Moon at an altitude of approximately 63 miles during a one-year mission. The launch of Lunar Prospector is now scheduled for Jan. 6, 1998 at 9:28 p.m. EST.
