1998: Lunar Prospector - USA Lunar Orbiter was launched and arrived at the Moon on January 11, 1998. It is designed for a low polar orbit investigation of the Moon, including the mapping of surface composition and possible ice deposits, the measuring of magnetic and gravity fields, and the study of lunar outgassing events. This data could help scientists plan a potential lunar base and develop theories of the formation of the Moon, Earth and Solar System. Its mission is scheduled to last one to three years.
