1998 – Launch of NASA’s Lunar Prospector spacecraft, designed and built at Lockheed Martin Missiles & Space in Sunnyvale, CA. This low-cost orbiting mission was the first of NASA’s  Discovery class of “faster, better, cheaper” space exploration missions. The $63 million mission, managed by NASA Ames Research Center, returned important science data  answering long-standing questions about the Moon. Its primary mission lasted one year. The final task will be to impact a crater rim on July 31, 1999 in order that large telescopes can collect images that may prove water does exist at the lunar poles.
