NASA's Lunar Trailblazer mission approaches the Moon as it enters its science orbit in this artist's concept. The small satellite will orbit about 60 miles (100 kilometers) above the lunar surface, producing the best-yet maps of water on the Moon. Lunar Trailblazer will discover where the Moon's water is, what form it is in, and how it changes over time.
