An anonymous reader writes "The folks at NASA, obviously looking for new ways to explore the universe, are planning to crash a two-ton probe into the moon. The goal? To find water." From the article: "NASA plans a series of robotic precursor missions including the Lunar Crater Observation and Sensing Satellite, or LCROSS, which will plow into the crater, and the mapper, called the Lunar Reconnaissance Orbiter. When LCROSS strikes the crater, it is expected to create a hole 16 feet deep and send up a 2.2 million-pound (998,000-kg) plume of debris for sensors and cameras stationed on a second spacecraft to monitor. Dozens of ground-based telescopes, as well as possibly space observatories, such as the Hubble telescope, will be trained on the plume as well."
