Water on the Moon?

About to years ago Faith Vilas, director of the Multiple Mirror Telescope in Arizona, developed a sideline obsession with the Moon. Perusing archived data from the Galileo mission to Jupiter, she saw something different in the pictures taken of the Moon. When she started to study that picture for certain infrared wavelengths, a telling signal popped out at a few spots near the Moon's south pole. The signal, at least in asteroids, is associated with phyllosilicates, which are minerals that need two things to form: heat and water. Was this a clue pointing to all the water ice that many think hides within the Moon's polar craters?
