The discovery of water on the moon will bolster Nasa's long-term goal of establishing a permanently crewed outpost there. The space agency is developing a new generation of rockets and crew capsules capable of reaching the moon which are due to fly within five years of the space shuttle fleet being retired next year.
Since the Apollo missions brought back the first clumps of lunar soil and rock in the 1960s, scientists have worked on the assumption that the moon is bone dry. Small traces of water found in some of the samples were dismissed as contamination picked up while the material was being handled on Earth.
