Scientists said the "exciting" finding had gone "beyond expectations" as fully formed ice was found in a crater on the planet. They said that the ice — thought to be in granules mixed with grains of Moon dust — heralded a major leap forward in space exploration and boosted hopes of a permanent lunar base. The water was found in one mile high plume of debris that was kicked up by the LUnar Crater Observation and Sensing Satellite (LCROSS) on 9th October, 2009 when it crashed into the Cabeus crater near the Moon's south pole. The identification of water-ice in the impact plume is important for purely scientific reasons, but also because a supply of water on the Moon would be a vital resource for future human exploration. Anthony Colaprete, project scientist for the space mission, said that it should be possilbe to purify the water for drinking even though it appeared to mixed with poisonous methanol.
