The Nasa LCROSS mission discovering water is on the Moon crashed into the surface blasting a plume of rock and dust into space.

“Millions watched live online as at 12:31pm British time an empty rocket plunged into the Moon's south pole at 1.6 miles per second. A probe followed close behind, flying through the six-mile-high shower of debris kicked up by the impact, before crashing into the surface itself four minutes later. Telescopes on Earth and instruments on the probe itself scoured the huge impact cloud to see if there is any water or ice spraying up.

Within an hour scientists claim they will be able to confirm the theory that water — a key resource if people are going to go back to the Moon — is hidden below the barren moonscape.
The sensors will scour for ice, fly through the debris cloud and then just four minutes later take the fatal plunge itself, triggering a dust storm one-third the size of the first hit.
The impact site is a 60-mile-wide hole, which lies just a short distance from the Shackleton crater – the proposed location for Nasa's manned lunar base, which it hopes to have completed by 2024.

Just a couple of weeks ago, the Indian Chandrayaan satellite appeared to confirm the existence of water in the region – subsequently confirmed by data from the Lunar Reconnaissance Orbiter, the vessel that LCROSS hitched a ride into space alongside.

It is believed water ice could lie at the bottom of dark craters at the Moon's poles, where temperatures are lower than minus 170C,” The Daily Telegraph informs.
