NASA to moon: Get ready because here we come

Very cool stuff , this would be the second time NASA has slammed a probe into the Moon looking for signs of Ice !

WASHINGTON — Two NASA spacecraft are barreling toward the moon at twice the speed of a bullet, about to crash into a lunar crater in a search for ice.

If all goes well, the impact will be beamed back live to Earth.

The first and much bigger crash is set for 7:31 a.m. EDT. That's when an empty rocket that weighs 2.2 tons should hit the crater Cabeus and create a minicrater about half the size of an Olympic pool. It should kick up a plume of lunar debris about six miles high.

The idea is 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.

Trailing behind the rocket is the lunar probe LCROSS, short for Lunar Crater Observation and Sensing Satellite and pronounced L-Cross, beaming back to Earth live pictures of the impact and the debris plume using color cameras. It 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.

Telescopes around the world — including the orbiting Hubble Space Telescope — will aim their cameras at the big event to provide more views of the dust-up.

LCROSS and its bigger rocket stage launched together last June and only separated Thursday night, the last major milestone before the big crash.
