ARDI: Darwin's theory with the days numbered.

The U.S. space agency NASA is preparing to launch on Friday a 2.3-ton projectile into a crater on the Moon's south pole, followed by a probe to look for water. The probe, called LCROSS (Lunar Crater Observation and Sensing Satellite) was launched into space in June aboard an Atlas V rocket, along with the LRO (Lunar Orbiter Reconaissance), responsible for drafting a detailed letter of single satellite Earth's natural. The two devices make up the first mission of the Constellation program, which provides for the return of man to the moon from 2020.
The LCROSS spacecraft traveled to the moon for three months, adhering to a phase called Atlas Centaur rocket. Both devices will be launched this Friday to the lunar crater Cabeus. Centauro
Cabeus crash into the 11H30 GMT on Friday at a speed of 9,000 km per hour, creating a crater 20 meters across and five deep.
The impact sent 350 tons of material about 10 miles high at a time when the sun's rays provide the maximum illumination.

LCROSS probe of a mass of 891 kg, will suffer the same fate four minutes later, the time required for nine instruments, among which are three spectrometers, can capture and determine the nature of the particles ejected, before transmitting collected data to Earth.

This will determine whether water is frozen in a crater that never receives sunlight and has an average temperature of -240 degrees Celsius.
