Spaceship to Smash into Moon

Nasa is going to smash a spaceship into the moon in order to see if there is hidden ice in the craters. Two spaceships are going to hit the moons south pole and scientists believe this will reveal ice inside the craters of the moons. Many people have been critical of this because it seems violent or crude but scientists are saying it is economical. The last time NASA had a lunar prospector mission it found large amounts of hydrogen in the moon's poles. NASA plans to hit the moon on a flat surface away from large rocks. This will allow the plum to rise up and be seen by telescopes. In all this mission will cost $79 million dollares.
