Astronauts have discovered water on the moon

On October 9,2009, NASA let a spaceship crash into the Moon to see if water is there. NASA thought the spaceship will be covered with dust. But actually,the spaceship was not covered with dust. NASA discovered that by satelites which connected to Earth.They were so suprised. NASA is still trying to know if there's a problem with the satelite or is that what really happened. They also found water there.
