By the year 2025, humans may go to war to claim they own rights to the Moon.
The Moon has been found to contain an element called Helium-3. To make a really long story short, Helium-3 will be the element that provides power to the Earth beginning in the year 2050 and replace fossil fuels.
Helium-3 is emitted from the Sun but reflected by Earth because of our atmosphere and magnetic field. The Moon does not have an atmosphere or magnetic field so all the Helium-3 ejected from the Sun in the Moon's path has landed on the Moon.
Russia, China, perhaps India, and the United States are in a space race to get to the Moon by 2025 and set up mining operations. He who controls the Helium-3 will be all powerful.
The problem is, how do you get water up to people colonizing the Moon? You cannot fill a rocketship full of water because it would be way too massively heavy to launch.
However, if water was already up on the Moon, you could filter it and the people living on the Moon could use it to bathe and drink.
THAT is why NASA has to find out whether the Moon contains water.
