Scientists say they have detected a significant amount of water on the moon near the lunar south pole.
Now scientists are trying to figure out what's next.
NASA is thrilled their belief that there is water on the moon proved to be true in an expensive experiment last month. The water found is drinkable and plentiful.
"We found about maybe a dozen of these two gallon buckets full of water," NASA Project Scientist Anthony Colaprete said.
Now the value of the moon, from a scientific perspective, is radically increased.
"Rather than a dead and unchanging world, it could in fact be a very dynamic and interesting one," said Greg Delory of the University of California Berkeley.
The question now is: What does water on the moon mean?
One idea is to build a base on the moon then live off the land, including separating it, using the hydrogen for fuel and the oxygen for breathing.
The move would allow astronauts to have an easier time building and maintaining a lunar base NASA wants to build in 10 years. That base could be a staging point for a trip to Mars.
