Scientists think the moon's polar craters, which never see sunlight, could contain ice. A lunar water supply means that astronauts would be able to use the moon as a home base for space exploration. The US, EU, Japan, India, and China already have plans for permanent moon bases to be set up around 2025.
If astronauts begin living permanently on the moon, I don't see why nonscientists wouldn't soon pack up and move to outer space shortly after. The moon's only three days away — much shorter than the ship voyage made by Europeans moving to the New World, for example.
Would you move to a settlement on the moon? Would you worry that territory disputes could break out between settlers from different countries?
