This is very good news. Any serious space exploration effort is much less costly if the moon can be used as a base — outside the earth’s deep gravity well. We can mine many of the required metals on the moon, but the cost of ferrying liquid water from earth is staggering.
Suddenly, the moon looks exciting again. It has lots of water, scientists said Friday â€” a thrilling discovery that sent a ripple of hope for a future astronaut outpost in a place that has always seemed barren and inhospitable.
Experts have long suspected there was water on the moon. Confirmation came from data churned up by two NASA spacecraft that intentionally slammed into a lunar crater last month.
“Indeed, yes, we found water. And we didn’t find just a little bit. We found a significant amount,” said Anthony Colaprete, lead scientist for the mission, holding up a white water bucket for emphasis.
The lunar crash kicked up at least 25 gallons and that’s only what scientists could see from the plumes of the impact, Colaprete said.
