On October 9th of this year, NASA crasheed a rocket into the surface of the moon. The impact sent a (somewhat anti-climactic) plume of debris into the LCROSS satellite so that it could read it for evidence of water.
And guess what? They found it!
There is water on the Moon, scientists stated unequivocally on Friday, and considerable amounts of it.
“Indeed yes, we found water,” Anthony Colaprete, the principal investigator for NASA’s Lunar Crater Observation and Sensing Satellite, said in a news conference.
The confirmation of scientists’ suspicions is welcome news both to future explorers who might set up home on the lunar surface and to scientists who hope that the water, in the form of ice accumulated over billions of years, could hold a record of the solar system’s history.
