NASA has splashed water on the argument that the moon is a dry, desolate place.

It was only a month ago that NASA crashed rockets into the permanently shadowed region of Cabeus cater near the moon’s south pole. The impact created a plume of material from the bottom of the crater that has not seen sunlight in billions of years.

Now comes news that scientists who have been analyzing data from that plume since the October 9 impact find that “It is safe to say Cabeus holds water,” according to Anthony Colaprete, project schientist for the Lunar CRater Observation and Sensing Satellite, or LCROSS. “We are ecstatic.”
