If you’re planning on heading to the moon any time soon, you’ll at least be able to get a drink. NASA announced today that the Lunar CRater Observation and Sensing Satellite has discovered water on the moon. The mission intentionally crashed a rocket stage onto the moon’s surface, creating an enormous plume of ejecta. When the plume was analyzed by spectrometers on board the satellite, the evidence of water became clear. In the photograph, you can see the debris plume showing up as the little gray fuzzy area inside the black boxes.
There are many ways the water could have gotten there. It could have come via solar winds, comets, giant molecular clouds or some kind of internal activity. Scientists say that it could even have come from Earth.
