. There’s water on the Moon.
Seems a huge surprise given the Moon has practically no atmosphere, but it’s true: there is frozen water lurking in permanently shadowed craters, and potentially below the soil itself. The water may have been blown in by the solar wind or deposited by comets, but scientists are still probing its origins. No one is sure if there is enough ice there to support a human colony, but the potential is exciting; it may mean we don’t have to truck this heavy but essential good from Earth.
