Curiosity's latest discovery should pour water on any reservations you might have had about our inevitable move to Mars. In a game-changing turn for the red planet's viability for human exploration and settlement, the plucky rover has found that Mars has practically unlimited supplies of water. Turns out the surface soil on Mars is 2 percent water, meaning every cubic foot contains around two pints that could be extracted to help sustain Earthling pioneers. "For me that was a big 'wow' moment," Laurie Leshin of Rensselaer Polytechnic Institute in Troy, N.Y., who led a study of Curiosity's first major soil analysis, told Space.com. "I was really happy when we saw that there's easily accessible water here in the dirt beneath your feet. And it's probably true anywhere you go on Mars." [Source]
