Now, according to a series of new papers published in the journal Science, NASA's Mars Science Laboratory rover Curiosity has found that the Mars topsoil is laced with surprisingly high quantities of the wet stuff. And this could be good news for future Mars colonists. 'If you take a cubic foot of that soil you can basically get two pints of water out it — a couple of water bottles like you'd take to the gym, worth of water,' Curiosity scientist Laurie Leshin, of Rensselaer Polytechnic Institute, N.Y., told Discovery News."
