No need to be dried out on a dry world like Mars. A huge, easy-to-get-to watering hole appears to be available for the tapping, conveniently situated on the Red Planet. That kind of resource would be welcomed news for any future expedition in setting up a Mars camp. Not to mention scientists looking for present-day local life there. Evidence for a large ground water reservoir — capped by a relatively shallow layer of ice — exists within the Mars’ Solis/Thaumasia Planum region, says a team of scientists. The site is south of the huge Martian canyon system, Valles Marineris.
