Flowing Water Found on Mars?

NASA photos make a good case for there being good ol' H2O (with a healthy amount of salt) flowing through the Martian highlands.

New images from Mars make a pretty good case for there being flowing water in the mountains of the red planet, according to NASA. The space agency's Mars Renaissance Orbiter took photos of the planet's massive mountains over the course of a year and found that there were dark streaks in warmer months that weren't there during the cold ones, leading the project's researchers to figure that those markings are traces of flowing, salty water in the Martian highlands. If there is water on the otherwise dry and fairly inhospitable planet (we've all seen Total Recall), then the chances of Mars being able to support life increase dramatically. So, when we finally go and ruin this planet via nuclear war or environmental degradation or massive war with the animals or what have you, at least we know where to go next for our water supply.
