NASA's Curiosity Finds Water Once Flowed On Mars

[skynet]

With the possibility of an infinite space outside our microscopic world, or a universe that is so large that it might as well be infinite... isn't anything possible? There's obviously an unmeasurable quantity of water in the universe. Should we be excited about water on Mars? There are probably planets that are entirely made up of water or something.

Probably anything you can think of exists somewhere out in space. Just because we haven't found it yet doesn't mean it doesn't exist. Even a lot of the things we think we already know are not what we think they are. Paradigm shifts are always on the way.

Well, I guess it's still kind of interesting.

NASA's newest Mars rover, Curiosity, has snapped photos of rocky outcroppings that jut out from the alien soil, and scientists say they look like the remnants of an ancient stream bed where water once flowed on the surface of the red planet.

The exposed rocks look like broken slabs of concrete sidewalk, about four inches thick, and are made of rounded bits of gravel in a sandy matrix. The rock has eroded a little bit, and some of the smooth pebbles — about the size of M&M candies — have fallen down into a little pile.

Scientists looked at all this and came to this conclusion: "This is a rock that was formed in the presence of water," says John Grotzinger, project scientist for the mission at the California Institute of Technology.

And not just any water, but a flowing stream.

Scientists have believed for a long time that Mars once had liquid water on its surface. Orbiting spacecraft can see canyons that must have been carved by water. In fact, researchers deliberately picked Curiosity's landing site because it looked like a place where a canyon stream had spilled water onto a plain — and now it looks like they were right.
