…The Strongest Evidence Yet For Water On Mars [sciTech]

ScienceMag – “I’m going to hear from my colleagues: ‘So, you’ve discovered water on Mars for the thousandth time?’ ” says planetary scientist Alfred McEwen of the University of Arizona in Tucson. Actually, it’s much better than that. Using the most powerful camera ever to orbit Mars, McEwen and his colleagues are reporting the strongest evidence yet for water on Mars that’s flowing, not frozen—and the water is flowing today, not a millennium or an eon ago.

At a few spots, the meager warmth of martian summer seems able to coax enough liquid water out of the ground to darken the soil in streaks. The marks, which sometimes number in the hundreds, grow downhill hundreds of meters only to fade with the winter cold. And where there is liquid water, as they say, there could be life.
