Mars rover Opportunity finds sign of 'water you could drink'
NASA’s Mars rover Opportunity has scraped away at some of the oldest rock it's examined and found the strongest signs for water it has ever discovered over its 9.5-year mission, scientists for the Mars Exploration Rover project said Friday. The scrappy little rover is now heading down Endeavour Crater’s rim to Solander Point, on what is in some ways a brand new mission, officials said.
"We consider it 'Sol 1' all over again for Opportunity," said John Callas, the mission’s project manager at the Jet Propulsion Laboratory. A sol is a Martian day.
Just before leaving a spot called Cape York on its southbound journey, Opportunity examined a rock called Esperance using its X-ray spectrometer and microscopic imager, finding clear evidence that it held clay minerals that had been altered by water – a whole lot of it. It's a far cry from many of the previous findings on Martian moisture, said mission lead scientist Steve Squyres of Cornell University.
"We run around talking about 'water on Mars, water on Mars' -- in fact, what Opportunity has mostly discovered evidence for in the past was sulfuric acid on Mars," Squyres said. "What we have here is a very different chemistry.… This was water you could drink."

Well, at least it'd be well chilled. One could certainly drink that. If they find that, I might be talked into trying out for the Mars One one way trip.
