NASAs Mars rover Opportunity has made perhaps the biggest discovery of its nearly 10-year career, finding evidence that life may have been able to get a foothold on the Red Planet long ago.The Opportunity rover spotted clay minerals in an ancient rock on the rim of Mars Endeavour Crater, suggesting that benign, neutral-pH water once flowed through the area, scientists said.”This is water you could drink,” Opportunity principal investigator Steve Squyres of Cornell University told reporters today June 7, explaining why the rock, dubbed “Esperance,” stands out from other water-soaked stones the rover has studied.
