Evidence of ancient water is found byMars Exploration Rover Opportunity, according to a paper published in the May 4 edition of the journal Science entitled, “Ancient Impact and Aqueous Processes at Endeavour Crater, Mars.” The latest discovery was made at the rim of the Endeavour Crater, a large ancient impact crater on Mars measuring 14 miles in diameter.The rover discovered evidence for low temperature liquid water and environments that would be conducive for life.Opportunity was one of two exploration rovers that landed on Mars eight years ago for what was originally planned as a three-month mission. Opportunity found highly elevated levels of zinc in some of the rocks at the rim of the crater, suggesting that there was a hydrothermal system — warm water — running through the rocks at one time. In addition, veins of gypsum discovered at the crater were strong evidence that low temperature waters had at one time passed through those rocks.
