“Although we still can’t say that life could have existed in this environment it is now certain that there was water on Mars ”said Steve Squyres one of the scientists working on the Mars mission(任务)．The evidence comes from pictures and chemical readings taken by Opportunity．It includes marks on rocks like those caused by following water on Earth and salty chemicals like those found in dried-out sea-beds．Scientists said the new evidence proved beyond doubt that water has existed on Mars．But it is still unknown whether the water was like an ocean or just ice．
While Opportunity has not found any signs of life the presence of water means life is possible．“In everything we know about life on Earth there is no example without liquid water ”Squyres said．“So water is important for the search for life on Mars．”
