About the time that life was taking hold on Earth, Mars not only had the ingredients for life as well, but long-lived lakes that could support it, new research from NASA’s Curiosity rover team shows.
Analysis of sediments and geologic features found in the rover’s Gale Crater landing site show that the basin periodically filled with water that lasted for hundreds or even thousands of years. Previously, the rover discovered evidence of an ancient shallow lake and streams.

“You have a deep hole, filled with water that is stable,” which indicates that Mars must have had a denser atmosphere at that point in its history than can be explained by current computer models, geologist John Grotzinger, with the California Institute of Technology, told Discovery News.
“It also means that other places were wet as well,” he added.
