A third of Mars was once

covered by ocean: Study

Paris: A huge, potentially life-giving sea likely covered more than a third of Mars some 3.5 billion years ago, according to a study released on Sunday.

        Spread over an area the size of the Atlantic Ocean, it would have straddled the north pole and contained the equivalent of a tenth of the water on Earth. For decades, scientists have argued as to whether the red Planet once harboured bodies of water big enough to help nourish a true hydrological cycle marked by evaporation and rainfall.

       Recent evidence suggests as much, but doubts remained. To dig deeper. Gaetano Di Achilie and Brian Hynek of the University of Colorodo in Boulder sifted through huge stores of images collected by NASA's Mars Orbiter laser Al timeter (MOLA) in the late 1990s and other more recent European and US satellite based monitoring systems.

       The data was not new, but the researchers were the first to link up all available informatioon Mars' terrain into a single computer driven model.
