First traces of a planet wide underground water system on Mars have been discovered by the European Space Agency (ESA) Mars Express Mission. It has revealed the presence of interconnected underground lakes in ancient Mars approximately 3.5 billion years ago which were most likely connected to a Martian ocean, and the possibilities of minerals necessary for life. Lead author Francesco Salese said, “Early Mars was a watery world, but as the planet’s climate changed this water retreated below the surface to form pools and groundwater. We traced this water in our study, as its scale and role is a matter of debate, and we found the first geological evidence of a planet-wide groundwater system on Mars.” Co-author Gian Gabriele Ori said, “These lakes would have existed around 3.5 bn years ago, so may have been contemporaries of a Martian ocean.”Scientists testing a NASA robot have also made a recent discovery that could be helpful in proving life on Mars.
