In one of the most exciting discoveries of our generation, a reservoir of briny water has been discovered by the European Space Agency’s Mars Express under the surface of Mars. This shallow subglacial lake is 2.4 miles wide and may include still flowing water.
While recent discoveries appear to show the existence of large amounts of surface water in the distinct past on the planet, this new paper in Science suggests water may still be there. It was conclusion reached with the help of the Mars Advanced Radar for Subsurface and Ionospheric Sounding or MARSIS project. Imagine even that prospect for possible life or even supporting a Mars colony.
