Astronomers have found compelling evidence that there is a huge reservoir of liquid water buried a mile under the ice near the south pole on Mars.
Radar measurements taken from the European Space Agency’s Mars Express orbiter spotted the 12 mile-wide stretch of water at the base of a thick slab of polar ice in a region known as Planum Australe.
It is the first time that researchers have identified a stable body of liquid water on the red planet. The finding raises the likelihood that any microbial life that arose on Mars may continue to eke out a rather bleak existence deep beneath the surface.
This could be a great target to practice for the farther out (and more difficult) missions to Europa and other ice planets/moons with liquid seas under their ice crusts
