Awesome! In short, ground-penetrating radar on Mars Express discovered a presumably very salty and very cold lake about a mile beneath the surface near the South Pole on Mars. I imagine it’d be extremely difficult to dig that deep, but maybe fossils and life signs would make it near the surface, giving us a good place to look, for a future mission.

Wow, fantastic – thanks for posting. It’s amazing how the [Earth analogue](http://advances.sciencemag.org/content/4/4/eaar4353) (in Canada) was just described in the literature a couple of months ago…apparently a case of planetary and Earth discoveries influencing each other, on how best to interpret certain data signatures.

Cool. But if we can figure out how to build probes that can dig, I’d rather we visit Europa and try to get at that underground ocean.

There’s life in there! I can feel it in my gut!! 🙂
