By studying seismic waves, researchers have found a layer deep beneath the surface of Mars that could contain enough liquid water to flood the planet with an ocean thousands of feet deep.

Now a recent study published in the journal Proceedings of the National Academy of Sciences reveals that there is a large amount of groundwater on Mars. To find it, just dig beneath the surface.
