Data from the late Mars InSight lander continues to pay dividends, with the latest findings suggesting that there is abundant liquid water in the mid-crust of Mars (about 7 to 12 miles deep).

The discovery comes via a trio of researchers from the University of California San Diego and UC Berkeley, who said in a paper published yesterday that they have been examining seismological data from InSight to learn more about Mars' water cycle.
"A middle crust composed of fractured igneous rocks saturated with liquid water best explains the existing data," the researchers wrote. "Our results have implications for understanding the Martian water cycle, determining the fates of past surface waters, searching for past or extant life, and assessing in situ resource use for future missions."
We have long suspected that water existed on Mars, and recent scientific missions to the Red Planet have repeatedly found evidence that our planetary neighbor once harbored rivers, lakes and oceans on its surface.
