Researchers have found new evidence for a massive subsurface ocean on Mars, highlighting the possibility of microbial life ...

Mars might hold enough subsurface water to cover its surface in a global ocean between 0.62 to 1.24 miles (1 to 2 kilometers) ...

Seismic readings of the interior of Mars strongly suggest large quantities of water buried 6 to 12 miles underground.

Water once existed in abundance of at the surface of Mars. How much of that water has been stored in the planet's crust is still unclear, according to a new analysis.
