Scientists find evidence for large underground reservoir of water on Mars

It is located in tiny cracks and pores in rock in the middle of the Martian crust, between 11.5km and 20km below the surface

Researchers have found evidence for a large underground reservoir of liquid water on Mars – enough to fill oceans on the planet’s surface.

Using data from Nasa’s Insight lander, the scientists estimated that the amount of groundwater could cover all of Mars to a depth of between one and two kilometres.
