Water 20 km Below Mars Surface? What Study Shows And What It Means

Water is considered essential for life, and geological studies show the planet's surface had lakes, rivers and oceans more than 3 billion years ago.
A study released Monday using data from NASA's Mars InSight lander shows evidence of liquid water far below the surface of the fourth planet, advancing the search for life there and showing what might have happened to Mars' ancient oceans.
The lander, which has been on the Red Planet since 2018, measured seismic data over four years, examining how quakes shook the ground and determining what materials or substances were beneath the surface.
Based on that data, the researchers found liquid water was most likely present deep beneath the lander. Water is considered essential for life, and geological studies show the planet's surface had lakes, rivers and oceans more than 3 billion years ago.
