New research based on seismic measurements from NASA's Mars InSight lander indicates that Mars may be drenched beneath its surface, with enough water hiding in the cracks of underground rocks to potentially form a global ocean. The findings, released recently, are derived from the detection of over 1,300 marsquakes by the InSight lander before it ceased operations two years ago.
The water, believed to be located between seven to twelve miles (11.5 to 20 kilometers) down in the Martian crust, is speculated to have seeped from the surface billions of years ago when Mars likely had rivers, lakes, and even oceans. However, the presence of water inside Mars does not necessarily imply the existence of life, according to the lead scientist.
