Mars may be drenched beneath its surface, with enough water hiding in the cracks of underground rocks to form a global ocean, new research suggests.

The findings, released on Monday, are based on seismic measurements from NASA’s Mars InSight lander, which detected more than 1,300 marsquakes before shutting down two years ago.
