Data suggests liquid water ocean exists under Mars

Scientists have found strong evidence of a vast underground reservoir of liquid water on Mars, potentially reshaping our understanding of the planet. This discovery suggests a hidden water source deep within the Martian crust. Using seismic data from NASA's InSight mission, researchers identified a layer between 5.4 and 8 kilometers below the surface where seismic waves slowed down, indicating the presence of liquid water. This "aquifer layer" could hold enough water to cover the planet in a global ocean. This finding, based on marsquake and meteorite impact data, supports the theory that much of Mars' "missing" water is trapped underground. This discovery raises the possibility of past or present life and could be a resource for future human exploration.
