Pakistan, May 13 -- In a major development for space exploration, scientists have found strong signs of liquid water beneath the surface of Mars. According to an international research team led by Chinese scientists, a possible reservoir of liquid water may exist just 5 to 8 kilometers below the planet's surface-much closer than earlier estimates suggested.

The findings are based on seismic data collected by NASA's InSight lander, which studied Mars from 2018 to 2022. Instead of moving across the surface like a rover, the lander was designed to "listen" to underground activity, recording more than a thousand marsquakes during its mission. This valuable data helped scientists analyze how seismic waves traveled through different layers of ...
