How much water did Mars have in its ancient past and when did it disappear? This is what a recent study published in Geophysical Research Letters hopes to address as an international team of ...

Mars's water disappeared somewhere, but scientists have been disagreeing for years about where exactly it went.

Liquid water once shaped the Martian landscape dramatically, carving valleys, filling lakes, and forming vast oceans. Billions of years ago, during Mars' early days known as the Noachian and Hesperian ...

Scientists have found seismic clues that suggest liquid water may be hiding beneath Mars' surface. By listening to the echoes of "marsquakes" — seismic waves rippling through Mars' crust — researchers ...

Mars was once rich with flowing water. Today, it's a cold, dusty desert marked by dried riverbeds and empty lake basins. Traces of ancient streams wind across its surface, hinting at a time when water ...

Map showing water percolation rates on Mars billions of years ago according to research from UT Jackson School of Geosciences. Surface water sinking through the Martian soil took between 50 years ...

Was Mars a friendly planet for water, even life, in its ancient past? Huge channel networks run across its surface. Rocks show signs of water immersion. Yet pictures sent back from NASA's Curiosity ...

This finding suggests that Mars has been losing water year-round for billions of years, rather than just during specific ...

Mars’ water disappeared somewhere, but scientists have been disagreeing for years about where exactly it went. Data from rovers like Perseverance and Curiosity, along with orbiting satellites such as ...
