New evidence of liquid water far below the surface on Mars is giving insight into what might have happened to Mars’ ancient oceans. :: NASA/JPL-Caltech The recently released study uses data from ...

Enough water to cover the surface of Mars has been discovered within the crust of the Red Planet by NASA's InSight mission. The ocean is buried between one and two kilometers (0.62 and 1.24 miles) ...

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 ...

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 ...

More than 3 billion years ago, Mars was warm, wet, and had an atmosphere that could have supported life. This artist's rendering shows what the planet may have looked like with global oceans based on ...

Data has revealed evidence of an underground reservoir of water deep beneath the surface of Mars. Scientists say the water is believed to be seven miles to 12 miles down in the Martian crust. The ...

Exotically pitted “Swiss-cheese” terrain made of carbon dioxide (dry ice) overlies the topmost layer of water ice in Mars’ South Polar Massive Carbon Dioxide Ice Deposit. Image is about 1 kilometer ...

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 ...

Scientists have now identified water frost on the summits of several large Martian volcanoes, indicating potential habitable zones for future missions to the Red Planet. This discovery, led by Dr.

Rain will probably never fall on Mars’ giant volcano, Olympus Mons (our condolences to the MMC). But a glittering swath of frost covers the Martian mountaintop on chilly mornings, according to new ...
