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 looks quiet today, but new research suggests the planet’s surface still carries the rhythm of a vanished companion.
