Life on Mars? Water detected in 12-mile lake under surface of planetary neighbor. The presence of liquid water under the Martian polar ice caps has long been suspected but not seen, until now, scientists said. The discovery, which was seen in radar data from an orbiting European spacecraft, raises the possibility of finding life on the red planet. Ref. USAToday.
Overflowing crater lakes carved canyons across Mars. Today, most of the water on Mars is locked away in frozen ice caps. But billions of years ago it flowed freely across the surface, forming rushing rivers that emptied into craters, forming lakes and seas. New research has found evidence that sometimes the lakes would take on so much water that they overflowed and burst from the sides of their basins, creating catastrophic floods that carved canyons very rapidly, perhaps in a matter of weeks.

Rivers raged on Mars late into its history. Scientists have catalogued these rivers to conclude that significant river runoff persisted on Mars later into its history than previously thought. According to the study, the runoff was intense -- rivers on Mars were wider than those on Earth today -- and occurred at hundreds of locations on the red planet. Source 1m.
