Mars flooding - The discovery shows that a major underground channel generated by an ancient mega-flood is twice as deep as thought, and sheds light on how water shaped the surface of Mars, scientists added. Radar scans of Mars have revealed the first 3D look at water-carved channels buried beneath the Red Planet's surface, researchers say.

Mars today is cold and dry, with most of its water locked in polar ice caps, and researchers think its surface has been largely barren for the past 2.5 billion years. However, channels crisscrossing its surface hint that waters once flooded the Red Planet's surface.
The largest of the channels engraved into Mars within the past 500 million years belong to the 600-mile-long (1,000 kilometer) Marte Vallis system. Probing Marte Vallis could offer hints on a time otherwise thought of as cold and dry. [The Search for Water on Mars (Photos)]
