Evidence of water on Mars increases possibility of life Houston Chronicle

Neighboring Mars may look dry as a bone, but experts are finding evidence of life-sustaining water hidden below the planet’s rugged terrain. The quantities discovered so far by instruments aboard NASA’s $300 million Mars Odyssey mission equal twice the volume of Lake Michigan. Suspected for more than three decades, the watery findings compiled by the Odyssey after reaching its destination a year ago are a signpost of life on the Red Planet.
