Clays in the history of Mars

Article Abstract:

The stream of revelations from Mars claims the discovery of clays in ancient terrains, which help to fill in the picture of past existence of liquid water on the surface of the planet. The three orbiting spacecraft and two rovers that continue to return data have great deal of evidence that abundant surface water existed in Mars.
