NASA's Mars orbiter finds water flowed on Red Planet longer than thought
Caltech scientists studying data from NASA`s Mars Reconnaissance Orbiter found signs of liquid water on the Red Planet as recently as 2 billion to 2.5 billion years ago, meaning water flowed there about a billion years longer than previous estimates.

Mars absorbed water on its surface like a sponge: Study
Previous research has suggested that the majority of the water was lost to space as a result of the collapse of the planet’s magnetic field, when it was either swept away by high intensity solar winds or locked up as sub-surface ice. However, these theories do not explain where all of the water has gone.
