Water on Mars? Scientists See Possibility of Salty Water in Martian 'Seasonal Flows'

A team of scientists, led by Alfred S. McEwan of the Lunar and Planetary Laboratory, University of Arizona, Tucson, may have identified the tell-tale signs of “seasonal flows” (small channels attributable to downhill water movements) on certain Martian slopes. The potentially game-changing discovery, which was enabled by an analysis performed by an undergraduate student, has got the astronomy, planetary and astrobiology science communities rather excited.
