MRO Provides New Clues About Water On Mars

New images from NASA’s Mars Reconnaissance Orbiter show finger-like markings that stream down Martian slopes when temperatures change, which would most likely occur if liquid water was present. Scientists are calling these dark flows “recurring slope lineae” and they have found 13 confirmed sites. They say they’re stronger when it’s warmer and less significant when it’s cooler. Sounds like water right? Either of the explanations that scientists have come up could suggest the presence of liquid water. Best guess so far? These features occur from the flow of near-surface water in which salt helps to keep the water from freezing.
