Water on Mars: Flowing salt water discovered on the Red Planet
NASA announced today that the Mars Reconnaissance Orbiter has revealed possible evidence of flowing water during the warmest months on Mars.
Dark spines of what scientists believe may be salt water has been repeatedly seen flowing down the steep slopes of middle latitudes of Mars' southern hemisphere.
"The best explanation for these observations so far is the flow of briny water," said Alfred McEwen of the University of Arizona.
