NASA Confirms Evidence That Liquid Water Flows on Today’s Mars

In Technology, The Enviroment by Dusty Croghan

According to NASA, new findings from NASA’s Mars Reconnaissance Orbiter (MRO) provide the strongest evidence yet that liquid water flows intermittently on present-day Mars. Dark narrow streaks called recurring slope lineae emanating out of the walls of Garni crater on Mars. The dark streaks are up to few hundred meters in length. They are hypothesized to be formed by flow of briny liquid water on Mars. According to researchers, almost all water on Mars today exists as ice, though it also exists in small quantities as vapor in the atmosphere.

“Our quest on Mars has been to ‘follow the water,’ in our search for life in the universe, and now we have convincing science that validates what we’ve long suspected,” said John Grunsfeld, astronaut and associate administrator of NASA’s Science Mission Directorate in Washington. “This is a significant development, as it appears to confirm that water — albeit briny — is flowing today on the surface of Mars.”

“The ability of MRO to observe for multiple Mars years with a payload able to see the fine detail of these features has enabled findings such as these: first identifying the puzzling seasonal streaks and now making a big step towards explaining what they are,” said Rich Zurek, MRO project scientist at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California.
