NASA annouces that liquid water flows on Mars (10 images)

NASA confirmed that liquid water flows on the surface of Mars, at NASA headquarters in Washington, D.C. on September 28, 2015.



These dark, narrow, 100 meter-long streaks called recurring slope lineae flowing downhill on Mars are inferred to have been formed by contemporary flowing water. Recently, planetary scientists detected hydrated salts on these slopes at Hale crater, corroborating their original hypothesis that the streaks are indeed formed by liquid water. The blue color seen upslope of the dark streaks are thought not to be related to their formation, but instead are from the presence of the mineral pyroxene.

Dark narrow streaks called recurring slope lineae emanating out of the walls of Garni crater on Mars. The dark streaks here are up to few hundred meters in length. They are hypothesized to be formed by flow of briny liquid water on Mars.

John M. Grunsfeld, Associate Administrator for the Science Mission Directorate at NASA, speaks at a press conference announcing that NASA has confirmed that liquid water flows on the surface of Mars, at NASA headquarters in Washington, D.C. on September 28, 2015. NASA's Mars Reconnaissance Orbiter (MRO) provided the strongest evidence yet that liquid water flows intermittently on present-day Mars which opens up the idea that life of some kind may exist now or in the past on Mars.
