Today NASA has made the announcement that  water flows on Mars. These new findings from NASA's Mars Reconnaissance Orbiter provide strong evidence that liquid water flows intermittently on the planet in present-day. 

On MRO, NASA has used an imaging spectrometer which has allowed researchers to detect signatures of hydrated minerals on slopes where streaks appear on Mars. They darken and appear to flow down these slopes during the warm seasons and fade in the cooler seasons. They appear in several different locations on the Red Giant when temperatures are above minus 23 Celisius and disappear at colder times. 

 “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.”
