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. The image is produced by draping an orthorectified (RED) image (ESP_031059_1685) on a Digital Terrain Model (DTM) of the same site produced by High Resolution Imaging Science Experiment (University of Arizona). Vertical exaggeration is 1.5.  (Credits: NASA/JPL/University of Arizona)

NASA — NASA today and yesterday have released images confirming the existence of water on Mars. Streaks caused by running water during the planet’s spring and summer seasons have been observed and confirmed by the existence of minerals deposited by the running water.
This monumental discovery makes the cold and once believed arid planet a big step closer to being able to support life and stirs interest in a manned exploration of the planet.
Astronaut and associate administrator of NASA’s Science Mission Directorate in Washington John Grunsfeld said, “ 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. This is a significant development, as it appears to confirm water — albeit briny — is flowing today on the surface of Mars.”
Possibility of water was first noticed by a undergraduate student at the University of Arizona in 2010. Lujendra Ojha who was studying high resolution images from NASA’s MRO.(the Mars Reconnaissance Orbiter which has been up since 2006). Ojha is now at Georgia Tech in Atlanta and was the lead author on the report that was released yesterday
.NASA’s lead scientist on the Mars Exploration program in Washington said it had taken several years to solve the mystery and “now we know there is liquid water on the surface of this cold desert planet. The Mars Exploration program leader added significantly added “ It seems that the more we study Mars the more we learn how life could be supported and where there are reserves to support life in the future.”

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. The image is produced by draping an orthorectified (Infrared-Red-Blue/Green(IRB)) false color image (ESP_030570_1440) on a Digital Terrain Model (DTM) of the same site produced by High Resolution Imaging Science Experiment (University of Arizona).
