Orbiter Examines Clues to Possible Water Flows on Mars

February 11, 2014

0 Comments

Using images from NASA’s Mars Reconnaissance Orbiter, several new studies examine recurring slope lineae on Mars and possible water flows. NASA spacecraft orbiting Mars have returned clues for understanding seasonal features that are the strongest indication of possible liquid water that may exist today on the Red Planet. The features are dark, finger-like markings that […]
