NASA's Curiosity rover, in its mission to find earth-like life on Mars, has found geological evidence of dried river beds, giving an indication of a once flooded water body on the Red Planet.
The latest images taken by Curiosity were disclosed on Thursday. The newly-beamed photographs showed shingles in circular structures that may have been shaped by long-distance streams.
"The shapes tell you they were transported and the sizes tell you they couldn't be transported by wind. They were transported by water flow," said PSI senior scientist Rebecca Williams, a Curiosity mission science co-investigator.
Curiosity Rover, which has been on its mission since Aug 6, also examined two protrusions on the land named as 'Link' and 'Hottah', which scientists determined were likely formed by deep waters.
NASA landed Curiosity rover in Mars after early evidence hinted the presence of water on the planet.
"Certainly flowing water is a place where microorganisms could have lived. This particular kind of rock may or may not be a good place to preserve those components that we associate with a habitable environment," said lead scientist John Grotzinger at the California Institute of Technology.
NASA's Curiosity rover is on a two-year mission to find evidence of life on Mars. Curiosity are yet to determine the chemical makeup of the rocks formations discovered earlier in September.
