By using the Mars rovers as well as high-tech orbital data, scientists have been able to make significant progress in their search for evidence of water on Mars. Water is key to life, hence the intense search, but previously it was difficult to say whether water existed in any significant amount on the Martian planet. Now, Caltech scientists believe that they have found evidence of a river delta that flowed into a large body of water on the planet. The Aeolis Riviera is the strongest evidence thus far of a large amount of water on Mars.

 

The Caltech team utilized high-resolution images from NASA’s Mars Reconnaissance Orbiter’s High-Resolution Imaging Science Experiment (HiRISE) camera to examine the surface of the planet closely.
