NASA The White Cliffs of 'Rover'

This image was acquired by the High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA's Mars Reconnaissance Orbiter on April 18, 2017, at 14:04 local Mars time. It reminded the HiRISE team of the rugged and open terrain of a stark shore-line, perhaps of the British Isles. via NASA http://www.nasa.gov/image-feature/jpl/pia21760/the-white-cliffs-of-rover
