Mars exploration isn't all about Curiosity and Opportunity rovers. NASA's Mars Reconnaissance Orbiter has snapped loads of beautiful hi-resolution images of the red planet's surface since 2006.

The spacecraft, which is operated by the University of Arizona, is equipped with a $40 million HiRISE (High Resolution Imaging Science Experiment) camera.

The device is the largest aperture reflecting telescope ever sent on a space mission, and is capable of taking 0.3 megapixel pictures.

Mars is known as the red planet, but the HiRISE images have been enhanced by 'false coloring,' which helps scientists track changes on the planet's surface.
