NASA’s Mars Reconnaissance Orbiter (MRO), has used its High Resolution Imaging Science Experiment (or HiRISE – and yes I know what you are thinking, and yes they did do that deliberately), to capture this amazing image of the Santa Maria Crater. Including the rover Opportunity sitting on the crater’s edge.

The astounding detail of the image also shows the tracks of the rover on the left hand side of the image.
The small blob indicated by the arrow is the rover itself.
The image was captured on the first of March which corresponds to Opportunity’s 2,524th Martian day of operation on the red planet.
