Crater interior from Opportunity via Mars Express

This false-colour image of the interior of 'Endurance Crater' on Mars was collected on 4 August 2004 by NASA's Mars Exploration Rover Opportunity.

The image, taken with the Rover's panoramic camera, was relayed to Earth by ESA's Mars Express together with other scientific data.

Three separate frames, taken through red, green and blue filters, were combined to produce this colour image.
