Description
This view of the interior slope and rim of "Endurance Crater" comes from the navigation camera on NASA's Mars Exploration Rover Opportunity with an assist from the European Space Agency's Mars Express orbiter. Opportunity took the three frames that make up this image on the rover's 188th martian day (Aug. 4, 2004), before transmitting this and other data to Mars Express. The orbiter then relayed the data to Earth. Rover wheel tracks are visible in the foreground.
