NASA's Mars Exploration Rover Opportunity looks through its navigation camera as it leaves the home it has known for over 200 sols. The rover spent 181 sols inside "Endurance Crater," furthering our knowledge of ancient water on Mars. After that challenging work, it spent 25 sols investigating the heat shield that protected it on its way through the martian atmosphere and the nearby meteorite that was the first discovered on another planet. Opportunity is saying 'so long' and heading south for a small crater referred to as "Argo." This image was taken on the rover's 359th sol on Mars (January 26, 2005).
