View Down 'Perseverance Valley' After Entry at Top

This mosaic scene combining five images from the navigation camera (Navcam) on NASA's Mars Exploration Rover Opportunity shows a view from inside the upper end of "Perseverance Valley" on the inner slope of Endeavour Crater's western rim. The valley is the main destination for the current two-year extension of the 13-year-old Opportunity mission on Mars. It was likely carved long ago by a fluid, such as water, water-lubricated debris or wind.
