This image uses a view from the navigation camera on NASA's Mars Exploration Rover Opportunity to show context for a horizon shot by the rover's narrower-angle panoramic camera. The navigation camera exposures were taken during the 2,220th Martian day, or sol, of Opportunity's mission on Mars (April 22, 2010).

The horizon view from the panoramic camera, at PIA13081 and PIA13080, includes a portion of the rim of Endeavour crater, the rover's destination in a multi-year traverse along the sandy Martian landscape. Opportunity began a marathon from Victoria to Endeavour in September 2008 after spending two years exploring Victoria.
