Mars rover Opportunity's vista includes long tracks
From a ridgeline viewpoint, NASA's Mars Exploration Rover Opportunity recently recorded a scene looking back over its own tracks made from nearly half a mile (more than 700 meters) of southbound driving.
Opportunity's panoramic camera (Pancam) recorded the component images on Aug. 15, 2014, from an elevated portion of the west rim of Endeavour Crater. A brief video places the scene into context with the rover's entire driving route of more than 25 miles (40 kilometers) since the mission's 2004 landing in the Meridiani Planum region of Mars.
The Opportunity mission has been investigating outcrops on the western rim of Endeavour Crater for three years. The crater spans 14 miles (22 kilometers) in diameter. During Opportunity's first decade on Mars and the 2004-to-2010 career of its twin, Spirit, NASA's Mars Exploration Rover Project yielded a range of findings proving wet environmental conditions on ancient Mars—some very acidic, others milder and more conducive to supporting life.
