The Mars Exploration Rover Opportunity arrived at the red planet in January 2004. Looking back at the rover’s landing site, the Mars Reconnaissance Orbiter image (inset) reveals Opportunity’s lander within Mars’ Eagle Crater. Over the past 13 years, the rover has traveled over 25 miles (40 kilometers), returned more than 180,000 images and found evidence for ancient environments with liquid water.
Since late 2014, Opportunity has been studying “Cape Tribulation”, an area at the southern end of Mars’ Endeavour Crater. Taken by the rover, the panoramic image reveals “Rocheport” (arrows), a ridge near “Cape Tribulation”. Scientists believe the ridge’s crest line may have been carved by water or ice or wind. In April 2017, the rover started traveling south to "Perseverance Valley."
