NASA's Mars rover Opportunity will back its way out of a crater it has spent four months exploring after reaching terrain that appears too treacherous to tread. Sitting at an incline inside "Endurance Crater" in Meridiani Planum, Opportunity has apparently reached in impasse. To the rover's right, slopes are too steep to pass, while on the left the terrain appears to contain sandy patches where Opportunity could bog down.
