Difficult Terrain for Opportunity
Wheel tracks from NASA's Mars Exploration Rover Opportunity show where the rover struggled for traction while driving away from "Wopmay" rock inside "Endurance Crater." The rover looked back for this view from its navigation camera on its 272nd martian day (Oct. 29, 2004).
