In this image, north is up. The southern end of the solid blue line indicates the rover's position after a drive on Sol 3926, the 3,926th Martian day of Opportunity's work on Mars (Feb. 9, 2015). The rover team plans to drive Opportunity near or into "Spirit of St. Louis Crater" before the rover enters Marathon Valley. This area is all part of the western rim of Endeavour Crater.
Opportunity reached the Sol 3881 location near the top of the map on Dec. 24, 2015. A map showing wider context of Opportunity's route from its January 2004 landing in Eagle Crater to Endeavour Crater is at PIA18404. A view from the Sol 3893 location at the summit of "Cape Tribulation," taken the following sol, is at PIA19109. The traverse from that location to the Sol 3926 location covered about 440 yards (400 meters).
The rover's traverse shown here has been mapped by Tim Parker of NASA's Jet Propulsion Laboratory, Pasadena, California, onto an image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.
Opportunity completed its three-month prime mission in April 2004 and has continued operations in bonus extended missions. It has found several types of evidence of ancient environments with abundant liquid water. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, built and operates Opportunity and manages the Mars Exploration Rover Project and the Mars Reconnaissance Orbiter for the NASA Science Mission Directorate, Washington. The University of Arizona, Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp. of Boulder, Colorado.
