This map shows the traverse of NASA’s Mars Exploration Rover Opportunity through the rover’s 205th martian day, or sol (Aug. 21, 2004). The background image is from the rover’s descent imaging camera. Images inset along the route are from Opportunity’s navigation camera. Opportunity began its exploration inside “Eagle” crater near the left edge of the map. Following completion of its study of the outcrop there, it traversed eastward to a small crater (“Fram” crater) before driving southeastward to the rim of “Endurance” crater. After a survey partly around the south rim of Endurance crater, Opportunity drove inside the southwest rim of Endurance crater and began a systematic study of outcrops exposed on the crater’s inner slope.
