Opportunity has arrived at Endeavour crater after a 1000-sol, 13.36 mile (21.5 kilometer) odyssey across the plains of Meridiani. On Sol 2681(Aug. 9, 2011), Opportunity drove 203 feet (62 meters), crossing the contact that delineates the geology of Cape York on the rim of the giant Endeavour crater. Now begins the next chapter in the surface exploration of Mars, the exploration of clay minerals, minerals that may hold the clues to an ancient, habitable environment in the early, wet Noachian epoch of Mars. The rover previously drove this week on Sol 2678 (Aug. 6, 2011), with a 246-foot (75-meter) drive in the run up to Endeavour. As of Sol 2681 (Aug. 9, 2011), solar array energy production was 374 watt-hours with an atmospheric opacity (Tau) of 1.12 and a solar array dust factor of 0.542. Total odometry is 20.81 miles (33,485.80 meters, or 33.49 kilometers).
