Opportunity has exceeded over 35 kilometers (21.75 miles) of odometry!

The rover is moving south along the inboard edge of Cape York on the rim of Endeavour Crater surveying exposed outcrop in search of phyllosilicate clay minerals that have been detected from orbit.

On Sol 3051 (Aug. 23, 2012), Opportunity continued to move about 98 feet (30 meters) south along the inboard edge of Cape York, imaging the outcrop to the west with both Panoramic Camera (Pancam) and Navigation Camera (Navcam). On Sol 3053 (Aug. 25, 2012), the rover drove further south with more of an inboard bias to be closer to the outcrop. Again, more detailed Pancam and Navcam surveys were performed. On Sol 3055 (Aug. 27, 2012), the Rock Abrasion Tool (RAT) on the end of the robotic arm was imaged to re-confirm the available bit for future grinding and the Alpha Particle X-ray Spectrometer (APXS) collected a measurement of atmospheric argon.

On Sol 3056 (Aug. 28, 2012), Opportunity headed almost due west in a direct approach to some exciting outcrop units. With that drive, the rover passed 35 kilometers of odometry. Not bad for a vehicle designed for only about 1 mile (1 kilometer) of distance and 90 sols (days) of lifetime.

As of Sol 3056 (Aug. 28, 2012), the solar array energy production was 568 watt-hours with an atmospheric opacity (Tau) of 0.570 and a solar array dust factor of 0.684.

Total odometry is 21.76 miles (35,017.33 meters).
