Opportunity is on the move again at the north end of Cape York on the rim of Endeavour Crater.

On Sols 3036 and 3037 (Aug. 8 and 9, 2012), the rover completed a set of Alpha Particle X-ray Spectrometer (APXS) measurements on a surface target, called "Rushall_1."

With the APXS integrations done, Opportunity swung the robotic arm out of the way so detailed Panoramic Camera (Pancam) images could be taken on Sol 3039 (Aug. 11, 2012).

On the next sol, the rover drove south with a 90-feet (27.5-meter) drive toward the small impact crater, called "Sao Rafael."

With "drive-by" imaging of the crater complete, Opportunity drove again on Sol 3042 (Aug. 14, 2012), with a 128-feet (39-meter) drive toward another small impact crater, called "Berrio."

The rover also had enough energy on that sol to collect an atmospheric argon measurement with the APXS.

As of Sol 3042 (Aug. 14, 2012), the solar array energy production was 545 watt-hours with an atmospheric opacity (Tau) of 0.564 and a solar array dust factor of 0.688.

Total odometry is 21.57 miles (34,705.88 meters).
