Opportunity is located at the feature called 'Spirit Mount' on the rim of Endeavour Crater, the first science waypoint of the 10th extended mission.
The rover is by the surface featured called 'Gasconade,' conducting detailed in-situ (contact) investigations with the robotic arm. On Sol 4515 (Oct. 5, 2016), Opportunity used the robotic arm to collect a Microscopic Imager (MI) mosaic of the target, then place the Alpha Particle X-ray Spectrometer (APXS) on an offset from Gasconade for a multi-hour integration.
On the next sol, the rover performed a small, 11-degree turn to set up for another surface target. On the sol after that, Opportunity collected a MI mosaic of the new target and then placed the APXS.
Over the coming sols, the rover collected a Navigation Camera (Navcam) panorama of Spirit Mound before backing up just over a meter on Sol 4520 (Oct. 10, 2016), to image the targets in the robotic arm work volume.
Then on Sol 4521 (Oct. 11, 2016), the rover performed a 6-foot (1.9-meter) approach to a new set of surface targets. A solar array dust cleaning event happened on Sol 4517 (Oct. 7, 2016), improving the rover's daily energy production.
As of Sol 4521 (Oct. 11, 2016), the solar array energy production is 507 watt-hours with an atmospheric opacity (Tau) of 0.907 and an improved solar array dust factor of 0.764.
Total odometry is 26.99 miles (43.44 kilometers).
