Opportunity Status for sol 2080-2090: On Sol 2086 (Dec. 6, 2009), the rover backed away and then drove about 5 meters (16 feet) around Marquette Island to image other parts of the rock.
On Sol 2089 (Dec. 9, 2009), Opportunity performed a 5-meter (16-foot) approach to the rock to position the rover for an in-situ (contact) study of a different part of the rock than it had touched earlier.
On the next sol, the robotic arm (instrument deployment device, or IDD) collected a mosaic of images by the microscopic imager (MI) and then placed the alpha particle X-ray spectrometer (APXS) on a new location on the rock for a long integration.
The elevation mirror shroud of the miniature thermal emission spectrometer (Mini-TES) is being opened when appropriate with the expectation of eventual dust cleaning.
No dust cleaning of the Mini-TES mirror has been noted yet.
As of Sol 2090 (Dec. 10, 2009), Opportunity's solar-array energy production is 359 watt-hours, with an atmospheric opacity (tau) of 0.498 and a dust factor of 0.529. Total odometry is 18,917.41 meters (11.75 miles).
