Opportunity is still positioned at the target called "Chester Lake" at Cape York on the rim of Endeavour crater. The rover continues with the in-situ (contact) science investigation of the surface rock called "Salisbury 1."

On Sol 2726 (Sept. 24, 2011), the previously ground Rock Abrasion Tool (RAT) hole was re-brushed to remove excessive tailings. Microscopic Imager (MI) images were collected confirming the successful brushing. The Alpha Particle X-ray Spectrometer (APXS) was placed down on the target for a post-brush integration.

On Sol 2729 (Sept. 27, 2011), the APXS was retracted from the RAT hole, a Pancam 13-filter image set was taken. Then, along with more MI images, a test of the MI poker was performed.

The test results indicate normal operation of the poker. The Moessbauer (MB) spectrometer was placed down in the hole for a multi-sol integration.

As of Sol 2729 (Sept. 27, 2011), solar array energy production was 313 watt-hours with an atmospheric opacity (Tau) of 0.882 and a solar array dust factor of 0.514.

Total odometry is 20.86 miles (33,574.75 meters, or 33.58 kilometers).

Opportunity Continues to Study 'Chester Lake' Rock Outcrop
Pasadena CA (JPL) Sep 27, 2011
Opportunity is still positioned at the target called "Chester Lake" at Cape York on the rim of Endeavour crater. On Sol 2717 (Sept. 15, 2011), the rover successfully brushed the surface target, "Salisbury 1," followed by a mosaic of images collected by the Microscopic Imager (MI) and then a placement of the Alpha Particle X-ray Spectrometer (APXS) for an overnight integration.
