The rover continues to explore the region called 'Cook Haven.' The rover has turned its attention to other rocks within this area. On Sol 3568 (Feb. 5, 2014), Opportunity lifted her robotic arm so 13-filter Panoramic Camera (Pancam) images of the surface target, called 'Green Island' could be collected, along with some Navigation (Navcam) images. On the next sol, the rover used the Rock Abrasion Tool (RAT) to brush a spot on Green Island and followed that with a Microscopic Imager (MI) mosaic and a placement of the Alpha Particle X-ray Spectrometer (APXS).
On Sol 3571 (Feb. 8, 2014), the rover collected a 13-filter Pancam image of the brushed spot on Green Island before bumping about 9.8 feet (3 meters) to a new rock target, called 'Stuart Island.' Opportunity began the in-situ (contact) investigation of Stuart Island on Sol 3573 (Feb. 10, 2014), with a MI mosaic and APXS placement for an overnight integration. The rover repeated this again on the next sol with more MI mosaics, but with an offset placement of the APXS. Continuing the campaign on Sol 3575 (Feb. 12, 2014), Opportunity collected more MI mosaics and performed a third offset of the APXS.
As of Sol 3575 (Feb. 12, 2014), the solar array energy production was 387 watt-hours with an atmospheric opacity (Tau) of 0.548 and a solar array dust factor of 0.610.
Total odometry is 24.07 miles (38.74 kilometers).
