OPPORTUNITY UPDATE: Opportunity Celebrates 3,000 Martian Days of Operation on the Surface of Mars! - sols 2997-3001, June 29, 2012 - July 3, 2012:
Opportunity has now exceeded 3,000 sols, or Martian days, of operation on the surface of Mars! The rover is still exploring the north end of Cape York on the rim of Endeavour Crater.
On Sol 2997 (June 29, 2012), Opportunity completed an Alpha Particle X-ray Spectrometer (APXS) on the previously brushed target, called "Grasberg." On Sol 2998 (June 30, 2012), a 13-filter Panoramic Camera (Pancam) image was taken of the target, followed by a Rock Abrasion Tool (RAT) seek/scan and grind. The plan was to grind Grasberg to a depth of 1.5 mm, followed by a documentary Microscopic Imager (MI) mosaic. On Sol 2999 (July 1, 2012), the rover performed an atmospheric argon measurement with the APXS. On Sol 3000 (July 2, 2012), the rover collected only remote sensing science. On Sol 3001 (July 3, 2012), the RAT was used to brush the RAT grind tailings from the target Grasberg followed by more MI imaging and the placement of the APXS for a long integration. Opportunity continues to benefit from solar array dust cleaning events, which increase the daily energy production.
As of Sol 3001 (July 3, 2012), solar array energy production was 577 watt-hours with an atmospheric opacity (Tau) of 0.346 and an improved solar array dust factor of 0.705.
Total odometry is 21.43 miles (34,491.99 meters).
