Opportunity Status at end of sol 86
Opportunity's 86th sol, which ended at 4:53 p.m. PDT on April 21, was another record-breaker! A nearly two-and-a-half hour grind produced an impressive 7.2 millimeter (about 0.28 inches) hole in the rock called "Pilbara."
The plan for the rest of the sol called for placing the alpha particle X-ray spectrometer on the new impression to determine the elemental composition of the exposed area. It was determined, however, that the rover position would not allow for a safe integration of the instrument. Rover planners amended the plan for the sol so the rover would back up and reposition itself for a safe placement of the spectrometer after the rock abrasion tool completed the grind.
On sol 87 the rover will analyze the rock abrasion tool hole with the alpha particle X-ray and Moessbauer spectrometers.
