Opportunity (rover) a geographic feature named "Cape York". The Mars Reconnaissance Orbiter had detected phyllosilicates there, and the rover analyzed the rocks with its instruments to check this sighting on the ground. This structure was analyzed in depth until summer 2013. At May 2013 the rover was heading south to a hill named "Solander Point". "Opportunity"s total odometry as of June 27, 2016 (sol 4417) was , while the dust factor is 0.725. In December 2014, NASA reported that "Opportunity" was suffering from "amnesia" events in which the rover fails to write data, e.g. telemetry information, to non-volatile memory. The hardware failure
Opportunity (rover) early June 2018, a large global-scale dust storm developed and within a few days the rover's solar panels were not generating enough power to maintain communications, with last contact on June 10, 2018. NASA stated they did not expect to resume communication until after the global dust storm subsided, but the rover kept silent even after the storm ended in early-October, suggesting either a catastrophic failure or a layer of dust covered its solar panels. The team remains hopeful that a windy period between November 2018 and January 2019 may clear the dust from its solar panels, as has happened
