What event in June 2018 marked the final period of Opportunity's mission?

Answer

A severe dust storm that choked the rover's solar panels

The operational lifespan of *Opportunity* significantly exceeded its initial projection, but its end was precipitated by extreme weather conditions on Mars. In June 2018, a massive, planet-engulfing dust storm descended upon the Martian surface. This storm severely limited the amount of solar energy reaching the rover's solar panels, leading to an inability to generate sufficient power to recharge its batteries. This power deprivation forced the rover into a precautionary hibernation mode from which it never recovered.
