Planet-Wacing Night on Mars: The 2018 Global Dust Storm That Silenced Opportunity
A 2018 planet-wide Martian dust storm blocked sunlight for months, drenching Opportunity’s solar panels and ending its 15-year mission after last contact on June 10, 2018; NASA formally closed the rover’s file in February 2019 with a final odometer of 45.16 km. The storm’s opacity peaked around tau 10.8 at Opportunity, illustrating how even sun-powered rovers can be overwhelmed by Mars’s weather, while Curiosity remained online on plutonium power. The event spurred studies of atmospheric dynamics and Mars-wide water loss, and it helped shift mission design away from sun-dependent surface explorations.,
