NASA announced the completion of the Mars Exploration Rover (MER) Opportunity’s mission after a final attempt to command the rover on 12 February 2019. Opportunity last communicated with Earth on 10 June 2018, as a global dust storm blanketed the solar-powered rover's location on Mars. Opportunity landed at Meridiani Planum on Mars 25 January 2004. The rover had an initial goal of driving 600 meters and operating for 90 Martian days (sols). Instead, Opportunity operated over 14 years, and traveled over 45 kilometers.
