The Opportunity rover is still gathering scientific observations and reporting back to Earth after being on Mars for 12 years - nearly 50 times its designed lifespan
On January 3, 2016 (Sol 4246), Opportunity went through the winter solstice on Mars with already improved solar insolation, with the rover producing 449 watt-hours from its solar panels.[144] On January 25, 2016, Opportunity had marked twelve years since landing on Mars and continued its scientific investigation of Marathon Valley.[145@Curionic
