Opportunity Mars Rover Marks 12 Years on Red Planet

Opportunity landed on Mars 12 years ago Sunday (Jan. 24), a few weeks after its twin, Spirit, hit the red dirt. Spirit and Opportunity were originally supposed to explore for just 90 days, but both rovers far outlasted their warranties. Spirit stopped communicating with Earth in 2010 and was declared dead a year later, and Opportunity is still going strong today.
