NASA's Mars Exploration Rovers (MER) are an ongoing robotic space mission involving two rovers, Spirit and Opportunity, exploring the planet Mars. The missions began in 2004 with the arrival of the two rovers—Spirit and Opportunity—on the Martian surface. It continues to this day with Opportunity still in operation over a decade later.
