Opportunity Rover Marks 10 Year Anniversary on Mars

Mission was supposed to last 90 Martian days


Opportunity is marking its 10th anniversary on Mars with a little bit of well-earned recognition. The NASA rover was eclipsed in popularity by its much more Wall-E counterpart, Curiosity, when that high-rolling rover landed nine years later.

Curiosity was a superstar. This was a sleek, brawny geochemistry lab, the biggest robot ever landed on another planet. And its Twitter feed is consistently adorable.
