You can thank Martian “dust devils” for that.
Twelve years ago this week, NASA’s Mars Rover Opportunity landed on the Martian surface and started beaming back images of what the red planet was like, notes NASA’s blog. But perhaps even more impressive than the images it sent back is the fact that the Opportunity is still up and running on the dusty planet after 12 years. It was originally only supposed to work for 90 days.
