Courtesy NASACan we expect to get more than 10 years out of our cars today? At best, they get listed as a "late model" vehicle in some classified ads. So how about our space cars?
This week the Mars rover Opportunity is marking its tenth year of rolling around the Red Planet. Not too shabby for something that was designed for just a quick three-month life span. It's partner rover, Spirit, seized up and got permanently stuck in sand three years ago. And now both vehicles are being overshadowed by Curiosity, the high-tech rover that just landed on Mars five months ago.
Like any older vehicle, Opportunity has its quirks. It gets around mostly in reverse these days because one of the front wheels doesn't turn well. Its robot arm needs some extra coaxing from operators to get jobs done. But it's still collecting samples and data. It total, it's logged 22 miles across the Martian terrain. Not too shabby for a late model rover.
Here's a link to NASA's webpage of photos and information that Opportunity has collected over the years.
