Opportunity today passed the Martian surface longevity record set by Viking 1 (six years and 116 days). As UniverseToday reminds us, orbiters have lasted longer; Mars Global Surveyor operated for more than 9 years and Mars Odyssey is on track to beat that record late this year. Opportunity’s sibling, Spirit , has not been heard from since March 22, but if she wakes from hibernation and resumes communication, then she will claim the Martian surface longevity record.

The above photo shows tracks left by Opportunity as it traversed the martian landscape.
