NASA rover, Opportunity, a veteran of surviving the harsh Martian landscape has completed 12 years on Mars.
It’s now that most believed would limit its lifespan to months as it is showing its age. Opportunity moves at a turtle’s pace, and maybe slower now in its old age, but it keeps moving. Its joints ache and lock, two of its scientific instruments no longer work, and it suffers bouts of amnesia caused by faulty flash memory. In the past two years, it broke the record for the longest distance traveled on another planet.
Opportunity’s sibling, Spirit, landed weeks earlier and lasted six years.
