As it enters its tenth year on Mars, Opportunity will continue studying the chemical makeup and pinning down the ages of several interesting rocks at its location for several more months before adding more mileage to the 22 miles it has logged since landing.
As for the hunt for carbon, all eyes are on Curiosity, set to drive later this year to the base of a mountain where rock layers containing clay minerals have been detected.
Callas, the JPL project manager, said Curiosity has a long way to go to catch up with Opportunity, which has nearly a decade head start on the Martian surface.
“Mars is big enough for more than two rovers to explore,” he said.
