Space agency scientists have begun testing four new skills included in flight software that has been uploaded to the rovers' onboard computers.
The two American rovers, Spirit and Opportunity, are approaching their third year on the Martian surface.
One of the new capabilities is designed to allow the rovers to make "intelligent" decisions in the study of Martian clouds and dust devils.

Another novel skill, called "visual target tracking", enables a rover to keep recognising a particular landscape feature as the rover moves.
***
Visual target tracking can be combined with a third feature of the software - autonomy in calculating where it is safe to reach out and analyse soil or rock with the science tools on the rover's robotic arm.

They've flown through space, been dropped onto a nearly airless surface, and survived months of subfreezing nights -- and they're actually IMPROVING in performance. I think the guys who designed and built these should be put in charge of just about EVERYTHING.
