   Looking at the Mars Rover tracks, I notice that at   
   regular intervals a few feet apart, the treadmarks   
   left in the dust are disturbed for a few inches before   
   continuing again.   
      
   Are the treads different at one point in their   
   circumference? Is the rover skidding to a halt   
   every few feet?   
      
   Incquiring minds want to know....
