These rovers can drive over rocks{#blank#}6{#/blank#}all kind of rough ground. They can also use cameras and send photos{#blank#}7{#/blank#} to Earth. First, the two rovers found chemicals and patterns (图文) in the rocks that were probably made by water. Then, they moved to another area and{#blank#}8{#/blank#}other rocks which may have been created by water. Now scientists think there was probably water on the planet long ago.
