Opportunity has found more evidence for water in Mars' past. It has sent back images of cracks on rock. This suggests that there was water on Mars after the large lakes dried up. "These [cracks] are ... well-known in Earth to be associated with water," scientist John Grotzinger said. "The rocks become impregnated with water, it dries out and pulls in all directions."

Spirit has also found evidence of water. After driving to Colombia Hills, it found that "[e]very single rock in the hills has shown alteration by liquid water," Steve Squyres said. The rocks Spirit analyzed were older than the floor of its landing spot, Gusev Crater.
