Robots are any machine or mechanical device that operates automatically with human-like skill.
-Search for and characterize a variety of rocks and soils that hold clues to past water activity. Including those that have minerals deposited by water-related processes such as precipitation, evaporation, sedimentation or hydrothermal activity.
-Determine the distribution and composition of minerals, rocks, and soils surrounding the landing sites.
-Determine what geologic processes have shaped the planet and affected the chemistry. ex) water or wind erosion, sedimentation, hydrothermal mechanisms, volcanism, and cratering.
-Help determine the accuracy and effectiveness of various instruments that survey Martian geology from orbit like the Mars Reconnaissance Orbiter
-Search for minerals that contain water or were formed in water, such as iron-bearing carbonates.
-Determine what processes help to form the rocks found.
-Look for natural clues to liquid water being present.
-Discover if there could be life.

-Opportunity has explored significant features of Mars such as the Victorian Crater and he Eagle Crater.
-Opportunity has lasted over 5 years, much longer than the anticipated 90 days.
-Both satellites and the rovers have shown that there once was water on the surface of mars.
