Exploratour: NASA's Exploration for Life
The Mars Pathfinder mission was able to find out that the rocks of Mars can be studied in a way that is similar to the very same rock cycle on the Earth. Mars Pathfinder also verified that regions of Mars which looked like the remains of water flowing from Earth really are the remains of ancient water flows.
