Using the most powerful cameras and spectrographic instruments ever sent to the red planet, the Mars Reconnaissance Orbiter played a pivotal role in collecting data to help scientists evaluate many potential landing sites for the Curiosity rover in greater detail. This slideshow contains information about the top four candidate landing sites, and Gale Crater, the final landing site for the Curiosity rover.
