Mars is an alien place. In some ways, it's a lot like Earth: there are processes (both geologic and atmospheric) that are continually reshaping the Martian surface. These processes are much, much different on Mars, however, leading to landscapes unlike anything you've ever seen.
In honor of the Mars Science Laboratory rover landing on Mars this weekend, NASA's Marshall Space Flight Center has picked this group of images showcasing some of the weirdest and most interesting parts of the planet. Whether taken from orbit by a satellite or from very close up by a rover, Mars has some fascinating geology going on, and you can see the entire series of images in the gallery below.
