Planet Four Uses Citizen Science To Identify Martian Feature

"Welcome to Planet Four, a citizen science project designed to help planetary scientists identify and measure features on the surface of Mars . . . the likes of which don't exist on Earth. All of the images on this site depict the southern polar region, an area of Mars that we know little about, and the majority of which have never been seen by human eyes before! We need your help to find and mark 'fans' and 'blotches' on the Martian surface. Scientists believe that these features indicate wind direction and speed. By tracking 'fans' and 'blotches' over the course of several Martian years to see how they form, evolve, disappear and reform, we can help planetary scientists better understand Mars' climate. We also hope to find out if these features form in the same spot each year and also learn how they change." More
