The Red Planet is a unique and dynamic world. Through the power of the Internet and its volunteers, we can explore the surface, climate, and history of Mars with our suite of the Planet Four projects. It is difficult if not impossible for computer algorithms to accurately map individual polar seasonal fans, spot araneiform (‘spider’) erosion, and identify polygonal ridges. Computers just aren’t good enough to do the job yet, but these features visible from orbit are easily spotted by the human eye. Volunteers from around the world have contributed to the Planet Four projects by mapping the seasonal fans, polygonal ridges, and araneiforms in Mars Reconnaissance Orbiter imagery.
With the help of volunteers, we are discovering new insights into the processes active in the past and present on the Red Planet. Join us at https://planetfour.space .
