Planet Four


Help planetary scientists identify and measure features on the s
Find and mark "fans" and "blotches" on the Martian surface

Planet Four is a citizen science project in which volunteers help planetary scientists identify and measure features on the surface of Mars.

Scientists need your help to find and mark ‘fans’ and ‘blotches’ on the Martian surface, features that indicate wind direction and speed. By tracking these features, you can help planetary scientists better understand Mars’ climate.

All of the images you'll see depict the southern polar region, a little known area of Mars. The majority of these images have never been seen by humans until now.

This is your chance to explore the surface of Mars like never before!
