Planet Mappers: Mercury Edition has long been in beta, but we're finishing up the tools and pages to give you a closer look at the closest planet to the Sun.

Check out Mercury Mappers now with the new linear feature tool: http://cosmoquest.org/projects/mercury_mappers/

We've added pages on the science, missions, and a video tutorial to help you get started. Mercury is an interesting world with very different features from the Moon and Vesta. You'll see lots of secondary craters and crater chains, plus linear cracks in the floors of large craters. I hope you get as lost in the terrain as I was when I started making tutorials for Mercury Mappers. :-)

Discuss the planet, the science, and the images here!
