Craters!

I just spent about an hour analyzing craters on Mars. You can, too. Don’t believe me? Check out the Clickworkers Site and learn how to recognize craters and their shapes and ages. While the work for this site was originally done in 2000-2001, and the study for which it was created is over, the pages are a great way to learn how to analyze Martian surface features in much the same way planetary scientists (and their grad students) do. It’s a lesson in terrain recognition that anybody can do—and in my ever-lasting chase to convince folks that science is for everybody, this is one of those tasks that really brings it home! So, go give it a try, you future Martians, you!
