Sand Robotics Challenge, Sponsored by NASA and Adams State University

Great Sand Dunes are very similar to the dunes on planet Mars, where NASA rovers explore and do scientific research. Each spring, NASA and Adams State University sponsor a sand robotics challenge, where college student teams and the general public can compete with their own homemade rovers and learn about the technology of Mars rovers! The competition takes place in the Medano Creekbed, outside the designated wilderness area of the dunefield. Learn more on the Colorado Space Consortium's website. Free entrance to the park this day!
