The goal of the Exploration Design Challenge is for students to research and design ways to protect astronauts from space radiation. NASA and Lockheed Martin are developing the Orion spacecraft that will carry astronauts beyond low Earth orbit and on to an asteroid or Mars. Protecting astronauts from radiation on these distant travels is an important — and very real — problem that needs solving. NASA would like your help. Check out the challenges for K-4, 5-8, and 9-12.
