Welcome to the 2013 Mars Cargo Landing System Design Challenge! This year, the Mars Madness Foundation has challenged citizen scientists and engineers to create a Mars Cargo Landing System (MCLS) to deliver 40,000 kg in materials to the Martian surface from a low Mars orbit. The Foundation is committed to helping improve the technology available to both government and private enterprises as they pursue their quest to settle Mars and Challenge entries that are approved by the foundation will be added to a data base of potential solutions that will be shared with these organizations. All teams with approved designs will be awarded a certificate of achievement for their contributions to the Mars Landing Community.
