| Abstract: | A mission to Mars is both inevitable and potentially of great value, argues the author of this Viewpoint, but for a variety of reasons - financial, technical and political - it is feasible only as an international cooperative venture. Several models of international cooperation already exist, but perhaps the Association of Space Explorers, with its membership drawn from 18 spacefaring nations, and the proposed International Space Exploration Institute offer the most promising avenues for taking the project forward. |
