The NASA Institute for Advanced Concepts (NIAC) is a truly remarkable site about some of the most compelling technology concepts and ideas. The NIAC's aim is to foster creative thinking and support research that could turn today's science fiction into tomorrow's science fact. Numerous projects, both from past efforts and from current investigations, are profiled on the institute's Web site. For example, one project outlines a potential method to make life on Mars possible. Others examine novel forms of propulsion for spacecraft. The studies span a wide range of disciplines, and their diversity is what makes this site so interesting.
