ISDC | The International Space Development Conference (ISDC) covers several broad areas of study related to building a spacefaring civilization, including transportation to and through space, technology needed to live and work in space, and Earth-based activities to advocate for or educate others about space development. The overall theme for ISDC 2011 is “From the Ground Up,” emphasizing the tools, resources, and social activities that must be accomplished to make a spacefaring civilization a reality. Participants are encouraged not just to describe an ideal “future state,” but to think about the technical, economic, or advocacy steps that must be accomplished to achieve a specific goal.
