It may seem a fantastical notion, but hardly more so than the idea of building a starship of any kind. Yet in Orlando, Florida, not far from the launching site of the space program¡¯s most triumphant achievements, the government¡¯s Defense Advanced Research Projects Agency, the DARPA, drew hundreds in October to a symposium1 on the 100-Year Starship Study, which is devoted to ideas for visiting the stars. Participants¡ªan eclectic mix of engineers, scientists, science fiction fans, students, and dreamers¡ªexplored a mix of ideas, including how to organize and finance a century-long project; whether civilization would survive, because an engine to propel a starship could also be used for a weapon to obliterate the planet; and whether people need to go along for the trip.
