Great book. A comprehensive, easy to read summary of (nowadays and future)propulsion techniques, engineering constraints, practical aspects and plans to explore interstellar space. (Also see thread "far out" on the "beyond" topic). Especially good during summer holidays .....so you can read it at once.

Marcel.

Much appreciated, Marcel. Let me also add that the topics in the book are updated at www.centauri-dreams.org, which is a site I maintain to track developments in interstellar topics ranging from propulsion to planetary detection, communications and robotics.
