New book on interstellar travel - Centauri Dreams
Summary - (Dec 2, 2004) Alpha Centauri is the nearest star to our Earth and Sun. Often, science fiction novels extol its ability to nurture new life or expound it as a destination for humankind. Paul Gilster in Centauri Dreams: Imagining and Planning Interstellar Exploration brings science and science fiction together in providing us with an up to date view on who's doing what to get people there, possibly starting as soon as this generation. He has only two exciting things to say about planning for the trip; it's here and it's now!
