The end of 2014 saw the publication of our book 'Beyond the Boundary': exploring the science and culture of interstellar spaceflight. The book features contributions from members across the organisation on diverse subjects such as the scientific and societal benefits of interstellar exploration, defining the fundamental requirements, the use of wormholes and faster than light travel, interstellar communications, launch vehicles and many other chapters exploring missions scenarios, propulsion options and the Search for Extraterrestrial Intelligence (SETI).
Principium is the Initiative for Interstellar Studies quarterly featuring articles on deep space propulsion, spacecraft designs and concepts, interviews with prominent personalities in the interstellar community as well as i4is members, and features on SETI, exoplanets, interstellar physics, science fiction and the exploration and utilisation of the Solar System.
This newsletter is free to download as a PDF from these pages, where we will keep a growing backlist of issues. If you would like to contact the Editor, please write to us. Also, if you enjoy reading Principium, don’t forget to share it with your friends, colleagues and relatives and spread the word about i4is’ mission and the quest to develop an interstellar spacecraft.
