Myself, the editor of the book, I am the chair of the largest project on space weather, gathering 26 countries. I am a permanent researcher at CNRS a" Laboratoire de PlanA(c)tologie de Grenoble. I study space weather at Earth, but also at other planets (Mars, Jupiter, Venus, Titan). I published more than 50 scientific papers on these topics. This book is my tenth book. I published 9 books on space, space weather, and a ] philosophy in French. One of them on space weather has been translated and published in December 2005 by Springer (Space weather, environment and societies, Jean Lilensten et J. Bornarel).
