The writing of a book such as this was an exciting process, made even more so by many people who helped me understand the dimensions of this subject and express it clearly. My wife, Sue, and my daughters, Emily Rosa and Stacia Elise, gave me a tremendous amount of support by just “being there” and understanding my peculiar early morning writing rituals. We are all going to look forward to having more breakfasts together again! I would like to thank my editor, Holly Hodder at Columbia University Press, for her enthusiasm for this project and the many excellent suggestions she made in helping me organize this material to make it readable. If you should find this book both thought provoking and captivating, it is largely to Holly's credit. I would also like to thank Susan Pensak for her excellent job of copyediting this book.
A subject as large as this, with as many facets, has to be written with great care, and I am grateful for the help I received from many colleagues and experts in space weather issues, NASA policy, and the industrial community. I would like to thank Joe Allen at the National Geophysical Data Center for his careful reading of the manuscript and numerous excellent suggestions and comments. I also thank George Withbroe, director of NASA's Office of Space Science, for explaining to me NASA's Living with a Star program. Any errors or misunderstandings you may uncover in this book about current policy, budget, or program issues in space weather are entirely the fault of the author. I would like to thank James Burch, Shing Fung, Dennis Gallagher, Jim Green, Pat Reiff, and Bill Taylor of the IMAGE satellite project for many conversations about
