From Scientific American This book is long overdue. Hardersen has marshaled an impressive array of brass-tacks facts documenting the enormous benefits that the space program has brought to the American public. Those skeptical that the expenditures this nation has made in pushing the space frontier are being rewarded by ample economic returns will find in this book necessary medicine. Those already advocating space exploration will find here some of the tools they need to pry open the eyes of even the most closed minded. Read this book and then mail it to your congressman. Hardersen's is a message they need to hear on Capital Hill.
