With an all-new introduction, analyses, and additional photos, this book is destined to become a classic that will be remembered for ages to come. From the book that started it all, you will go further on this epic journey of discovery: from the sands of Mars, where you will learn the conventional wisdom about the evolution of the planet; to the discovery of the original "Viking" photos, where you will come to know the people who have tried to bring them and the "question of Cydonia" to the public's attention, along with the members of the planetary science community who are desperately trying to keep the mystery from ever reaching the public. You will follow the step-by-step investigation, the reaction, analyses and implications of what could be one of the most important discoveries in history; and you will be convinced that it is our right to know, whether or not our Government and science community believes that we are prepared for it.
