On the surface of Mars lies a formation that looks remarkably like a humanoid face. Forever staring up into the vastness of space it has attracted our attention. For some, that is why it is there, beckoning us to come and explore. Others believe that it is simply an odd looking geological landform - a formation carved over the ages by the random forces of nature. It is our imagination and our desire to find other life in the universe that makes us see it as an intelligently crafted object. Opinions about the possibility of life on Mars have changed over the years from Percival Lowell's canals, to the dead planet image by the earlyMarinermissions to Mars, to the enormous volcanoes, great canyon systems, and channels carved by water seen byMariner 9andViking. In the first edition ofThe Martian Enigmas, Dr. Mark J. Carlotto presented a detailed analysis of the controversial Viking photographs. The revised edition greatly expands on his early work, containing new research results that add further support to the claim that these objects may be precisely what many scientists have sought for decades: the first hard evidence that we are not alone.

Mars Geological Enigmas: From the Late Noachian Epoch to the Present Day presents outstanding questions on the geology of Mars and divergent viewpoints based on varying interpretations and analyses. The result is a robust and comprehensive discussion that provides opportunities for planetary scientists to develop their own opinions and ways forward. Each theme opens with an introduction that includes background on the topic and lays out questions to be addressed. Alternate perspectives are covered for each topic, including methods, observations, analyses, and in-depth discussion of the conclusions. Chapters within each theme reference each other to facilitate comparison and deeper understanding of divergent opinions. - Offers a transchronological view of the geological history of Mars, addressing thematic questions from a broad temporal perspective - Discusses outstanding questions on Mars from diverging perspectives - Includes key questions and answers, as well as a look ahead to which puzzles remain to be solved

In this provocative book, The Cydonia Codex authors George J. Haas and William R. Saunders use archaeological research discoveries and photographs from NASA and other space programs to document the uncanny similarities between Martian and now-extinct Earth cultures. The Martian Codex begins with a review of the thirty-year history of documenting the famous “Face on Mars” landform from NASA’s first photographs in 1976 to the Mars Reconnaissance Orbiter’s HiRISE shots in 2007. Detailed analysis shows it as a split-faced structure that precisely resembles a set of masks from a temple in Cerros, Mexico. Part two provides additional examples of two-faced and composite structures all over the red planet. Haas and Saunders explore a series of recurring motifs by providing side-by-side views of the Martian geoglyphs with their terrestrial pre-Columbian counterparts. The results substantiate a commonality between two worlds in that both depict specific gods and characters from the creation mythology of the Mayan people, as recorded in the sacred Popol Vuh. This fact-based book represents the most persuasive argument yet that extraterrestrials may indeed have appeared on Earth during an earlier era.

Astronomer Kidger has spent his career helping the general public understand the nature of the universe and astronomy. In "Astronomical Enigmas," he offers answers to the questions he is asked most frequently.

This engaging and groundbreaking archaeological treatise mixed with cultural commentary argues that our future on Mars depends on our understanding of its remarkable past. Much to the surprise of scientists and researchers, the latest cosmic discoveries offer strong evidence that points to an extinct civilization on Mars. What happened to it? And what does this mean for us on Earth? With in-depth research and accessible prose, After the Martian Apocalypse explains how our own survival may depend on confronting the strange and ancient truths to be found on the Red Planet. Challenging orthodox notions of humanity’s role in space, this unputdownable book effortlessly proves that to truly understand our own world, we must first understand our unsettling and enigmatic planetary neighbor.

An asteroid transformed Mars from a lush planet with rivers and oceans into a bleak and icy hell. Is Earth condemned to the same fate, or can we protect ourselves and our planet from extinction? In his most riveting and revealing book yet, Graham Hancock examines the evidence that the barren Red Planet was once home to a lush environment of flowing rivers, lakes, and oceans. Could Mars have sustained life and civilization? Megaliths found on the parched shores of Cydonia, a former Martian ocean, mirror the geometrical conventions of the pyramids at Egypt's Giza necropolis. Especially startling is a Sphinx-like structure depicting a face with distinguishable diadem, teeth, mouth and an Egyptian-style headdress. Might there be a connection between the structures of Egypt and those of Mars? Why does NASA continue to dismiss these remarkable anomalies as "a trick of light"? Hancock points to the intriguing possibility that ancient Martian civilization is communicating with us through the remarkable structures it left behind. In exploring the possible traces left by the Martian civilization and the cosmic cataclysm that may have ended it, The Mars Mystery is both an illumination of our ancient past and a warning--that we still have time to heed--about our ultimate fate.
