In 1976, NASA sent four Viking spacecraft to Mars to photograph the planet, including a mile-long mesa that uncannily resembles a human face. In this wide-ranging and profound analysis of the Mars data, Hoagland takes readers step by step through these NASA images and the evidence that a highly advanced civilization may have lived and built upon Mars hundreds of thousands of years ago. 50 photographs; 10 line drawings; maps and charts.Richard C. Hoagland is a former space science museum curator; a former NASA consultant, and during the historic Apollo Missions to the Moon, was science advisor to Walter Cronkite and CBS News. For over 20 years, Hoagland has been leading an outside scientific team in a critically acclaimed independent analysis of possible intelligently-designed artifacts on Mars. Richard and his team's investigations have been quietly extended to include over 30 years of previously hidden data from NASA, Soviet, and Pentagon missions to the Moon.enterprisemission.com
