THE MICROBES OF MARS A 2011 Addendum to Mars: The Living Planet by Barry E. DiGregorio

Dr. Gilbert V. Levin and Dr. Patricia Ann Straat were among the first astrobiologists NASA selected to be a part of the first and only search for life on Mars. They continue to claim that their highly sensitive microbial detection instrument called the Labeled Release experiment onboard the twin NASA Viking Landers found it in 1976. Yet the NASA Mars Exploration decision continues to ignore this evidence. "The Microbes of Mars" tries to answer this question through the words of Gilbert V. Levin and Patricia Ann Straat along with astrobiologists Joseph Miller and Chandra Wickramasinghe.
