The brand stunt takes advantage of the publicity from an older controversy. Even though Mars is much smaller than Earth, it has a greater variation in surface elevation. "We cannot rule out the biological explanation. Carlotto has published over one hundred technical articles and written six books. When the European Space Agency stated that one of Mars’s moons, Phobos, appeared to be hollow, it mirrored the findings of Russian astrophysicist Dr. "Even if one is not convinced that the Viking LR results give strong evidence for life on Mars, this paper clearly shows that the possibility must be considered," says Chris McKay, PhD, Senior Editor of Astrobiology and an astrobiologist with NASA Ames Research Center, Moffett Field, CA. Levin and Straat evaluate the "non-biological hypotheses" to explain the Viking results, which many scientists support, but the authors conclude that the experimental evidence supports a biological explanation and the likelihood that microorganisms were able to evolve and adapt to be able to survive in the harsh conditions of the Martian environment. It had the capability to clearly photograph objects on Mars as small as a coffee table. Levin, Arizona State University, Tempe, and Patricia Ann Straat, National Institutes of Health, Bethesda, MD (retired), clearly outline the evidence to support the "biological hypothesis," which argues that the results of the 1976 Viking Labeled Release experiment were positive for extant microbial life on the surface of Mars.įurther, Drs. The Controversy Another probe, the Mars Observer, was scheduled to reach Mars in 1992. In "The Case for Extant Life on Mars and Its Possible Detection by the Viking Labeled Release Experiment," coauthors Gilbert V. Nanocrystals of magnetite (Fe3O4) in a meteorite from Mars provide the strongest, albeit controversial, evidence for the former presence of extraterrestrial. ![]()
