Looking for Life in All the Wrong Places: The Atacama, NASA Viking Experiments, and Salts

  • In 1976, NASA's two Viking spacecraft touched down on Mars, becoming the first successful landers on the red planet. On board Viking 1, the craft carried several biological experiments to search for life. While most scientists consider the results of those experiments to be negative for Martian life, one experiment gave a positive result. The resulting controversy has spanned decades, with numerous scientists weighing in. Now, Dirk Schulze-Makuch from the Centre of Astronomy and Astrophysics (ZAA) at Technische Universität Berlin questions how those experiments were performed in light of what we know of extremely dry environments here on Earth. These Mars analogs, such as the Atacama desert in Chile, show that while microbes can survive in harsh conditions, too much water becomes a problem. And those Viking experiments may have involved too much water.
    Join Dr. Franck Marchis as he discusses Dr. Schulze-Makuch's recent Nature Astronomy article and how we should follow the salts instead of the water.

    Great conclusion. We're looking at a dust ball and disregard all ocean satellites like planets in the solar system.
