NASA Missions Provide New Insights into 'Ocean Worlds' in Our Solar System,” announced a NASA press release in April. Life as we know it requires three primary ingredients: liquid water; a source of energy for metabolism; and the right chemical ingredients, primarily carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur. With this finding, Cassini has shown that Enceladus – a small, icy moon a billion miles farther from the sun than Earth – has nearly all of these ingredients for habitability. Come hear Chris Glein of Southwest Research Institute discuss Cassini’s discovery of molecular hydrogen, a possible food source for (hypothetical) microbes in Enceladus’ salty subsurface sea.
