Exploring Europa and the Search for Life

The Planetary Society aims to advance space science, focusing on the search for life on Mars and Europa. Europa, a moon of Jupiter, is of particular interest due to its vast seawater beneath an icy crust, maintained by tidal forces. Observing Europa can be done with telescopes, and its geysers offer a potential way to study its seawater without landing. A proposed mission to Europa could discover life, involving international collaboration and costing $2 billion over ten years. This mission could change our understanding of life in the universe.
