The Lure of Europa

On the Cover: ON THE COVER: With its probable ocean of liquid water and its geologic dynamism, Jupiter’s moon Europa is one of the most promising places in our solar system to search for signs of life. Scientists continue to use Galileo data, as exemplified by these enhanced color views (in various resolutions) of Europa’s fractured and mottled surface, to refine our view. Only a new mission, however, can bring us fresh, close-up views of this tantalizing world. Now on NASA’s drawing table, the Europa Clipper could do that—and more.
