A new mission to the icy moons of Jupiter

...energy? Do they have a source of water? Do they have sites where water and rock can interact? Are they the right temperature – it can’t be so cold that nothing could survive. And finally, life takes a long time to get started. Has there been enough time for the moon to become habitable? [Photograph of the surface of Europa. The grey-blue icy surface is criss-crossed...
