A crust that holds clues
Fractures and structures on Europa’s surface help scientists understand how its ice deforms. Several observations support the hypothesis of a salty ocean beneath the ice shell.
Jupiter’s role
Jupiter’s gravity contributes to flexing Europa as it orbits. This tidal flexing can produce internal heat, an important factor when investigating whether liquid water could persist.
A habitable place?
An ocean alone does not demonstrate that life exists. Europa Clipper is designed to study the ice shell, interior and composition to investigate whether conditions could be favourable for life.
