The Galileo orbiter and its Solid State Imaging system have increased the photographic coverage and resolution of Europa, revealing a complex surface that has been modified by tectonic deformation, impact craters on a wide range of scales, and possible cryovolcanic activity. The morphology of many of the features suggests that the depth to either liquid water or mobile-ductile ice was relatively shallow (< few kilometers) at the time of their formation. Characteristics of the mottled terrain and impact ejecta deposits suggest the presence of a shallow (˜km) subsurface zone beneath the bright icy crust. The Galileo Europa Mission, approved to continue orbital operations through 1999, will include at least nine close flybys of Europa, enabling global and regional mapping, along with high-resolution imaging of selected areas.
