A range of science investigations suggest that it contains the key ingredients for habitability, notably energy, chemistry, and liquid water (e.g., Wackett et al., 2004; Hand et al., 2009). EuropaÕs surface is geologically complex and, based on the dearth of impact craters, interpreted to be as young as ~60 Ma (e.g., Lucchitta and Soderblum, 1982; Pappalardo et al., 1999; Bierhaus et al., 2001, 2009; Figueredo and Greeley, 2004; Prockter and Schenk, 2005; Doggett et al., 2009). The array of geologic features that characterize the surface include extensive ridged plains, regions of broad disruption termed chaotic terrain, long, quasi-linear ridges that span thousands of kilometers, and bands up to 60 km wide and that extend 100s of km (e.g, Prockter and Patterson, 2009) (figure 1). These features, along with other geophysical measurements (Kivelson et al., 2000), suggest the presence of a global briny liquid water ocean beneath the ice shell (Cassen et al., 1979, 1982; Anderson et al., 1998; Pappalardo et al., 1999; Kivelson et al., 2000; Kargel et al., 2000; Schubert et al., 2009; Nimmo and Manga, 2009; Zolotov and Kargel, 2009; Vance and Goodman, 2009). It was not until the arrival of the Galileo spacecraft in 1995 that the true nature and level of complexity of the surface was revealed. Although image data returned by Galileo provided insight into the structure of a variety of regions, the entire satellite has yet to be observed at a regional scale (less than 250 m/pixel) and the detailed geologic nature of much of its surface remains a mystery. Establishing the global context of the distribution and timing of Europan geologic units forms a basis to understand regional and local scale processes, serves as a tool for the planning of future missions, and most of all is essential to gaining insight into the potential habitability of this icy world. Purpose: 1:10,000,000-scale geologic map of Europa.
