• Science Goal: Explore Europa to investigate its habitability • Science Objectives: • Ice Shell & Ocean: Characterize the ice shell and any subsurface water, including their heterogeneity, ocean properties, and the nature of surface-ice-ocean exchange • Composition: Understand the habitability of Europa's ocean through composition and chemistry • : Understand the formation of surface features, including sites of recent or current activity, and characterize high science interest localities

Note: Recent Activity cross-cuts through all three principal science objectives

E UROp A 2 CLIppE R Mission Overview

• Europa Clipper is a NASA Flagship mission, scheduled for launch in the mid-2020’s. • Payload instruments will work together to investigate Europa’s habitability • Mission design: more than 50 globally distributed flybys of Europa over ~3.8 years • Observe widely distributed set of geologic terrains • Provide data to constrain and test geophysical and geochemical models of ice shell and ocean • The team uses a “One Team” philosophy • Science team members are considered part of a single, integrated science team • This avoids stovepiping of science efforts • “Rules of the Road” document spells out expectations of inclusiveness, respect, and equitable treatment for all members of science team
