EUROPA'S SURFACE COMPOSITION AND MORPHOLOGY ­ IMPLICATIONS FOR INSITU TARGET DEFINITIONS
Pappalardo et al.

General goals for surface and near surface studies:
· ·
NIMS spectra of Europa (cycles)

Verification of the existence of a subsurface ocean Characterization of the ice crust, dynamics of the crust, estimation of thickness (globally and regionally), tidal forces Surface and near surface composition Habitability verification studies

· ·
H2SO4 8 H2O

Definition sources:
· Surface topography, morphology and composition (Galileo SSI, NIMS data)

H2SO4 n H2O

Carlson et al.

EUROPA'S SURFACE COMPOSITION AND MORPHOLOGY ­ IMPLICATIONS FOR INSITU TARGET DEFINITIONS
Requirements and motivation:
· · Combination of global (orbital) and regional (in situ) studies Ground truth for surface composition analysis from orbit (ice, minerals, organics) and surface temperature (regionally, insitu) Nature of the non-icy material of the surface cracks and the surface ice (globally, remotely) Pristine material and recently erupted
