Thermophysical Properties of Europa’s Surface Constrained by Galileo Photopolarimeter-Radiometer Temperature Measurements

by Keith Cowing

Thermal measurements constrain the physical properties of icy satellite surfaces, including grain size, porosity, and regolith structure. On Europa, analyses of the Galileo Photopolarimeter-Radiometer (PPR) dataset revealed thermal inertia heterogeneities, […]

Pwyll and Manannán Craters as a Laboratory for Constraining Irradiation Timescales on Europa

by Keith Cowing

We examine high spatial resolution Galileo/NIMS observations of the young (~1 My – 20 My) impact features, Pwyll and Manannán craters, on Europa’s trailing hemisphere in an effort to constrain […]
