Using Juno Microwave Radiometer data, we find that the thermally conductive part of Europa's ice shell is 29±10 km thick, with centimeter-scale cracks, pores, or other reflective scatterers that extend to a depth of about 220 meters. We will discuss how varying our assumptions, including impurities in the ice, could affect these results.
