Secondary craters from large impacts on Europa and Ganymede: Ejecta size–velocity distributions on icy worlds, and the scaling of ejected blocks

•Fields of secondary impact craters around three large icy primary craters were mapped.•We characterize size–velocity distributions of ejecta fragments from these craters.•Maximum fragment sizes scale as primary diameter and inversely with ejection velocity.•Spall theory underpredicts icy fragment s...
