Fragmentation of Hyperion and cratering of Saturn's satellites

The authors summarize the arguments suggesting a collisional fragmentation of the Saturnian satellite Hyperion, and a subsequent orbital evolution of the fragments controlled by Titan's resonant perturbations. As a consequence of this evolution, most fragments eventually either collided with Titan or were ejected from the system, but a minor fraction of them probably impacted with the inner moons and contributed to the cratering of their icy surface.
