A growing number of satellites in the outer solar system likely have global oceans beneath
their outer icy shells. While the presence of liquid water makes these ocean worlds …

Geophysical data from the Cassini spacecraft imply the presence of a global ocean
underneath the ice shell of Enceladus, only a few kilometres below the surface in the South …

Orbital geophysical investigations of Enceladus are critical to understanding its energy
budget. In this paper, we identified key science questions for the geophysical exploration of …

A key objective for the future exploration of the icy moon Enceladus is the characterization of
the habitable conditions in its internal ocean. Radio science instrumentation on board a …

The origin of the unique south polar terrain on Enceladus is not well understood. Gravity
measurements made by Cassini suggest that the ice shell is thinner at the south pole than in …

After its formation, the Moon is widely believed to have possessed a deep, global magma
ocean. As it cooled, an anorthositic crust formed, floating atop this magma ocean and acting …

The catastrophic disruption of tri-layered spherical icy bodies is reported. The bodies are 19
cm in total diameter, with a central core, an intermediate water layer and an icy surface …

Abstract The Earth/Moon system likely results from a giant impact between a Mars-size
object and the proto-Earth. This high-energy impact leads to extreme conditions under which …

Catastrophic disruption is a possible outcome of high-speed collisions in the solar system.
The critical energy density Q*(impact energy/mass of the target), which is taken to mark the …

Several icy bodies in the outer Solar system have extensive internal oceans. In several
bodies the oceans are believed to be so extensive they decouple the interior core from the …
