Effect of temperature-dependent ice properties on ice shell convection for icy ocean worlds
Ice shell dynamics are a critical control on the habitability of icy ocean worlds. Here, we present a systematic study evaluating the effect of temperature-dependent material properties on these dynamics. We review the published thermal conductivity data for ice, which demonstrates that the most …

Deformation of icy moons induced by heat flux variations from the ocean
… harbor liquid water oceans beneath their icy shells, offering possibly habitable environment or even an opportunity for the emergence of life outside the Earth. Icy moon Titan possesses a dense atmosphere and liquid hydrocarbon lakes on its surface, yet it remains unclear how are the volatiles …

Icy Satellite Tectonic, Geodynamic and Mass Wasting Surface Features: Constraints on Interior Processes and Evolution
… regions on Europa and what they reveal about ice shell thickness, iv) relaxed impact craters and the thermal history of Ganymede, and v) the size-velocity distribution of ejecta fragments from large cratering events on Europa and Ganymede.</p>

Modeling Non-Rotational Ocean Circulation and Heat Distribution in Icy Moons
Subsurface oceans beneath the ice shells of icy moons like Europa and Enceladus are considered promising environments for extraterrestrial life. Their long-term habitability depends on internal heating and efficient vertical heat transport to maintain liquid water beneath the surface. This study …

An investigation of the effect of cryoprotective agents on intermolecular disulfide formation
… Whan the Thiogel is frozen slowly, the ice forms as a shell on the gel surface. It is the removal of water from the Thiogel to this ice shell which causes the increase in the rate of formation of disulfide bonds. As the water is removed the protein molecules come closer together, …

Dike-Driven Hydrothermal Processes on Mars and Sill Emplacement on Europa
… collected in aquifers, possibly stored beneath ice. On the icy moon Europa, I modeled a proposed sill emplacement mechanism using a finite element code and found that water could flow up through an approximately 10 km thick ice shell without freezing. The analysis also found that shallow cracks …

Experimental Validation of Melt Probe Models for the Exploration of Ocean Worlds
… volumes of water may exist under a layer of ice, are strong candidates for the first discovery of extraterrestrial life. Jupiter’s moon Europa is currently believed to have at least twice as much water as Earth. A key remaining challenge is developing a probe that can traverse tens of …
