DOI: 10.1016/j.icarus.2019.03.011
Abstract: Abstract Its extraordinary level of geologic activity, its potential for habitability, and the prospects of returning samples from its plume of erupting water ice make Saturn's small (∼500 km diameter) moon Enceladus a high priority… read more here.

DOI: 10.1016/j.icarus.2021.114466
Abstract: Abstract We use the recent models of Titan’s shape and gravity to estimate the large-scale density structure of its outer ice shell. We assume that the bottom boundary of the ice shell is an equipotential… read more here.

DOI: 10.1016/j.icarus.2021.114617
Abstract: Abstract Determining the thickness of Europa's outer ice shell is a key factor for understanding Europa's internal dynamics, evolution, and potential habitability. As such, one of the primary goals of any future lander mission to… read more here.

DOI: 10.1029/2024gl109144
Abstract: The potential habitability of Jupiter's moon Europa has motivated two missions: NASA's Europa Clipper and ESA's JUpiter ICy moons Explorer (JUICE). Both missions are equipped with ice‐penetrating radars which will transmit radio waves into the… read more here.

DOI: 10.1038/s41550-019-0958-x
Abstract: Active eruptions from the south polar region of Saturn’s ~500-km-diameter moon Enceladus are concentrated along a series of lineaments known as the ‘tiger stripes’ 1 , 2 , thought to be partially open fissures that… read more here.

DOI: 10.1038/s41561-019-0369-8
Abstract: Many icy Solar System bodies possess subsurface oceans. On Pluto, Sputnik Planitia’s location near the equator suggests the presence of a subsurface ocean and a locally thinned ice shell. To maintain an ocean, Pluto needs… read more here.

Subduction-like process in Europa’s ice shell triggered by enhanced eccentricity periods

DOI: 10.1126/sciadv.adq8719
Abstract: Jupiter’s icy moon Europa has a liquid water ocean beneath the ice shell and a geologically young surface, both related to extensive tidal processes. Interlaced by tectonic faults, the surface records convergent motions that induced… read more here.
