Inductive Response of Enceladus' Ice Shell and Potentially Stratified Ocean

Earth and Space Science
Saturn's moon Enceladus harbors a global subsurface ocean beneath its icy crust. Understanding the structure and composition of this ocean and ice is critical to assessing its potential habitability. Modern electromagnetic (EM) sounding techniques, which

Spatial Distribution of Glycine and Aspartic Acid in Rapidly Frozen Brines Relevant to Enceladus

The Planetary Science Journal, 2023
Saturn’s moon Enceladus harbors a global, subsurface liquid ocean beneath an icy crust that actively erupts water jets from fissures in its south pole. Data returned from the Cassini mission have identified salts and organic matter within these ejected ...

Saturn's icy satellites and rings investigated by Cassini - VIMS. III. Radial compositional variability

, 2012
In the last few years Cassini-VIMS, the Visible and Infared Mapping Spectrometer, returned to us a comprehensive view of the Saturn's icy satellites and rings. After having analyzed the satellites' spectral properties (Filacchione et al.

Characterization of the Outer Uranian Rings in the Visual and Near‐IR Using Keck, JWST, and HST Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract We present observations of the Uranian outer ring system at near‐infrared and visible wavelengths. Observations with the Keck Telescope were taken in July‐August 2007 at 2.12 and 1.63 μm, when the ring plane was almost edge‐on (ring opening angle B=0.62 $B=0.62$–0.24° ${}^{\circ}$). These data showed, for the first time, the μ ring at infrared

Investigating the Detectability of Body Wave Phases From Tidal Ice Cracking Events on Titan With the Dragonfly Short‐Period Seismometer

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Detecting seismic activity on Saturn's icy moon Titan during the Dragonfly mission could provide crucial information on its internal structure. The geological complexity of the moon's surface suggests significant cyclic tidal deformation, likely leading to the fracturing of the ice shell.

The Potential for Organic Synthesis in the Ocean of Enceladus

The Astrophysical Journal
The Cassini spacecraft detected a soup of organics in the plume of Saturn’s moon Enceladus. Those compounds could provide building blocks for the potential emergence or sustenance of microbial life in Enceladus’ subsurface ocean. However, the sources and

Magnetic Field Induced by Convective Flow in Ganymede's Subsurface Ocean

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract It has been suggested that the convective flows in Ganymede's subsurface ocean can generate a magnetic field that is strong enough to be measured by future space missions. Here, we investigate this hypothesis by developing a numerical model of Ganymede's magnetic field induced by the motion of salt water in its interior.

Giant impacts in the Saturnian System: a possible origin of diversity in the inner mid-sized satellites

, 2011
It is widely accepted that Titan and the mid-sized regular satellites around Saturn were formed in the circum-Saturn disk. Thus, if these mid-sized satellites were simply accreted by collisions of similar ice-rock satellitesimals in the disk, the ...

Magnetospheric considerations for solar system ice state [PDF]

, 2018
The current lattice configuration of the water ice on the surfaces of the inner satellites of Jupiter and Saturn is likely shaped by many factors. But laboratory experiments have found that energetic proton irradiation can cause a transition in the ...
