Saturn's Icy Moon Rhea: a Prediction for Bulk Chemical Composition and Physical Structure at the Time of the Cassini Spacecraft First Flyby

, 2005
I report a model for the formation of Saturn's family of mid-sized icy moons to coincide with the first flypast of Rhea by the Cassini Orbiter spacecraft on 26 November 2005.

Ocean stratification impedes particulate transport to the plumes of Enceladus

Communications Earth & Environment
Water-vapour plumes erupting from Enceladus’ south pole provide a window into the properties of its subsurface ocean, a prime target in the search for life. However, the extent to which plume material represents conditions at Enceladus’ depths is unclear,

Biological methane production under putative Enceladus-like conditions

Nature Communications, 2018
Many methanogenic archaea use H2 and CO2 to produce methane. Here, Taubner et al. show that Methanothermococcus okinawensis produces methane under conditions extrapolated for Saturn’s icy moon, Enceladus, and estimate that serpentinization may produce ...

Mapping spiral waves and other radial features in Saturn's rings

, 2017
We have analyzed the highest-quality images to be obtained by Cassini of Saturn's main rings after the Saturn Orbit Insertion (SOI) and before the Ring Grazing Orbits (RGO) and Grand Finale (GF).

Evidence of an Extended Alfvén Wing System at Enceladus: Cassini's Multi‐Instrument Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract We report in situ evidence for Enceladus' Alfvén wing system and its coupling with Saturn's ionosphere, based on multi‐instrument observations from the Cassini spacecraft. Analysis of 36 events, including 13 from non‐flyby paths, confirms the existence of a Main Alfvén Wing (MAW) current system generated at Enceladus, and associated Reflected ...

Differentiating Plumes and Local Torus Segments of Enceladus

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Enceladus's south polar plumes and their surrounding torus segments (local plasma regions formed by plume material diffusion) are key to understanding its magnetospheric interaction; however, clear observational criteria to distinguish them remain lacking.

Towards Determining Biosignature Retention in Icy World Plumes

Life, 2020
With the discovery of the persistent jets of water being ejected to space from Enceladus, an understanding of the effect of the space environment on potential organisms and biosignatures in them is necessary for planning life detection missions.

Seismic wave propagation in icy ocean worlds

, 2017
Seismology was developed on Earth and shaped our model of the Earth's interior over the 20th century. With the exception of the Philae lander, all in situ extraterrestrial seismological effort to date was limited to other terrestrial planets. All have in

Effects of immersed moonlets in the ring arc particles of Saturn

, 2020
Ring arcs are the result of particles in corotation resonances with nearby satellites. Arcs are present in Saturn and Neptune systems, in Saturn they are also associated with small satellites immersed on them.

Analysis of Ion Cyclotron Waves during Cassini’s Flybys of Enceladus

The Astrophysical Journal
Ion cyclotron waves (ICWs) are ubiquitous phenomena within Saturn’s magnetosphere, particularly in the vicinity of Enceladus. This study focuses on the Cassini spacecraft’s flyby data of Enceladus to investigate the spatial distribution and properties of
