Sampling the volcanic plumes at Io: Impact speeds and shock conditions

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The desire to sample material from the interior of Io, by flying through its volcanic plumes, requires consideration of the flyby speed and the types of sample collection techniques that can be utilized. Low speed collection (1–2.5 km s−1) would require an orbit around Io itself, which is unlikely due to the accumulated radiation dose that ...

Possibility for albedo estimation of exomoons: Why should we care about M dwarfs? [PDF]

open access: yes, 2016
Occultation light curves of exomoons may give information on their albedo and hence indicate the presence of ice cover on the surface. Icy moons might have subsurface oceans thus these may potentially be habitable.

Watery Enceladus [PDF]

open access: yesPhysics Today, 2011
In 1980, telescopes revealed that one of Saturn’s rings is centered at the orbit of Enceladus, a medium-sized Saturnian moon. It was the first hint that Enceladus is a world like no other.

Slantwise Convection and Heat Transport in Icy Moon Oceans

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Ocean heat transport on icy moons shapes the ice shell topography, a primary observable of these moons. Two key processes control the heat transport: baroclinic instability driven by surface buoyancy contrasts and convective instability driven by heating from the core.

Transient, Localized Flux Transport Revealed by Electron Microsignatures Downstream of Saturnian Moons

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract In Saturn's magnetosphere, the inward transport of magnetic flux is largely carried by localized injection flux tubes filled with warm, tenuous plasma, although their inflow speeds and spatio‐temporal properties remain poorly constrained. Here, we propose that these flux tubes can modify electron microsignatures, the small‐scale, absorption ...

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

open access: yesThe 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 ...

THEO Concept Mission: Testing the Habitability of Enceladus's Ocean

open access: yes, 2016
Saturn's moon Enceladus offers a unique opportunity in the search for life and habitable environments beyond Earth, a key theme of the National Research Council's 2013-2022 Decadal Survey. A plume of water vapor and ice spews from Enceladus's south polar

Atmospheric Ion‐Neutral Coupling as a Potential Driver for Saturn's Magnetospheric Antisunward Electric Field

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Saturn's inner magnetosphere contains a weak antisunward electric field that has influenced a wide array of different aspects of the magnetospheric conditions in that region. Previously, these currents have been explained as being caused by magnetospheric drivers.

Evidence of Gaia Enceladus Experiencing at Least Two Passages around the Milky Way

open access: yesThe Astrophysical Journal Letters
One of the major recent breakthroughs has been the discovery of the last major merger to happen in the history of the Milky Way. Around 10 Gyr ago, the galaxy Gaia Enceladus with an estimated ∼10% of the Milky Way mass, fell into the potential of our ...

A primordial origin for the atmospheric methane of Saturn's moon Titan [PDF]

open access: yes, 2009
The origin of Titan's atmospheric methane is a key issue for understanding the origin of the Saturnian satellite system. It has been proposed that serpentinization reactions in Titan's interior could lead to the formation of the observed methane ...
