Ozone Production by Electron Irradiation of Regolith Ice: Laboratory Study for the Icy Moons

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract We irradiate fine‐grained regolith pure water ice in ultra high vacuum with 5keV $5\,\text{keV}$ and 10keV $10\,\text{keV}$ electrons to study the radiolysis of water ice. The ice regolith is designed to closely mimic the physical characteristics of the surfaces of the icy moons of the Solar System.

Dynamical Evolution of V-shaped Collision Debris

The Astrophysical Journal
Catastrophic collisions between proto-satellites have been proposed as a possible origin of Saturn’s rings. This argument relies on the concept of the equivalent circular orbit.

Structure of Jupiter's High‐Latitude Storms: Folded Filamentary Regions Revealed by Juno

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Sprawling, turbulent cloud formations dominate the meteorology of Jupiter's mid‐to‐high latitudes, known as Folded Filamentary Regions (FFRs). A multi‐wavelength characterization by Juno reveals the spatial distribution, vertical structure, and energetics of the FFRs.

Magnetic signatures of plasma-depleted flux tubes in the Saturnian inner magnetosphere

, 2007
Initial Cassini observations have revealed evidence for interchanging magnetic flux tubes in the inner Saturnian magnetosphere. Some of the reported flux tubes differ remarkably by their magnetic signatures, having a depressed or enhanced magnetic ...

Oscillatory Loading in Ice Friction Experiments: Implications for Tidally Driven Activity Along the Tiger Stripes of Enceladus

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract We explored the effect of oscillatory loading on the frictional response of polycrystalline water ice and ice + ammonia to better understand the behavior of tidally modulated strike‐slip faults on the icy satellites of the outer solar system, particularly Saturn's moon Enceladus.

A Centroiding Algorithm for Point-source Trails

The Astronomical Journal
Astrometric measurements are significantly challenged by the relative motion between the point source and the telescope, primarily due to the difficulty in accurately determining the position of the point source at the mid-exposure moment.

TRAPPED‐S, a New Environment Model Framework for Saturn: Focus on Radiation‐Specification Model

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract As space agencies contemplate missions to the outer planets' systems and moons, entailing prolonged observations via local orbiters or potential landers, meticulous assessment of the local environment—encompassing radiation and plasma conditions—is paramount for the design of both the platform and scientific payload.

Extensional tectonics of the Saturnian Satellites

, 1985
The saturnian satellites were imaged by the Voyager spacecraft at sufficient resolutions to reveal landforms that indicate histories of extensional tectonics for several of these bodies.

Ocean Worlds Maintained by Ocean Tidal Heat Expected on Several Uranian Moons

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract In recent NASA decadal surveys, detecting oceans among Uranus' moons has been identified as a research priority in future missions. Currently, the prevailing view in planetary science is that the likelihood of finding oceans is highest on the larger moons, Titania and Oberon, due to their higher integrals of radiogenic heat sources.

Mapping of the icy saturnian satellites: Results from the first year inOrbit

, 2005
Images of the icy Saturnian satellites Mimas, Enceladus, Tethys, Dione, Rhea, Iapetus, and Phoebe, derived by the Voyager and Cassini cameras are used to produce new local high-resolution image mosaics as well as global mosaics [http://ciclops.org, http:/
