Retrograde Predominance of Small Saturnian Moons Reiterates a Recent Retrograde Collisional Disruption

The Planetary Science Journal
We report the discovery and careful orbital determination of 64 new irregular moons of Saturn found in images taken using the Canada–France–Hawaii Telescope from 2019 to 2021, bringing the total number of Saturnian irregulars to 122.

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.

Onboard Science Instrument Autonomy for the Detection of Microscopy Biosignatures on the Ocean Worlds Life Surveyor

The Planetary Science Journal
The quest to find extraterrestrial life is a critical scientific endeavor with civilization-level implications. Icy moons in our solar system are promising targets for exploration because their liquid oceans make them potential habitats ...

Phase‐Space Synchronization Driven by Moon‐Magnetosphere Coupling in Gas Giants

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We present a new theoretical framework to describe the rapid and spatially localized loss of energetic particles in planetary radiation belts, focusing on interactions between gas giant magnetospheres and their moons. Observations show that flux depletions—known as microsignatures—often refill on timescales comparable to a single drift period,

Surface ages of mid-size Saturnian satellites [PDF]

, 2020
The observations of the surfaces of the mid-sized saturnian satellites made by Cassini–Huygens mission have shown a variety of features that allows study of the processes that took place and are taking place on those worlds.

JWST/NIRSpec Reveals the Atmospheric Driver of Saturn's Variable Magnetospheric Rotation Rate

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Past measurements of Saturn's upper atmosphere have allowed only a broad scale view of the temperature and ion density structures within the auroral region. However, Saturn's auroral currents include a planetary period current component that is produced by neutral atmospheric flows.

Saturnian Irregular Satellites as a Probe of Kuiper Belt Surface Evolution

The Planetary Science Journal
We present the JWST NIRSpec PRISM 0.7–5.3 μ m spectra of Albiorix and Siarnaq and the NIRSpec G235H/G395M 1.7–5.3 μ m spectra of Phoebe, the three largest Saturnian irregular satellites.
