Analytical Modeling of Hot Ion Interchange Injections in Saturn's Magnetosphere

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Cassini's CHarge Energy Mass Spectrometer (CHEMS) instrument collected energetic plasma data from 2004 to 2017, including hundreds of observations of small‐scale nearly dispersionless “local” injection events into the inner magnetosphere. This study assesses whether these interchange‐like injections are a channel‐like structure still connected

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

, 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 ...

Curtain-based Maps of Eruptive Activity in Enceladus’s South-polar Terrain at 15 Cassini Epochs

The Planetary Science Journal
We map surface eruptive activity in Cassini images of Enceladus’s south-polar terrain (SPT) at 15 epochs spanning late 2009 to late 2015 using a refined curtain approach derived from that of J. N. Spitale et al. (S2015).

Tethys’s Heat Fluxes Varied with Time in the Ithaca Chasma and Telemus Basin Region

The Planetary Science Journal, 2023
We investigated how lithospheric heat fluxes varied temporally and spatially on the Saturnian moon Tethys, focusing on the region of Ithaca Chasma that overprints Telemus Impact Basin.

Magnetic Field Disturbance Induced by the Enhanced Suprathermal Ring Current in the Magnetosphere of Saturn

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Saturn's ring current, which modulates the global magnetic field configuration, varies dynamically with hot plasma injections. However, quantifying transient magnetic field disturbances remains challenging in the absence of in situ measurements on Saturn's surface.

IR SPECTRAL MAPPING OF THE MARTIAN SOUTH POLAR RESIDUAL CAP USING CRISM [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
Polycyclic aromatic hydrocarbons (PAHs) are considered to be important in theories of abiogenesis (Allamandola, 2011) . There is evidence that PAHs have been detected on two icy Saturnian satellites using the Visual and Infrared Mapping Spectrometer ...

Peaking Into Oberon's Past: An Isolated Peak Could Imply the Existence of a Subsurface Ocean or Convecting Ice Shell

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract The Uranian moons, last visited in 1986 by Voyager 2, remain an intriguing yet under‐explored set of targets. Understanding the thermal structure and evolution of these moons is key to addressing one of the highest priority goals in planetary science: identifying if any are ocean worlds today or have been in the past. On Oberon, one feature in

Enough Sulfur and Iron for Potential Life Make Enceladus’s Ocean Fully Habitable

The Astrophysical Journal Letters
The Cassini spacecraft revealed life-forming elements like CHNOP and diverse organic compounds from Enceladus’s ocean. However, the availability of minor but bio-essential nutrients such as iron and sulfur remains unknown.

AI Based Velocity Calibration for Cassini's Cosmic Dust Analyzer (CDA)

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract This paper presents a novel AI‐based velocity calibration method for the Cosmic Dust Analyzer (CDA) onboard the Cassini spacecraft, in particular for impacts on the large Impact Ionization Detector (IID). The legacy polynomial calibration function, derived from laboratory measurements at a dust accelerator facility, assigns a velocity ...
