Local Time Asymmetry in Energetic Electron Distribution Within Saturn's Inner Magnetosphere

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Electrons of several hundred keV in Saturn's ring current are important seed components of the radiation belt. In this study, we have statistically analyzed the spatial distribution of energetic electrons on the equatorial plane of the inner magnetosphere based on the Cassini in situ observations.

The Effect of Salinity on Ocean Circulation and Ice–Ocean Interaction on Enceladus

The Planetary Science Journal
Observational data suggest that the ice shell on Enceladus is thicker at the equator than at the pole, indicating an equator-to-pole ice flow. If the ice shell is in an equilibrium state, the mass transport of the ice flow must be balanced by the ...

Crater Observing Bioinspired Rolling Articulator (COBRA)

Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.
Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.

Is Enceladus' plume tidally controlled?

Geophysical Research Letters, 2008
Explanations for the plume of gas, water vapor and ice particles jetting from rifts in Enceladus' south polar region include boiling of liquid water and dissociation of clathrate hydrates.

A Recent Impact Origin of Saturn’s Rings and Mid-sized Moons

The Astrophysical Journal, 2023
We simulate the collision of precursor icy moons analogous to Dione and Rhea as a possible origin for Saturn’s remarkably young rings. Such an event could have been triggered a few hundred million years ago by resonant instabilities in a previous ...

Long-term Evolution and Stability of Saturnian Small Satellites: Aegaeon, Methone, Anthe, and Pallene

, 2017
Aegaeon, Methone, Anthe, and Pallene are four Saturnian small moons, discovered by the Cassini spacecraft. Although their orbital characterization has been carried on by a number of authors, their long-term evolution has not been studied in detail so far.

Defining soil: Proposals of zero‐states, active layer, and págousols (from ice parent materials) to fundamentally expand soil science

Soil Science Society of America Journal, Volume 90, Issue 2, March/April 2026.
Abstract Recent publications in soil science have reopened discussions over how soil and soil science should be defined, reflecting productive tension between historical constructs and the evolving frontiers of the discipline. While new definitions offered over the past decade provide valuable perspectives, they inevitably rely on past conventions and ...

Methanol on Enceladus [PDF]

Geophysical Research Letters, 2009
Near infrared spectra of the surface of Enceladus returned by Cassini show the presence of an absorption feature at 3.53 μm, ascribed by Brown et al. (2006) to “short chain organics,” and by Newman et al. (2007) to hydrogen peroxide. We assign this feature tentatively to methanol.

Enceladus’s Tidal Heating: A Simple Approach

The Planetary Science Journal
Saturn’s moon Enceladus has a global ocean that is covered by an ice shell. The moon’s eccentric orbit forces the shell to librate, which distorts the shell and thereby generates heat.

The three-dimensional structure of Saturn's E ring

, 2012
Saturn's diffuse E ring consists of many tiny (micron and sub-micron) grains of water ice distributed between the orbits of Mimas and Titan. Various gravitational and non-gravitational forces perturb these particles' orbits, causing the ring's local ...
