Slantwise Convection and Heat Transport in Icy Moon Oceans
Geophysical 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.

Geophysical 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 ...

Dynamical Evolution of V-shaped Collision Debris
The Astrophysical JournalCatastrophic 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.

Electroanalysis, Volume 38, Issue 2, February 2026.Future in situ missions to ocean worlds of the outer solar system would benefit from the aqueous chemical measurements provided by ion‐selective electrodes (ISEs). Here, we verify the performance of ISEs after exposure to environments expected during outer Solar System missions, specifically near‐decade scale transit times, anhydrous conditions, low ...

Water Transport from Enceladus to the Rings
The Planetary Science JournalEnceladus continuously ejects approximately 300 kg s ^−1 of water vapor from its south polar regions, forming an extensive neutral gas torus around Saturn.

Origin of Hyperion and Saturn’s Rings in a Two-stage Saturnian System Instability
The Planetary Science JournalThe age of the rings and some of the moons of Saturn is an open question, and multiple lines of evidence point to a recent (few hundred Myr ago) cataclysm involving the disruption of past moons. The main driver of the evolution of the Saturnian system is

A Centroiding Algorithm for Point-source Trails
The Astronomical JournalAstrometric 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.

The Bombardment History of the Giant Planet Satellites
The Planetary Science JournalThe origins of the giant planet satellites are debated, with scenarios including formation from a protoplanetary disk, sequential assembly from massive rings, and recent accretion after major satellite–satellite collisions.

Topographic Relaxation of Complex Impact Craters in a Clathrate Crust on Titan
The Planetary Science JournalTitan’s impact craters are significantly shallower than fresh craters on Ganymede, which are often used as templates for fresh craters on Titan. The presence of a clathrate crust on Titan, which would insulate the ice shell and maintain warmer ice near ...

Raman Spectroscopy of Salt Deposits from the Simulated Subsurface Ocean of Enceladus
The Planetary Science JournalEnceladus may host a subsurface ocean with biologically relevant chemistry. Plumes released from this ocean preserve information on its chemical state, and previous analyses suggest weakly to strongly alkaline pH.
