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.

Modeling Titan’s Planetary Boundary Layer at the Huygens Landing Site: Evidence for the Role of Subsurface Methane Evaporation in Limiting Convective Growth

The Planetary Science Journal
The planetary boundary layer (PBL) is the region of the atmosphere directly impacted by surface processes and is thus potentially diagnostic of poorly constrained, unresolvable or unobserved surface properties.

A Youthful Titan Implied by Improved Impact Simulations

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract The small number of impact craters found on Titan suggests that its surface is relatively young. Previous work estimated its surface age to be between 200 and 1000 Myr. This estimate, however, is based on crater scaling laws for water and sand, which are not representative of the composition of Titan's icy surface.

Ice-Ocean Exchange Processes in the Jovian and Saturnian Satellites

, 2020
A growing number of satellites in the outer solar system likely have global oceans beneath their outer icy shells. While the presence of liquid water makes these ocean worlds compelling astrobiological targets, the exchange of heat and materials between ...

Constraining Time Variations in Enceladus’s Water-vapor Plume with Near-infrared Spectra from Cassini’s Visual and Infrared Mapping Spectrometer

The Planetary Science Journal
Water vapor produces a series of diagnostic emission lines in the near-infrared between 2.60 and 2.75 μ m. The Visual and Infrared Mapping Spectrometer (VIMS) on board the Cassini spacecraft detected this emission signal from Enceladus’s plume, and so ...

A survey of low-velocity collisional features in Saturn's F ring [PDF]

, 2014
Small (~50km scale), irregular features seen in Cassini images to be emanating from Saturn's F ring have been termed mini-jets by Attree et al. (2012). One particular mini-jet was tracked over half an orbital period, revealing its evolution with time and

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.

Astrometric observations of inner Saturnian satellites

, 2001
This paper presents observations of four inner Saturnian satellites (SX = Janus, SXI = Epimetheus, SXVI = Prometheus and SXVII = Pandora) made in August and November 1995 during the Earth and Sun crossings of Saturn's ring plane, respectively.

Saturnian Tidal Dissipation from Astrometric Observations

, 2010
International audienceOrbital satellite evolution is crucially linked to tidal dissipation inside the primary. Recently, tidal dissipation inside Jupiter has been derived successfully from the monitoring of the Galilean satellite motions, thanks to ...
