The Vertical Structure of the F Ring of Saturn from Ring-Plane Crossings

open access: yes, 2013
We present a photometric model of the rings of Saturn which includes the main rings and an F ring, inclined to the main rings, with a Gaussian vertical profile of optical depth.

The E-ring of Saturn

open access: yesInternational Astronomical Union Colloquium, 1981
AbstractThe origin of the E-ring of Saturn and its relationship to Enceladus is a well known problem. Rather than assuming that the ring was formed as a result of one big impact long ago or that it is a consequence of ejection of subcrustal water by tidally induced stresses and cracks of the satellite, it is proposed that the ring is formed as a ...

A Small Pathbreaking Spacecraft: Giants of Space Research (Bernard Blake, Dieter Hovestadt, and Edward Stone)

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract The Solar, Anomalous, and Magnetospheric Explorer (SAMPEX) mission launched in July 1992 was the first NASA “Small Explorer” project. It had the goal to show how space missions could be developed much more rapidly than had become the situation in the 1980s and 1990s.

JWST/NIRSpec Detection of Complex Structures in Saturn's Sub‐Auroral Ionosphere and Stratosphere

open access: yesGeophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Past observations of Saturn's sub‐auroral ionosphere have provided no detailed longitudinal information, and variations in underlying stratospheric emission from methane fluorescence have never been resolved spatially. Here, we present the first near‐infrared observations of Saturn using JWST's NIRSpec‐IFU, revealing the 2.8–5.2 micron ...

A Comprehensive Framework for Assessing Terrestrial Analogue Field Sites for Ocean Worlds

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract Field studies at terrestrial analogue sites represent an important contribution to the science of ocean worlds. The value of the science and technology investigations conducted at field analogue sites depends on the relevance of the analogue environment to the target ocean world.

Saturn's Exploration Beyond Cassini-Huygens [PDF]

open access: yes, 2009
For its beautiful rings, active atmosphere and mysterious magnetic field, Saturn is a fascinating planet. It also holds some of the keys to understanding the formation of our Solar System and the evolution of giant planets in general.

The theory of Saturn's rings [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1935
In his Adams Prize Essay for the year 1856 J. CLERK MAXWELL* took the first step towards a comprehensive theory of the unique system of rings associated with Saturn. The main theme of MAXWELLs work was to devise a model for the system of rings which could move in a steady state of motion round Saturn and which could be stable for small disturbances ...

JunoCam Observations of Io

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract During multiple Juno encounters with Io in 2023 and 2024, the spacecraft's imaging system, JunoCam, acquired approximately one hundred images of Io. These images have a range of scales down to 1 km per pixel, and covered more than half of Io's surface, including the previously poorly resolved northern and southern polar regions.
