Formation of Water-rich Giant Planet Satellites at Decretion Disk Ice Lines

The Planetary Science Journal
The volatile budgets of giant planet satellites are critical to unraveling the origin of their building blocks within the circumplanetary disks that hosted them.

Exploring Enceladus's Interior Structure Using Electromagnetic Induction

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Electromagnetic (EM) sounding can constrain the electrical structure of Enceladus and, in turn, the salinity of its ocean and the porosity, fluid content, and thermal state of its hydrothermally active core. Here, we assess the feasibility of EM sounding at Enceladus using both global (orbiter) and local (lander) EM induction transfer ...

New Saturnian satellites

Eos, Transactions American Geophysical Union, 1982
Four, and possibly as many as six, new satellites of Saturn have been found as a result of data from the Voyager 2 encounter with the planet in August 1981. The discoveries bring the number of Saturnian satellites to between 21 and 23. The two ‘possible’ satellites were seen in only one observation each, so their orbits are not yet confirmed.The ...

The PHESAT95 catalogue of observations of the mutual events of the Saturnian satellites [PDF]

Astronomy and Astrophysics, 2001
In 1994-1996 the Sun and the Earth passed through the equatorial plane of Saturn and therefore through the orbital planes of its main satellites. During this period, phenomena involving seven of these satellites were observed. Light curves of eclipses by Saturn and of mutual eclipses and occultations were recorded by the observers of the international ...

The Potential for Organic Synthesis in the Ocean of Enceladus

The Astrophysical Journal
The Cassini spacecraft detected a soup of organics in the plume of Saturn’s moon Enceladus. Those compounds could provide building blocks for the potential emergence or sustenance of microbial life in Enceladus’ subsurface ocean. However, the sources and

Shallow Impact Craters Suggest Titan Stores Methane in an Insulating Clathrate Crust

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Multiple lines of evidence suggest that a methane‐clathrate crustal layer exists in Titan. However, we have not directly confirmed the existence or thickness of this hypothesized layer, a potentially important methane reservoir. Here, we model impact crater formation and subsequent viscoelastic evolution in Titan's ice shell with methane ...

A JWST Study of CO2 on the Satellites of Saturn

The Planetary Science Journal
Solid state CO _2 has been detected throughout the outer solar system, even at temperatures where crystalline CO _2 is unstable, requiring that the CO _2 be trapped in a separate host material. The Saturnian satellites provide an ideal laboratory for the

Comprehensive Characterization of Water Group Ion Composition and Distributions in Saturn's Magnetosphere With Cassini Plasma Spectrometer Data

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Saturn's magnetosphere is continuously supplied with neutrals from the Enceladus plume and the icy rings, which undergo ionization and charge‐exchange to form a complex water‐group plasma environment. While the Cassini Plasma Spectrometer (CAPS) instrument has provided extensive compositional information, detailed separation of individual ...

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.

Modeling Ganymede's Surface Charging in Preparation for the JUICE Mission

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract The European Space Agency's (ESA) JUICE mission (JUpiter ICy moons Explorer) is en route to the Jovian system to characterize Ganymede's subsurface ocean. Determining the ocean's conductivity and depth requires precise measurements of its induced magnetic field at the position of JUICE.
