Frontiers in Astronomy and Space SciencesEnceladus, one of Saturn’s moons, is considered one of the most promising places in the solar system to find life. The Cassini mission discovered organic-rich water plumes from Enceladus’s subsurface ocean, prompting new lander mission planning.

Using Tidally‐Driven Elastic Strains to Infer Regional Variations in Crustal Thickness at Enceladus
Geophysical Research Letters, 2023 Constraining the spatial variability of the thickness of the ice shell of Enceladus (i.e., the crust) is central to our understanding of the internal dynamics and evolution of this small Saturnian moon.

Petrography of phosphates in CI and CY carbonaceous chondrites
Meteoritics &Planetary Science, EarlyView.Abstract Phosphate minerals are significant carriers of volatiles (e.g., OH) and halogens in chondritic material; however, their origin in most groups of carbonaceous chondrites remains poorly characterized. We have determined the abundance, morphology, texture, and composition of phosphate grains in aqueously altered CI chondrites and in hydrated and ...

Cassini CAPS‐ELS Observations of Low‐Energy Electron Beams Within Enceladus Mid‐Latitude Flux Tubes
Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract The electrodynamic interaction between Saturn's magnetosphere and Enceladus accelerates electrons along magnetic field lines. These electrons propagate inside magnetic flux tubes connecting the moon to the giant planet, generating distinctive auroral hiss and auroral footprint signatures, both previously observed by the Cassini spacecraft.

Spatial Distribution of Glycine and Aspartic Acid in Rapidly Frozen Brines Relevant to Enceladus
The Planetary Science Journal, 2023 Saturn’s moon Enceladus harbors a global, subsurface liquid ocean beneath an icy crust that actively erupts water jets from fissures in its south pole. Data returned from the Cassini mission have identified salts and organic matter within these ejected ...

Flux Tube Properties and Interchange Instabilities in Jupiter's Middle Magnetosphere
Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.Abstract In Jupiter's magnetosphere, the outward transport of Io‐genic plasma and the planetward injection of energetic particles are facilitated by flux tube interchange motion driven by centrifugal instabilities. Flux tube content and entropy are two competing key quantities that determine the behavior of the system.

Journal of Raman Spectroscopy, Volume 56, Issue 11, Page 1394-1403, November 2025.Simulated planetary gas detection using the A.C.M.E. chamber and a novel hollow‐core fiber Raman sensor. Controlled atmospheric mixtures were used to evaluate the sensor’s performance, demonstrating its capability to detect gases such as CO₂, O₂, and N₂. The results support the applicability of the HCF‐based Raman sensor in future planetary exploration

Evidence of Gaia Enceladus Experiencing at Least Two Passages around the Milky Way
The Astrophysical Journal LettersOne of the major recent breakthroughs has been the discovery of the last major merger to happen in the history of the Milky Way. Around 10 Gyr ago, the galaxy Gaia Enceladus with an estimated ∼10% of the Milky Way mass, fell into the potential of our ...

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 ...

A Compact Ion‐Electron Plasma Camera Spectrometer With an Instantaneous Hemispheric Field of View
Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.Abstract Using additive manufacturing and a selective metalization technique, we have developed a compact ion/electron plasma camera based on the donut topology. With its instantaneous field of view of 2πsr $2{\uppi }\mathrm{s}\mathrm{r}$, it eliminates the need for electrostatic deflectors.
