Maximizing Scientific Exploitation of Raman Spectroscopy With A.C.M.E. (Atmospheric Chamber for Measurements in Environment)

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

Water Transport from Enceladus to the Rings

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

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.

Ocean stratification impedes particulate transport to the plumes of Enceladus

Communications Earth & Environment
Water-vapour plumes erupting from Enceladus’ south pole provide a window into the properties of its subsurface ocean, a prime target in the search for life. However, the extent to which plume material represents conditions at Enceladus’ depths is unclear,

Saturn's Icy Moon Rhea: a Prediction for Bulk Chemical Composition and Physical Structure at the Time of the Cassini Spacecraft First Flyby

, 2005
I report a model for the formation of Saturn's family of mid-sized icy moons to coincide with the first flypast of Rhea by the Cassini Orbiter spacecraft on 26 November 2005.

TRAPPED‐S, a New Environment Model Framework for Saturn: Focus on Radiation‐Specification Model

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract As space agencies contemplate missions to the outer planets' systems and moons, entailing prolonged observations via local orbiters or potential landers, meticulous assessment of the local environment—encompassing radiation and plasma conditions—is paramount for the design of both the platform and scientific payload.

Towards Determining Biosignature Retention in Icy World Plumes

Life, 2020
With the discovery of the persistent jets of water being ejected to space from Enceladus, an understanding of the effect of the space environment on potential organisms and biosignatures in them is necessary for planning life detection missions.

Effects of Mineralogy and UV Radiation on the Detectability of Amino Acids Within the Martian Regolith: The Case for a Combined Chromatographical and Spectroscopical Approach

Journal of Geophysical Research: Planets, Volume 130, Issue 11, November 2025.
Abstract Amino acids are an extremely heterogeneous group of biomolecules essential for life on Earth. Their biosignatures are expected to be easily degraded on the Martian surface as the absence of a thick atmosphere and a magnetosphere leads to most of the solar radiation directly reaching its surface.

Petrography of phosphates in CI and CY carbonaceous chondrites

Meteoritics &Planetary Science, Volume 60, Issue 11, Page 2594-2622, November 2025.
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 ...
