Global Model of Atmospheric Chlorate on Earth

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 5, 16 March 2025.
Abstract Naturally occurring chlorate (ClO3−) has been observed on Earth and potentially plays important roles in hydrology and mineralogy on Mars. However, natural sources of chlorate are uncertain. Here, we quantify the importance of atmospheric sources of chlorate.

Genomic characterization and radiation tolerance of Naganishia kalamii sp. nov. and Cystobasidium onofrii sp. nov. from Mars 2020 mission assembly facilities

IMA Fungus, 2023
During the construction and assembly of the Mars 2020 mission components at two different NASA cleanrooms, several fungal strains were isolated. Based on their colony morphology, two strains that showed yeast-like appearance were further characterized ...

Investigating Impacts of Amino Acids on the Structural Stability of Anionic Biomembranes

ChemSystemsChem, Volume 7, Issue 2, March 2025.
Glycine and lysine interact with the anionic membrane composed of POPC and POPG (1 : 1). Lysine partitions into the membrane and induces structural alterations, while the membrane remains impermeable to it. In contrast, glycine causes no physicochemical damage and permeates through the membrane.

Interpretable Machine Learning Biosignature Detection From Ocean Worlds Analogue CO2 Isotopologue Data

Earth and Space Science, Volume 12, Issue 3, March 2025.
Abstract Future missions to icy ocean worlds (OW) such as Europa and Enceladus will evaluate the habitability and potential for biosignatures on these worlds. These missions will benefit from autonomous science and machine learning (ML) methods to process high volumes of data and prioritize signals of interest for the first available downlink.

Morphology and Distribution of Bubble‐Supported Microbial Mats From Ice‐Covered Antarctic Lakes

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 3, March 2025.
Abstract Gas bubbles directly influence the macromorphology of benthic microbial mats resulting in preservable biosedimentary structures. This study characterizes the morphology and distribution of microbial mats growing in gas‐supersaturated, perennially ice‐covered lakes Fryxell, Joyce, and Hoare of the McMurdo Dry Valleys of Antarctica ...

Discovery of Naturally Etched Fission Tracks and Alpha-Recoil Tracks in Submarine Glasses: Reevaluation of a Putative Biosignature for Earth and Mars

International Journal of Geophysics, 2016
Over the last two decades, conspicuously “biogenic-looking” corrosion microtextures have been found to occur globally within volcanic glass of the in situ oceanic crust, ophiolites, and greenstone belts dating back to ~3.5 Ga.

Rapid Automated Mapping of Clouds on Titan With Instance Segmentation

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 1, March 2025.
Abstract Despite widespread adoption of deep learning models to address a variety of computer vision tasks, planetary science has yet to see extensive utilization of such tools to address its unique problems. On Titan, the largest moon of Saturn, tracking seasonal trends and weather patterns of clouds provides crucial insights into one of the most ...
