Astrobiology & Ocean Worlds
Investigating the origins of life and searching for habitable niches across the Solar System.
Hydrothermal Vents, Prebiotic Chemistry & Biosignatures
Astrobiology bridges astrophysics, molecular biology, planetary geology, and oceanography. Key targets include Jupiter's moon Europa, Saturn's moon Enceladus (which vents saline hydrothermal plumes containing methane, hydrogen, and phosphorus into space), Titan (with liquid methane/ethane lakes and complex organic tholins), and Mars ancient sedimentary clay beds.
Breakthrough Findings
Phosphorus Detected in Enceladus Plumes
2023Analysis of Cassini Cosmic Dust Analyzer data confirmed dissolved orthophosphate in Enceladus's ocean—the final critical bio-essential element.
Hydrogen Cyanide and Complex Organics on Enceladus
2023Confirmation of powerful chemical energy pathways capable of supporting cellular metabolism.
Extremophile Survival in Mars Simulated Stratosphere
2022Fungi and endolithic cyanobacteria demonstrated viability under high UV and desiccated perchlorate conditions.
Astrobiology Methodologies
Direct flight through active ice vapor geysers using ion and neutral mass spectrometers.
Detects kinetic isotope effects characteristic of biological enzymatic carbon fixation.
Excites aromatic amino acids and polycyclic aromatic rings without destroying fragile organic structures.
