Isotopically Sensitive Laser-Induced Breakdown Spectroscopy (ISLIBS) — The potential to identify and analyze distributions of isotopologues would provide new opportunities in the search for biosignatures of life as part of astrobiology-related space missions.

This project aims to extend the capabilities of a planetary science laboratory instrument that combines three measurement techniques for Mars exploration: laser-induced breakdown spectroscopy, Raman spectroscopy and time-resolved laser-induced fluorescence. In particular, the laser-induced breakdown spectroscopy mode of the instrument will be extended to measure isotopes of key elements important for dating and discrimination of biological and abiological signatures.

This work will result in new knowledge on the environmental sensitivity of these techniques in environments relevant to the Earth, Moon, Mars, asteroids and comets; providing new capabilities for planetary exploration. It will also be valuable in understanding and updating the requirements for a future flight instrument.
