Quantifying Mineral Abundances Using Vibrational Spectroscopy (Breitenfeld, 2024/08/28)

Full Title: Quantifying Mineral Abundances Using Vibrational Spectroscopy with Application to Planetary Surfaces: Asteroid Bennu, Mars, and the Moon Speaker: Laura B. Breitenfeld (Applicant) Abstract: An important aspect of the field of planetary science is understanding planetary surface compositions and using this information to make conclusions about solar system materials, processes, and conditions. Vibrational spectroscopy is a powerful tool in the context of planetary exploration because it provides mineral identification, chemistry, and abundance information. A complicating factor of certain spectroscopic measurements is that nonlinear mixing behaviors can influence the spectra, reducing the accuracy and precision of mineral quantification efforts. This work lays the groundwork for mid-infrared and Raman mineral quantification methodologies and their application to planetary surfaces including the asteroid Bennu, Mars and the Moon. ---------------------------------------------------------------------------------------------------------------------------------------- The Planetary Science Institute is a private, nonprofit 501(c)(3) corporation dedicated to Solar System exploration. It is headquartered in Tucson, AZ, where it was founded in 1972. In 2016 PSI established a second office in Lakewood, CO (near Denver). PSI scientists and educators are involved in numerous NASA and international missions, the study of Mars, Earth, and other planets, the Moon, asteroids, comets, interplanetary dust, impact physics, the origin of the solar system, extrasolar planet formation, dynamics, the rise of life, and other areas of research. They conduct fieldwork on all continents of the Earth to understand our planet and others. They are also actively involved around the world in science education and public outreach through school programs, children's books, popular science books, podcasts, and art.
