Astrogeologist

An Astrogeologist is a geoscientist who studies the geology of celestial bodies such as planets, moons, asteroids, and comets. They analyze surface features, rock compositions, and geological processes beyond Earth to understand the history, structure, and evolution of these bodies. Astrogeologists contribute to planetary exploration missions by interpreting remote sensing data, conducting field analog studies on Earth, and helping design scientific instruments for space probes.

Career Description

Astrogeologists investigate the geological characteristics of extraterrestrial environments to unravel the processes shaping planets and other celestial bodies. They study surface morphology, mineralogy, tectonics, volcanism, and impact cratering through satellite imagery, rover data, and sample analysis. Their research helps determine planetary habitability, locate resources for future missions, and understand the solar system’s formation and evolution. Astrogeologists collaborate with astronomers, planetary scientists, chemists, and engineers to plan and execute space missions, develop geological models, and interpret mission data.
