Asteroids, often called "fossils of the solar system," are remnants from its formation that offer clues about planetary origins and the potential beginnings of life. Dr. Neil Farber, Solar System Ambassador for NASA's Jet Propulsion Laboratory, explains that some, known as near-Earth objects, pose impact risks—though large, dangerous collisions are rare—and NASA's Near-Earth Object Surveyor mission aims to detect and track them to inform planetary defense strategies. Asteroids may also hold resources, such as metals or water, that could one day support space exploration, though current technology limits mining feasibility. Recent missions like OSIRIS-REx, Lucy, and Psyche are expanding our understanding of asteroid composition, history, and diversity, with findings including evidence of past water, amino acids, and nucleotide bases—key building blocks of life—raising intriguing questions about whether asteroids helped seed life on Earth.
