ARES Kevin Righter

Biography

Kevin Righter is a planetary scientist and curator for both the Antarctic meteorites and Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) asteroid samples within the Astromaterials Research and Exploration Science (ARES) Division at the Johnson Space Center. Before coming to Johnson, Righter was a research associate in the department of planetary sciences at the University of Arizona in Tucson. Righter currently uses the application of igneous petrology, experimental petrology and geochemical analysis to understand core formation, the origin of the Earth and Moon as well as differentiated and chondritic meteorites and the role of volatiles in the origin of basaltic magmatism. Righter’s research and curation activities help ascertain the content, origin and evolution of the solar system and the potential of life elsewhere.
