Dante Lauretta

Dante Lauretta is an American planetary scientist and cosmochemist known for leading the NASA mission OSIRIS-REx to return samples from the near-Earth asteroid 101955 Bennu. He is a professor at the University of Arizona and director of the Lunar and Planetary Laboratory, with research focused on asteroid composition, organic chemistry in the early Solar System, and sample curation. Lauretta has contributed to multiple space missions, laboratory studies of meteorites, and public outreach through media appearances and authored works.

Early life and education

Lauretta was born in Tucson, Arizona, and raised with connections to the American Southwest and institutions such as Tucson and Pima County. He completed undergraduate study at the University of Arizona and earned graduate degrees at the University of New Mexico and the University of Arizona. During his doctoral work he engaged with laboratories and researchers affiliated with the NASA Johnson Space Center, the Smithsonian Institution, and the American Museum of Natural History. His early mentors and collaborators included scientists associated with the Meteoritical Society, the American Geophysical Union, and investigators from the Jet Propulsion Laboratory.

Academic and research career

Lauretta joined the faculty of the University of Arizona's Lunar and Planetary Laboratory, participating in research networks that include the National Aeronautics and Space Administration, the European Space Agency, and the National Science Foundation. He has led teams studying meteorite petrology linked to collections at the Smithsonian National Museum of Natural History, Antarctic meteorite programs coordinated with the United States Antarctic Program, and spectroscopic surveys tied to observatories like the Kitt Peak National Observatory and Mauna Kea Observatories. Lauretta has contributed to sample analysis techniques used by groups at the NASA Johnson Space Center, the Jet Propulsion Laboratory, and the California Institute of Technology, collaborating with investigators from the Massachusetts Institute of Technology, Harvard University, and Stanford University. His laboratory studies address organics in carbonaceous chondrites, isotopic systems relevant to the formation of the Solar System, and mineralogical processes comparable to findings from the Hayabusa and Stardust missions.

OSIRIS-REx mission and asteroid sample-return

As Principal Investigator of OSIRIS-REx, Lauretta led a mission managed by NASA and executed by the Lockheed Martin team, with scientific partnerships involving the Canadian Space Agency and institutions such as the University of Arizona and the Jet Propulsion Laboratory. The mission rendezvoused with asteroid 101955 Bennu, performed remote sensing campaigns using instruments comparable to those on the NEAR Shoemaker and Dawn missions, and executed a sample acquisition maneuver inspired by techniques from Hayabusa2. OSIRIS-REx characterized Bennu's surface using a payload integrating spectrometers, cameras, and LIDAR similar in heritage to instruments developed at the Jet Propulsion Laboratory, NASA Goddard Space Flight Center, and university laboratories. Under Lauretta's leadership the mission completed sample collection, curation protocols interfacing with the NASA Johnson Space Center's Astromaterials Acquisition and Curation Office, and plans for sample distribution to teams at the Smithsonian Institution, Caltech, Massachusetts Institute of Technology, and international partners including investigators from the European Space Agency and the Japan Aerospace Exploration Agency. The mission's objectives connect to broader programs such as the New Frontiers program and scientific goals outlined by the National Academies of Sciences, Engineering, and Medicine.

Awards and honors

Lauretta's work has been recognized by awards and honors from organizations including the NASA Exceptional Achievement Medal, the Meteoritical Society, and university-level distinctions from the University of Arizona. His leadership on OSIRIS-REx has garnered citations in publications associated with the American Astronomical Society, the American Geophysical Union, and the European Geosciences Union. He has been invited to speak at conferences such as the Lunar and Planetary Science Conference and meetings sponsored by the International Astronomical Union and the National Academy of Sciences.

Selected publications and media appearances

Lauretta is an author and co-author on peer-reviewed papers in journals tied to the American Geophysical Union, the European Geosciences Union, and publishers associated with the American Association for the Advancement of Science. He has contributed chapters to books and edited volumes used by researchers at institutions including Caltech, the Massachusetts Institute of Technology, and the Smithsonian Institution. In public media he has appeared in documentaries and interviews broadcast by outlets such as the National Geographic Society, the Smithsonian Channel, PBS, and science programs associated with the American Museum of Natural History and the Royal Institution. He also participates in outreach through collaborations with museums and planetary science organizations like the Planetary Society and educational initiatives funded by the National Science Foundation.
