Daniella DellaGiustina is an assistant professor of Planetary Science at the University of Arizona's Lunar and Planetary Laboratory. She is the principal investigator for NASA’s OSIRIS-APEX mission to the asteroid Apophis and is the deputy principal investigator for NASA’s OSIRIS-REx mission, which successfully collected a sample from the surface of the asteroid Bennu and returned it to Earth on September 24, 2023. Prof. DellaGiustina specializes in investigating the surface and near-surface structure of small airless worlds across the solar system. To do so, she develops and uses remote-sensing and geophysical instruments deployed by spacecraft. She also enjoys field testing and validating instrumentation techniques at analog sites in extreme environments across our own planet. She is especially interested in water distribution throughout the solar system and how we establish its presence using remote-sensing and in-situ techniques.
