[1] DellaGiustina is most known for her contributions to the field of planetary sciences, particularly in the area of asteroid remote sensing and spacecraft instrument development.
Her research focuses on the study of asteroids and moons, as well as the use of remote sensing and seismic techniques to investigate planetary surfaces, structures, and dynamics.
While investigating the formation and degradation patterns on the surface of asteroid Bennu, she co-led a study that discovered variations in boulders with differing albedo and physical characteristics, suggesting that the boulder's ages range from the time of the parent body's formation and subsequent disruption to the recent production in near-Earth space.
[6] With regards to her research into the reflectance and colour variations observed on Bennu's surface, her work indicated that the heterogeneity of its primordial materials, coupled with varying exposure times, are responsible for the observed variations, and also implied that the progression of space weathering follows a distinct trend rather than a predictable red-to-blue or blue-to-red pattern.
[7] She is also responsible for the discovery of material from asteroid Vesta implanted on Bennu's surface, likely from an impact on its parent body.
