About

D. E. Highsmith is a leading figure in astrodynamics and deep-space navigation, best known for their pivotal contributions to NASA’s OSIRIS-REx mission. As a key architect of the spacecraft’s flight dynamics and navigation design, Highsmith developed the precise trajectory and guidance algorithms that enabled the historic rendezvous with asteroid Bennu, sample collection, and safe return. Their seminal 2018 paper, “OSIRIS-REx Flight Dynamics and Navigation Design” (88 citations), remains a foundational reference for mission planners and researchers tackling the challenges of small-body exploration. Highsmith’s work has directly shaped how autonomous navigation and hazard avoidance are implemented in low-gravity environments, influencing subsequent missions like Psyche and Dragonfly. With a career spanning over two decades, they have also contributed to Mars rover entry, descent, and landing systems. Their impact is measured not only in citations but in the successful execution of one of NASA’s most complex sample-return missions, demonstrating an exceptional ability to translate theoretical orbital mechanics into operational reality. Highsmith continues to advance the field through mentorship and innovative navigation solutions for next-generation planetary exploration.
