About

Justin Green is a researcher specializing in guidance, navigation, and control (GNC) systems for aerospace vehicles, with a particular focus on powered descent and landing technologies. His most notable contribution is the development of adaptive control allocation methods that enable powered descent vehicles to tolerate engine failures in real time—a critical capability for future human and robotic space missions. His 2018 paper, "Adaptive Control Allocation for Powered Descent Vehicles," has garnered 2 citations and lays foundational groundwork for resilient flight control under actuator faults. Green’s work directly addresses the challenge of maintaining vehicle stability and mission success when hardware failures occur mid-descent, a problem of paramount importance for NASA’s Artemis program and commercial lunar landers. By integrating real-time failure detection with control reallocation, his research enhances the safety and reliability of planetary landing systems. Though early in his citation impact, Green’s contributions are strategically vital, positioning him as an emerging authority in fault-tolerant GNC for space exploration.
