Resonances and chaos in medium Earth orbits. Since my PhD, I investigated the dynamical structure of medium Earth orbits (MEOs), with a particular focus on the role of third-body resonances induced by the Moon and the Sun. Inspired by the work of Todd Ely in the late 90's (Purdue University), this research aimed to characterize the complex dynamical environment of MEOs through both analytical and numerical approaches. I developed a comprehensive dynamical description of the MEO region, identifying the dominant resonant mechanisms and their interactions. This work led to the construction of an atlas of orbital stability, highlighting regions of long-term regular motion as well as pathways to chaotic behavior. Particular attention was given to the mechanisms that trigger Hamiltonian chaos, including resonance overlap and secular–resonant couplings.
Beyond fundamental theory, my research addressed real-world applications in space operations. I explored how naturally occurring chaotic dynamics can be exploited as “dynamical corridors” to enable passive and fuel-efficient orbital disposal. These results contribute to sustainable spaceflight strategies by leveraging intrinsic dynamical instabilities to facilitate end-of-life deorbiting in the MEO region.
