Resumen:

The nonlinear astrodynamics in the cislunar space beyond the geosynchronous belt (xGEO), encompassing secular, resonant, chaotic, close-encounter, and manifold dynamics, is dramatically different than the weakly perturbed Keplerian approach used for over a half century for the detection and tracking of objects near Earth. Yet, to date, only the relatively short timescale dynamics of libration-point orbits (LPOs) and and their associated invariant manifolds have been partially coupled with the cardinal questions and problems posed by cislunar space situational awareness (SSA). Here, we uncover the foundational dynamics in the entire cislunar regime, including lunar mean-motion resonances (MMRs) and secular resonances, which have hitherto not been rigorously investigated, to holistically improve SSA capabilities beyond the traditional geocentric domains.
