We present the main findings of a dynamical mapping performed in the LowEarth Orbit region. The results were obtained by propagating an extended gridof initial conditions, considering two different epochs and area-to-massratios, by means of a singly averaged numerical propagator. It turns out thatdynamical resonances associated with high-degree geopotential harmonics,lunisolar perturbations and solar radiation pressure can open naturaldeorbiting highways. For area-to-mass ratios typical of the orbiting intactobjects, these corridors can be exploited only in combination with the actionexerted by the atmospheric drag. For satellites equipped with an areaaugmentation device, we show the boundary of application of the drag, and wherethe solar radiation pressure can be exploited.
