Electrodynamic tethers (EDTs) are long, conductive wires or tapes deployed from spacecraft that
enable energy generation and propellantless thrust when moving in a planetary magnetic field. This
work extends a planar Earth–Moon Circular Restricted Three-Body Problem (CR3BP) model by
including the EDT Lorentz force term with a controllable in-plane tether tilt relative to the local
radial direction. Using dense grids of initial conditions, both local (around the five Lagrange points)
and global (Earth–Moon synodic frame) escape-time and exit-basin stability maps are constructed
to quantify how sustained EDT actuation influences stability patterns and transport pathways.
Consistent with the expected results from the CR3BP, it is found that the large stable regions of the
Earth–Moon system are not greatly affected by the EDT forcing. However, the exit patterns near
the Earth display modified escape-time structures and altered transport routes. The addition of
the Lorentz acceleration to the equations of motion enables adjustment of the tether current and
tilt to target residence times near the collinear Lagrange points L1 and L2 and to manage leakage
at the periphery of the triangular L4 and L5 points.
