Abstract Collinear Earth–Moon libration points have emerged as locations with immediate applications. These libration point orbits are inherently unstable and must be maintained regularly which constrains operations and maneuver locations. Stationkeeping is challenging due to relatively short time scales for divergence, effects of large orbital eccentricity of the secondary body, and third-body perturbations. Using the Acceleration Reconnection and Turbulence and Electrodynamics of the Moon's Interaction with the Sun (ARTEMIS) mission orbit as a platform, the fundamental behavior of the trajectories is explored using Poincaré maps in the circular restricted three-body problem. Operational stationkeeping results obtained using the Optimal Continuation Strategy are presented and compared to orbit stability information generated from mode analysis based in dynamical systems theory.

    Highlights ► Operational demonstration of Earth–Moon libration point orbit stationkeeping. ► ARTEMIS mission orbits analyzed using Poincaré maps in the CR3B problem. ► Optimal Continuation Strategy used to maintain ARTEMIS Earth–Moon L1 and L2 orbits. ► Optimized operational stationkeeping maneuvers explored using Floquet mode analysis.
