The Gateway and CAPSTONE spacecraft are planned to orbit the Moon in a Near Rectilinear Halo Orbit (NRHO) that experiences a 9:2 resonance with the lunar synodic period. Disturbances applied to spacecraft in this NRHO must be corrected to achieve a reasonable lifetime in orbit. This investigation explores the variations between a spacecraft operating under nominal orbit maintenance and the baseline NRHO. The effects of perturbations on an unmaintained spacecraft are examined, with a focus on the time to depart the NRHO. Finally, the costs of correcting disturbances of varying magnitudes are computed using a simple but robust orbit maintenance algorithm.
