The dynamical environment in the close-proximity of small celestial bodies is characterized
by a very weak and irregular gravity field. In this low-acceleration deep-space environment …

Incorporating quasi-periodic orbits into the preliminary design process offers a wide range of
options to meet mission constraints and address the challenges in a complex trade space. In …
