Near Rectilinear Halo Orbits (NRHOs), a subset of the L1 and L2 halo orbit families, are
strong candidates for a future inhabited facility in cis-lunar space. Characteristics of the …

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 …

Fragmentation events are the most common source of artificial debris in space. Such events
can happen for multiple reasons, ranging from collisions with active or inactive objects to …

In the near future, several space applications in the Earth-Moon system may require a
spacecraft to hold a stable motion, but the transfer trajectory infrastructure to access such …

A critical first step towards achieving the goal of a far-reaching human presence in space
within the 21st century is the creation of a long-term crewed habitat in cislunar space, well …

The orbital dynamics in the three-body system is a classical problem in the field of
astrodynamics. It has rich theoretical and engineering significance, and have played an …

Midcourse correction design is key to space transfers in the cislunar space. Autonomous
guidance has garnered significant attention for its promise to decrease the dependence on …

The stable near rectilinear halo orbits (NRHOs) and distant retrograde orbits (DROs) are
both considered as potential parking orbits for cis-lunar stations. Transfer orbits between …

As demonstrated by ongoing concept designs and the recent ARTEMIS mission, there is,
currently, significant interest in exploiting three-body dynamics in the design of trajectories …

The stable distant retrograde orbits (DROs) around the Moon are considered as potential
parking orbits for cislunar stations that are important facilities in cislunar space. Transfer …
