This article is a survey paper on solving spacecraft trajectory optimization problems. The
solving process is decomposed into four key steps of mathematical modeling of the problem …

This review article aims to give a comprehensive review of periodic orbits in the circular
restricted three-body problem (CRTBP), which is a standard ideal model for the Earth-Moon …

Maintaining tracks on space objects with limited sets of observers is a critical problem, made
more urgent with exponential growth in the population of near-Earth satellites. An optimally …

The Keplerian orbital elements make up a set of parameters that uniquely describe a two-
body trajectory. Once perturbations are imposed on two-body dynamics, one often studies …

The Lunar Meteoroid Impacts Observer, or LUMIO, is a space mission concept awarded
winner of ESA's SysNova Competition “Lunar CubeSats for Exploration,” and as such it is …

Designing trajectories in dynamically complex environments is challenging and easily
becomes intractable. Recasting the problem may reduce the design time and offer global …

Periodicity of motion around the collinear libration point associated with the Elliptic
Restricted Three-Body Problem is studied. A survey of periodic solutions in the Circular …

A dynamical understanding of orbits in the Earth-Moon neighborhood that can sustain long-
term activities and trajectories that link locations of interest forms a critical foundation for the …

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 …

Upcoming missions and prospective design concepts in the Earth–Moon system extensively
leverage multi-body dynamics that may facilitate access to strategic locations or reduce …
