Astrodynamics is the research area concerned with the modeling, analysis, and control of the motion of natural and artificial bodies in space under the influence of gravitational and non-gravitational forces. It encompasses orbital mechanics, trajectory design and optimization, mission analysis, attitude–orbit coupling, and perturbation theory for multi-body environments. The field integrates celestial mechanics, numerical methods, optimal control, and spacecraft propulsion modeling to enable precise prediction and adjustment of trajectories for applications such as orbit insertion, station-keeping, interplanetary transfers, formation flying, and proximity operations, often requiring high-fidelity dynamical models and robust estimation techniques for navigation and guidance.
Satellites and spacecraft in the vast region between Earth and the moon and just beyond—called cislunar space—are crucial for space exploration, scientific advancement and national security. But figuring out where exactly ...

Even most rocket scientists would rather avoid hard math when they don't have to do it. So when it comes to figuring out orbits in complex three-body systems, like those in cis-lunar space, which is between Earth and the ...

For over a century, rocket propulsion has followed a simple principle; burn fuel, expel it backward, and Newton's third law pushes you forward. Since Konstantin Tsiolkovsky first formulated the rocket equation in 1903, spacecraft ...
