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.
Researchers at The University of Manchester have developed a new way to design Earth-observation satellite missions that could help protect the space environment while continuing to deliver vital data for tackling global ...
