Spacecraft Dynamics and Numerical Simulation with Python

Understanding how satellites and spacecraft move through space requires a solid grasp of both orbital mechanics and computational physics. This text-based course bridges the gap between theoretical space dynamics and practical computer simulation. You will transition from understanding basic gravitational laws to writing clean, structured Python code that simulates complex orbital trajectories and attitude maneuvers, gaining the confidence to model space missions using modern numerical methods. What you'll learn: - Understand foundational concepts of orbital mechanics, Keplerian elements, and coordinate reference frames. - Apply numerical integration methods, such as Runge-Kutta algorithms, to solve differential equations of motion. - Model two-body and multi-body gravitational systems using modern Python libraries like NumPy and SciPy. - Simulate spacecraft attitude dynamics, rotational kinematics, and basic stabilization techniques. - Analyze orbital perturbations, including atmospheric drag and the Earth's J2 oblateness effect. The course begins with essential terminology, coordinate systems, and physics fundamentals before moving into step-by-step numerical implementation. You will explore practical simulation scenarios, analyzing how forces shape a spacecraft's path and orientation in space through written explanations and code walkthroughs. This course is designed for aspiring aerospace engineers, physics students, and programmers interested in space technology, with no prior experience in orbital mechanics required.
