Advanced Spacecraft Dynamics and Control
This Specialization on advanced spacecraft dynamcis and control is intended for experienced spacecraft dynamics and GNC engineers and researchers. It is assumed the viewer has completed the prior spacecraft dynamics specialization already. Through 3 courses we cover the topics of momentum-based attitude dynamics and control, we derive analytical methods to model complex spacecraft systems, and finally conclude with a captstone project course.

Spacecraft Dynamics and Control
Spacecraft Dynamics and Control covers three core topic areas: the description of the motion and rates of motion of rigid bodies (Kinematics), developing the equations of motion that prediction the movement of rigid bodies taking into account mass, torque, and inertia (Kinetics), and finally non-linear controls to program specific orientations and achieve precise aiming goals in three-dimensional space (Control).

Analytical Mechanics for Spacecraft Dynamics
This course is part 2 of the specialization Advanced Spacecraft Dynamics and Control. It assumes you have a strong foundation in spacecraft dynamics and control, including particle dynamics, rotating frame, rigid body kinematics and kinetics. The focus of the course is to understand key analytical mechanics methodologies to develop equations of motion in an algebraically efficient manner. The course starts by first developing D’Alembert’s principle and how the associated virtual work and virtual displacement concepts allows us to ignore non-working force terms.

Getting There and Going Beyond
Welcome to Course 2 - Getting There and Going Beyond. If you are here, you have successfully completed Course 1 (Our Place in the Cosmos) and are ready for more. There is so much more to learn in Course 2 with 40 learning objectives spread out over 5 weeks and 12 lessons. We will cover all the ways we explore space and near space from planes to rockets to satellites and humans. Week 1 - We will hit the trail with two lessons on Aeronautics. "Why is a aeronautics in a course about space?" you might be asking yourself. Well aeronautics is used in many aspects of space exploration.

Attitude Control with Momentum Exchange Devices
This course is part 1 of the specialization Advanced Spacecraft Dynamics and Control. It is a direct continuation of the Coursera specialization Spacecraft Dynamics and Control. This first course focuses on nonlinear attitude feedback control using a range of angular momentum devices. The course provides a comprehensive review of prerequisite material. Next it develops equations of motion of a spacecraft with momentum exchange devices such as reaction wheels (RWs), control momentum gyroscopes (CMGs) and variable speed control moment gyroscopes (VSCMGs).

Advanced Capstone Spacecraft Dynamics and Control Project
This capstone course is the 3rd and final course of the specialization Advanced Spacecraft Dynamics and Control. It assumes you have completed the prior courses on "Attitude Control with Momentum Exchange Devices" and "Analytical Mechanics for Spacecraft Dynamics". This project course investigates the dynamics of a complex spacecraft system where there is a rigid hub onto which a hinged panel is attached. This simulates a spacecraft with a time varying geometry. First, the three-dimensional kinematics of this system are explored.

Kinetics: Studying Spacecraft Motion
As they tumble through space, objects like spacecraft move in dynamical ways. Understanding and predicting the equations that represent that motion is critical to the safety and efficacy of spacecraft mission development.

Kinematics: Describing the Motions of Spacecraft
The movement of bodies in space (like spacecraft, satellites, and space stations) must be predicted and controlled with precision in order to ensure safety and efficacy. Kinematics is a field that develops descriptions and predictions of the motion of these bodies in 3D space.

Control of Nonlinear Spacecraft Attitude Motion
This course trains you in the skills needed to program specific orientation and achieve precise aiming goals for spacecraft moving through three dimensional space. First, we cover stability definitions of nonlinear dynamical systems, covering the difference between local and global stability. We then analyze and apply Lyapunov's Direct Method to prove these stability properties, and develop a nonlinear 3-axis attitude pointing control law using Lyapunov theory. Finally, we look at alternate feedback control laws and closed loop dynamics.
