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. Kinetics: Modeling the Motions of Spacecraft trains your skills in topics like rigid body angular momentum and kinetic energy expression shown in a coordinate frame agnostic manner, single and dual rigid body systems tumbling without the forces of external torque, how differential gravity across a rigid body is approximated to the first order to study disturbances in both the attitude and orbital motion, and how these systems change when general momentum exchange devices are introduced.
After this course, you will be able to...
*Derive from basic angular momentum formulation the rotational equations of motion and predict and determine torque-free motion equilibria and associated stabilities
* Develop equations of motion for a rigid body with multiple spinning components and derive and apply the gravity gradient torque
* Apply the static stability conditions of a dual-spinner configuration and predict changes as momentum exchange devices are introduced
* Derive equations of motion for systems in which various momentum exchange devices are present
Please note: this is an advanced course, best suited for working engineers or students with college-level knowledge in mathematics and physics....

Interesting course with plenty of room for improvement:

1) The presentation of the course material is nice

2) There are plenty of typos in the quizzes (check forum for pointers)

3) There are some false positive answers in the quizzes (check forum for pointers)

4) There is no help offered by the course providers. No help available in the forum.

5) It would help to have the step by step answers to the quizzes available to facilitate learning from mistakes.

The best course on Space Dynamics with insightful lectures and challenging assignments. This course perfectly complements the previous course on the Kinematics of Spacecraft, and collectively provides a fundamental base for studying Attitude Control. Prof. Schaub has got exceptional skills in imparting knowledge on tough concepts fairly easily to the students. Looking forward to completing the final course on Nonlinear Attitude Control in the module!

excellent course content with knowledgeable professor. Challenging to learn and focused on both analytical theory and practical example.

It has given me the knowledge I needed to understand major topics of attitude determination. Prof. Schaub is simply superb! He teaches with such a level of passion and masters the stuff so much that you will inevitably turn out caught.

I've missed however some more numerical examples in the concept's checks as well as some simulation exercises that did exist in the Kinematics course. Moreover it has been argued that there are quite a few typos in the answers, and I can also confirm this.

In general I miss some guidance or extra assistance for your homework.

Anyway, I have enjoyed the course hugely.

I'll go for the Control one now!

Course is very good and well explained, the main problem is the lack of assistence especially when doing exercise and the final exam. In particular, only few people are doing the course and the forum is always w/o any reply, and when doing the final exam, I had to change session three times because not enough people were correctint my assignment, causing me a delay of 2 months.

Another solid course. My biggest issue with this round in the specialization is the lack of simulation assignments. There was a good deal of derivation/analytical work, but very little numerical implementation of results such as in the Kinematics course in this series.

Works for me.
