Aeorspace class check, GMAT NASA orbits class

So while I’ve been sitting on my hands think of a new class to teach, rather than going through busy syntax of a language, is anyone here interested learning about Orbital Dynamics using tools made by NASA that’s open and free to the public? If there’s anyone who’d like to learn from about the General Mission Analyst Tool(GMAT), it is a tool that lets you design, create, propagate, and optimize orbits in 2D and 3D of various spacecraft. If you’ve seen a launch of a rocket on video and see it cut to a simulation, it was probably done GMAT or STK. If you wanna see what it does. https://www.youtube.com/watch?v=cT2bzzp8P1U

Sounds interesting. I know of the tool, but very little about it.
