Would love to see content on orbital mechanics as space becomes more and more important in everyday life. Much of the foundation is in other lectures, but an astrodynamics library that approaches orbital mechanics in an organized fashion and focuses on the convergence of the math and science and unique topics (e.g. classical orbital elements, state vectors providing those values from ground observations, rendezvous of two bodies and launch to get to certain orbits, maneuver in space and delta-v, etc) would be a great learning resource! Thanks for the consideration.
