Orbital Mechanics and Astrodynamics

This reference material on Orbital Mechanics & Astrodynamics is aimed at Mechanical or Aerospace engineering undergraduate students. It covers various topics such as reference frames, the N-Body problem, two-body equations of motion, Lagrange points, orbital maneuvers including Hohmann transfers, interplanetary trajectories, and more. The associated course at the University of Connecticut recommends textbooks by authors like Roger R. Bate, Donald D. Mueller, Jerry E. White, Howard D. Curtis, Gerald R. Hintz, Kenneth R. Meyer, Daniel C. Offin, John E. Prussing, Bruce A. Conway, Ashish Tewari, David A. Vallado, and Wayne D. McClain. These textbooks delve into fundamental concepts of astrodynamics and orbital mechanics. Suggestions for improvements to this reference material are encouraged through GitHub or by contacting the author, Bryan Weber.

Go play a bit of KSP. NASA employees have stated that Kerbal Space Program has given them an intuition of orbital mechanics that a degree didn't.

And working with things that make you go _slower_ when turning on your engine to push you in the direction of travel needs intuition to even begin. Yes, once you get to the other side of the planet you are orbiting, you are going slower than if you didn't use your engine at all.

Off topic but I have never understood this quote. can anyone please explain. "In order to go fast, slow down, anybody who has learnt orbital mechanics know this"
