Very nice and useful project for people who don't have the physics background. Some suggestions to add: - You should add a note at the escape velocity calculation that it's equal to sqrt(2) * the circular orbit velocity at that altitude. - You could include the derivation of the gravitational potential energy in there as a side note. - A section on the Oberth effect would be very nice to see (and easy to explain with the energies taken care of already). - Some visuals would be nice, like some diagrams of the various types of orbits (based on eccentricity). I'm suggesting these just in case you haven't considered them already (i know it's work-in-progress, of course). Very nice initiative and i'm looking forward to seeing more. I'll definitely be keeping an eye on this EDIT: And if i can help in any way, i would be glad to.
