I was that kid who wanted real spaceflight science, so I built what I didn’t have. Free module on rocket propulsion, orbital mechanics, and mass budgets for kids who want the REAL STUFF

The books either talked to 6 year olds or assumed a physics degree. Nothing in between. I never forgot that gap. So I built it. Free link here: Don't forget to look up
