@kenshirriff This is a fantastic writeup, basically all of the ~1% of curious people in the space industry will end up reading it. As is often the case, the asides are many of my favorite parts; it feels very American to be specifically concerned about the environmental impact of your Global Thermonuclear War Machine’s cold gas thruster fuel.

On footnote 8 there is a typo, “3000 km, even times the altitude”.
