For part one, follow this link: there we answer the question “how to stay in orbit”. In this post, we want to figure out how to change the orbit we are in and, in particular, how to get into orbit.
How to change our orbit
Let us assume we are in an elliptical orbit, and that we change our velocity with an impulse (instantaneous change of velocity) along the same velocity vector we had previously when we are at perigee (this is just for simplicity, to fix a special point). What happens?Continue reading “Orbital mechanics – Part 2”
