The post discusses the bi-elliptic transfer maneuver, often used in spacecraft navigation to change orbits efficiently, especially in scenarios involving large inclination changes. Comments highlight the complexity and potential advantages of the bi-elliptic transfer compared to the more commonly known Hohmann transfer, which is typically used in two-body problems. Several commenters expressed the need for clearer visual representations and more mathematical depth to enhance understanding, along with a discussion on when bi-elliptic transfers might be more beneficial. There's also a light mention of application in popular space simulation games like KSP (Kerbal Space Program).
