Web15 jul. 2015 · Step 1: Munar approach. Sharpy's advice covers this this pretty well. Fine-tuning your orbit for low munar periapsis doesn't require much dV from your rocket if you do it early when you're still a long distance from the Mun. (Reason for wanting the low periapsis: to save fuel, it's an efficient use of dV for the next step.) Step 2: Orbit Mun. WebThe flight path angle (φ) is the angle between the direction of velocity and the perpendicular to the radial direction, so it is zero at periapsis and tends to 90 degrees at infinity. tan ⁡ …
