WebFeb 14, 2024 · L2 is a point of unstable equilibrium, A craft stationed there would need many regular course corrections to maintain its position. However, there are orbits around L2 that are stable (or very nearly so). A craft in such an orbit requires far less fuel to maintain its orbit compared to a craft stationary relative to L2. WebThe Earth moves at 30 km/s so from an orbit the same as Earth's you would need a 6 km/s impulse. But it takes 11 km/s to escape the Earth's gravitational pull from LEO, so you really need only sqrt (11 2 + 6 2 ) speed from LEO. That's 12.7 km/s, and since you're already going 7.8 km/s in LEO, you need a 4.9 km/s impulse.
