🎓 Orbital Mechanics

A spacecraft in Low Earth Orbit travels at ~7.8 km/s. To reach orbit, a rocket must accelerate past the Kármán line (100 km) while building enough horizontal velocity to balance gravity — achieving orbital equilibrium. This simulator uses a 4th-order Runge-Kutta integrator with J2 oblateness perturbation derived from NASA's GMAT.
