RK4 integrator in Web Workers predicting orbital trajectories before you burn.

Strengths
  • Web Workers handle RK4 integration without blocking the main thread
  • Real NASA OEM trajectories you can actually fly alongside
  • Ephemeris data cutoff bug shows genuine physics simulation depth
Weaknesses
  • Space flight sims already exist (Kerbal, Orbiter) with deeper feature sets
  • Audience limited to orbital mechanics enthusiasts and educators
Category
Target Audience

Space enthusiasts, physics students, orbital mechanics hobbyists

Post Description

Built this 3D sandbox to fly Integrity alongside NASA OEM trajectories. Web workers run rk4 integrator to predict new path (purple) and the engine executes after burn.

Fun bug: fly longer than Moon ephemeris data cutoff May 31st to see some weird zigzag physics
