☄️ Low-Earth-Orbit Decay Lab: Atmospheric Drag, Solar Activity and Re-entry Lifetime

Watch a satellite sink through the thermosphere: tune ballistic coefficient, solar flux F10.7 and geomagnetic storms, and see decay rate, speed-up, station-keeping delta-v and re-entry lifetime from orbit-averaged drag, checked against a direct RK4 integration. Unlike the existing debris and re-entry sims, this one models the orbit-decay phase itself.
