"The Algorithm That Lands Rockets — SpaceX GNC Explained"

On December 21st, 2015, SpaceX did something the aerospace industry had called impossible — they landed an orbital-class rocket booster, upright, on its engines. And then they did it 300 more times.
In this video, we break down the full engineering story behind how SpaceX lands Falcon 9 and Starship boosters — from the brutal physics of the inverted pendulum problem, to the real-time guidance algorithms, thrust vector control, titanium grid fins, and the legendary "suicide burn" that has zero margin for error.
🔧 What's covered:

Why a landing rocket is an unstable inverted pendulum
The GNC system: Guidance, Navigation & Control explained
Thrust Vector Control & hydraulic gimbal mechanics
The Extended Kalman Filter — how the rocket knows where it is
G-FOLD: the convex optimization algorithm that plans the landing in 50ms
Grid fins, cold gas thrusters & aerodynamic control
Starship's belly flop, flip maneuver & Mechazilla chopstick catch
Every major landing failure — and what SpaceX learned from each one

Whether you're an aerospace engineer or just someone who watches landing footage on repeat — this one's for you.
