But what if the real danger isn't leaving Earth — it's slamming back into it at 25,000 mph with a heat shield that nobody fully understands? In this video, we explore the physics of lunar reentry through Richard Feynman's signature lens — building from simple energy principles to the jaw-dropping complexity of what happens when a spacecraft hits Earth's atmosphere at 32 times the speed of sound. From ablation chemistry to the reentry corridor problem to the Arte...
