Why NUCLEAR ROCKETS Sound Easy… Until Physics Shows Up - Feynman’s Warning

#nuclearrockets, #nuclearpropulsion, #nuclearthermalrocket, #ntr, #nerva, #roverprogram, #nuclearengine, Most people assume nuclear rockets would be vastly superior to chemical ones. The energy density of uranium is roughly 2 million times greater than rocket fuel. So why haven’t we flown one? The answer isn’t politics or funding — it’s physics itself, taxing every advantage at every step until the “2 million times more energy” becomes “roughly twice the exhaust velocity.” That’s still useful. But it’s not the revolution you’d expect. In this video, we explore the real physics behind nuclear thermal rockets through the lens of Richard Feynman’s teaching style, drawing on concepts from his legendary approach to explaining nature’s stubborn constraints. From the Tsiolkovsky rocket equation to the melting point of graphite, from hydrogen corrosion to cryogenic boiloff, we trace exactly where the promise collides with reality. 📚 SOURCES: “Space Nuclear Propulsion for Human Mars Exploration” — National Academies of Sciences, Engineering, and Medicine (2021) “Rover Nuclear Rocket Engine Program: Overview of Rover Engine Tests” — J.L.
