Their Project Orion achieved breakthrough thrust-to-weight ratios and specific impulse values that chemical rockets still can’t match, but the engineers were constrained by 1950s materials that couldn’t withstand the extreme conditions. Today’s advances in carbon nanotube composites, refractory metal alloys, and ultra-high-temperature ceramics are finally providing the materials foundation that could make Dyson’s atomic dreams reality.
