Story summary

Engineers at Ohio State University are developing the Centrifugal Nuclear Thermal Rocket (CNTR) using liquid uranium for efficient nuclear propulsion.
This technology aims to cut Mars travel time to six months, achieving a specific impulse of 1,800 seconds, compared to 450 seconds for chemical engines.
CNTR could enable faster missions to outer planets and Kuiper Belt objects, boosting scientific exploration.
Key challenges include stable operation and minimizing uranium loss, with a five-year timeline for solutions.
Supported by NASA, CNTR could advance space travel and facilitate permanent bases on celestial bodies.
