3 Nuclear Drives Revolution Space : Space Science And Technology
The three nuclear-driven propulsion concepts - fusion-driven plasma thrust, nuclear-laser directed-energy, and radioisotope-thermoelectric assisted thrust - promise to halve interplanetary travel times and slash mission costs. The fusion-driven experiment cut the projected Mars transit from 260 days to 138 days, a 47% reduction, and demonstrated sub-sonic plasma acceleration without toxic
