these are barely powerful enough for interstellar flight, but it would still take decades or centuries and you can forget about travelling at 1g, you still need a long coasting phase and spinning the craft for artificial gravity

>The fission-fragment rocket is a rocket engine design that directly harnesses hot nuclear fission products for thrust, as opposed to using a separate fluid as working mass. The design can, in theory, produce very high specific impulse while still being well within the abilities of current technologies.

>With exhaust velocities of 3% - 5% the speed of light and efficiencies up to 90%, the rocket should be able to achieve over 1,000,000 sec Isp.
