A nuclear-powered rocket could cut Mars commutes in half.
How a nuclear powered rocket should work, in a nutshell, is that a fission reactor using uranium would heat up extremely cold liquid hydrogen, propelling hot gas out of a nozzle to generate thrust.
If all goes to plan, the first DRACO test could see a nuclear-powered rocket in space as early as 2027. NASA itself is investing a chunky $300 million, with the overall value of the award totaling nearly $500 million.Mars is at perigee That sluggishness owes to the inefficiency of chemically powered rockets, which can't carry enough fuel to power the engines much longer after launch.
