A spacecraft which will use nuclear electric propulsion to power its interplanetary journey. Offering higher speeds from far less fuel than standard rockets, the technology could be key to unlocking exploration of the outer Solar System and enabling human space settlements closer by. Nuclear electric propulsion (NEP) relies on fission to generate heat, which gets converted to electricity via a gas turbine. This power, in turn, ionizes a gas propellant into a plasma that shoots continuously out of thrusters. Just tens of kilograms of uranium-235 fuel and thousands of kilograms of propellant can be enough for an interplanetary journey. The 12kW reactor is to be fuelled by high-assay low-enriched uranium (HALEU), using uranium dioxide fuel encased in a boron carbide radiation shield.
