- Artist’s concept: A notional spacecraft with a high-power agile plasma thruster is powered by novel kilowatt-level radiovoltaics (cells that turn radiation directly into electricity). The use of radiovoltaics would enable space vehicles to travel to highly radioactive regions of space that are inaccessible to spacecraft otherwise powered by delicate solar arrays.
