In both cases, the sample collection spacecraft would rely on a radioisotope thermoelectric generator, or RTG, instead of solar ... He was referring to the agency's Perseverance rover, which ...
The lander will also employ a nuclear power source — a radioisotope thermoelectric generator (RTG), as used by Curiosity and Perseverance — rather than solar panels, as previously planned.
