What technology enables rovers like Curiosity and Perseverance to function on Mars?

Answer

Multi-Mission Radioisotope Thermoelectric Generators (MMRTGs) using plutonium-238

Nuclear power remains indispensable for sustained surface operations on celestial bodies like Mars, particularly due to the environmental challenges presented there. Rovers such as Curiosity and Perseverance are equipped with Multi-Mission Radioisotope Thermoelectric Generators (MMRTGs). These devices function by converting the consistent thermal energy produced by the decay of plutonium-238 directly into electricity. This capability is vital because it allows the rovers to maintain operational temperatures and run essential systems through the intense, frigid Martian nights and during periods of heavy dust accumulation, conditions which would severely impede or halt solar-powered vehicles.
