High temperature power sources can sustain a Venus lander
Recent advancements in high-temperature semiconductor materials, particularly silicon carbide (SiC) electronics and sensors, provide the necessary thermal tolerance to sustain long-duration landers on the surface of Venus.
The retrieved papers provide robust, specific evidence that high-temperature electronics and sensors (specifically silicon carbide) are being developed and tested specifically to enable extended Venus surface missions, overcoming traditional thermal limitations.
