June 7, 2025, China: Researchers from the University of Science and Technology of China (USTC) have developed innovative solutions for power generation and energy storage on Mars.
The team proposes using the Martian atmosphere as a medium for power generation, increasing efficiency by 20% and maximum power density by 14% compared to using rare gases. This approach leverages local resources for sustainable energy.
They also introduced the "Mars battery," utilizing atmospheric components as reactive fuel. This battery can combine electrical, light, and thermal energy, offering a self-sufficient energy solution for Martian exploration. Tests show the battery functions steadily even at 0°C.
This technology significantly reduces the overall weight of the energy system and enables in-situ energy acquisition. This is crucial for China's future Mars missions, including the Tianwen-3 probe, scheduled for launch around 2028.
