A dual-power supply system for the Solar Close Observations and Proximity Experiments (SCOPE) mission

The Solar Close Observations and Proximity Experiments, as essential mission for studying solar activity and solar wind dynamics, fulfill highly significant scientific objectives. The power system is fundamental for the mission success, directly affecting the probe's operational efficiency and lifetime in the extreme environment near the Sun. The probe must operate in environments with extreme temperature differences, intense radiation, and complex orbital attitudes, imposing unique challenges on the power system. Traditional solar probes primarily rely on solar energy for power, but in the extreme environment near the Sun, the traditional solar panel are prone to overheating and radiation damage, increasing system complexity and reducing power reliability. This study introduces a hybrid power system dominated by thermoelectric generation and supported by the solar energy, aiming to integrate their benefits to address diverse requirements.
