AbstractSpacecraft payloads are multifunctional and provide a high degree of technicality. Because of these, the power consumption of spacecraft increases. Therefore, the bus voltage must be raised to mitigate the loss during transmission just as it is done for infrastructures on the Earth. Unlike on Earth, 100V is already considered as a high voltage in space, which can lead to arcing because of the interaction of the charged spacecraft with the ambient plasma. The arcing risk is particularly high on solar array. A way of solving problems related to the high voltage technology will be the key for the next generation space technologies such as larger space stations, space hotels, and so on. The authors performed two demonstration experiments in near earth orbit (low earth orbit and polar earth orbit) for testing solutions to the aforementioned problem. First, the data from HORYU-2, nano-satellite developed by Kyushu Institute of Technology, were analyzed. HORYU-2 mission consists in generating 300V without causing arcing, and contributing to the practical development of the next generation space systems. Second, a degradation test by arcs was performed on solar cells onboard the International Space Station by using PASCAL (Primary Arc effect Solar Cell At Leo), which was included MISSE-8 (Material on the International space station Experiment-8). In this paper, the high voltage and the arcing mitigation feasibility from data analysis results in near earth orbit are presented.
