In particular, the past hypervelocity impact experiments suggest that sustained arcs and resulting ground faults on the power harnesses could be triggered by impacts of tiny space debris particles smaller than 1 mm which constantly impact on satellite surfaces. To perform the appropriate satellites' design for debris protection, it is important to adequately assess the risk of electrical failures on the satellite power harnesses. This presentation reports the results of hypervelocity impact experiments with more realistic impact conditions and simulated internal circuits than the past studies. In the experiments, single particles of aluminum oxide smaller than 1 mm were accelerated to nearly 7 km/s by the two-stage light gas gun of JAXA/ISAS. Our results suggest that the risk of fatal electric failure on a single line of power harness routed behind the solar array paddles is lower than that expected from the past studies.","subitem_description_type":"Other"}]},"item_4_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態:
