Space debris impact (i.e. hypervelocity impact) generates not only mechanical phenomena such as generations of a crater and secondary debris but also electrical ones such as plasma generation, radiofrequency emission, impact flash, and variation in electrical potential of the impacted target. We conducted hypervelocity impact experiments using the two-stage light gas gun installed at ISAS/JAXA. We used a high-speed video camera, a photodetector, a strike camera spectroscopy, plasma probes, and microwave receivers to measure electrical phenomena induced by hypervelocity impact at the same time. Plasma from hypervelocity impact is generated during dozens of microseconds and may trigger to an electrical discharge of spacecraft. For instance, an impact on the solar paddle or the power harness of satellites may generate a sustained discharge via plasma interaction and a short-circuit path is created in the worst case. In terms of the radiofrequency emission, the microwave emission from hypervelocity impact have been confirmed. The microwave with intermitted pulses with a periodic time of several nanoseconds is emitted until several milliseconds. The mechanism of the microwave emission is still unknown, but we expect the energy estimation of space debris impact using microwave remotely as one of the application techniques.
