Small space debris impact that induces discharge can trigger disturbance of a spacecraft, which is a big threat to the safety of it. Research on this effect has already been carried out, but due to the limit of the facilities the research is also restricted. Since the primary cause of small space debris impact that induces discharge is to induce the plasma, similar to the laser inducing the plasma, this paper tries to simulate the space debris impact inducing discharge using a laser-induced discharge method. The analysis and experimental results are given, and they prove that this method is reliable.
