In understanding the space environments, the space physics study has widely utilized the in-situ measurement. However, it is well-known that the local plasma will be disturbed in the process of plasma-object interactions resulting in the influence on the plasma measurements. In this study, for the application in the instrumented rocket missions, an unstructured Particle-In-Cell model is employed for the numerical investigations. It shows that, behind the traveling conductor, the background magnetic field, the traveling speed, and the object volume can all affect the formation of plasma wakes.
