Abstract: Solid propellant systems enable challenging lunar and planetary exploration missions even in small size, but there are concerns about cracks inside the propellant in a low-temperature environment.In this study, 3D X-ray CT imaging was performed while cooling the simulated composite propellant with liquid nitrogen.The effect of cooling and shrinkage on the particle filling structure was examined by visualizing the three-dimensional distribution of voids and changes in the filling structure, as well as by tracking individual particles that moved due to temperature changes and visualizing their displacement．
