This paper details our journey in designing and selecting a suitable application sandboxing mechanism for a satellite under development, with a focus on small satellites. Central to our study is the development of selection criteria for sandboxing and assessing its appropriateness for our satellite payload. We also test our approach on two already operational satellites, Suchai and SALSAT, to validate its effectiveness. These experiments highlight the practicality and efficiency of our chosen sandboxing method for real-world space systems. Our results provide insights and highlight the challenges involved in integrating application sandboxing in the space sector.
