This paper presents a qualitative scoping literature review that investigates the potential of using multifunctional self-healing composites for satellite applications. As the global demand for satellites to operate in harsh space environments or extended periods of time (including thermal cycling, UV radiation, vacuum exposure and micrometeoroids impacts), improving the structural integrity and reliability of materials has become a critical engineering challenge. Carbon fibre reinforced polymers *(CFRPs) while widely used, remain susceptible to microcracking and increasing environmental degradation. This review evaluates current self-healing mechanisms, comparing intrinsic and extrinsic systems while considering how self-healing can be integrated with other functionalities such as thermal management, electrical conductivity, structural integrity and radiation resistance. The literature indicates that using extrinsic microcapsules is the technological approach currently available due to their high healing efficiencies and passive activation. Conversely, intrinsic systems offer the potential for repeated healing cycles but remain limited by complex chemistry and challenges associated with implementation in aerospacegrade composites. Across the literature, multifunctionality presents itself as the primary challenge rather than self-healing alone; integrating self-healing alongside structural and other performance metrics introduce significant engineering trade-offs with improvements in healing efficiency often reducing mechanical integrity, environmental durability and practical manufacturing. Furthermore, most existing research remains confined to laboratory-scale testing with limited validation under orbital conditions. Overall, this paper concludes that multifunctional self-healing composite materials offer significant potential to extend the longevity of spacecraft operating in-orbit while enhancing their structural durability. This paper prompts and calls for future research to navigate the balance between autonomous repair and environmental and structural demands of long-term satellite missions.
