“…The mass density of the type-II superconductor YBCO is a good first order approximation, leading to an estimation of 5 g cm -3 for the mass density of the particles. 13 Further, assuming that the layer of particles is on the order to 10 -5 m thick, the sail assembly load factor for a particle cloud sail is 50 g m -2 . Although this number is still in a higher range of currently estimated sail assembly loading factors for traditional solar sails, it does indicate that a particle cloud solar sail may be able to perform comparably to its thin-film counterparts.…”

Traditional solar sail architectures involve large, thin, reflective membranes stretched across lightweight structural elements, a design that has many well-documented engineering challenges. This paper evaluates an alternative, "fractionated" solar sail in which the sail itself is composed of small discrete particles held in place by superconductive flux-pinning forces. This analysis investigates two candidate particulate solar sail architectures: a particle-cloud sail and an integrated payload sail. It emphasizes design aspects of the particles, the macroscopic structure, deployment methods, possible control mechanisms, and performance metrics. The sail loading factor for each design is found to be 50 g m -2 and 90 g m -2 for the particle cloud sail and integrated payload sail respectively. The examination concludes with a discussion of major challenges and potential applications for each design.
