  "abstract": "Microalgal attached cultivation circumvents gas-liquid separation issues of liquid-suspended cultivation, yet performance under reduced gravity remains unevaluated. As a proof-of-concept, we evaluated Arthrospira platensis (Spirulina) cultivation under artificial 1G, 1/6G, and microgravity ({micro}G) on the International Space Station. Spirulina expanded without cell detachment, medium floating, or component separation, with relative radial growth rates of 0.28%0.5 day-1 (1G), 0.22%0.5 day-1 (1/6G), and 0.17-0.21%0.5 day-1 ({micro}G), demonstrating feasibility in space.",
