We propose a ‘system-of-systems’—an integrated web of SpWx stations and state-of-the-art modeling facilities to enable a transformative advance in Space Weather nowcasting and forecasting. The Space Weather Aggregated Network of Systems (SWANS) will enable space situational awareness for end-users invested in spaceflight operations, infrastructure risk mitigation, and future human endeavors in space exploration while profoundly transforming Heliophysics research by 2050 or earlier.
