The Space Weather Operational Readiness Development (SWORD) center is one of three NASA space weather centers of excellence initiated in 2023 for a 5-year effort. In this talk we begin by outlining the modern challenges of space weather research, emphasizing the need to develop accurate and reliable predictive systems for a complex, non-linear, multi-scale environment that can be used in operational settings to provide actionable intelligence to end users. We then describe how the SWORD center of excellence addresses the particular challenge of predicting the space environment in low Earth orbit (LEO) with the goal of providing improved thermospheric density forecasts for satellite operators and space traffic coordination services. SWORD consists of three tracks of research: Track 1 conducts research into coupling upper atmospheric models to magnetospheric models with an emphasis on ionospheric electrodynamic specification for improved predictions of geomagnetic storm response; Track 2 focuses on developing data assimilation methods for the upper atmosphere with an emphasis on transitioning the methods to the operational JEDI framework; and Track 3 focuses on machine learning research to both improve and greatly accelerate predictive modeling of space weather drivers and the upper atmospheric environment. Together these tracks address the three challenges of modern space weather prediction research: improved physics-based modeling, data assimilation to enable predictive capability, and data-driven methods that have the potential to revolutionize how we forecast complex non-linear environmental systems.
