Abstract:
The contemporary space domain is defined by rapid asset deployment and a growing reliance on space-based capabilities for national security and economic stability. However, spacecraft face persistent threats from a complex space environment, and current mission assurance efforts are hindered by the use of siloed, single-physics analysis tools. This isolated approach fails to capture coupled, synergistic effects—such as the interplay between radiation transport, material degradation, and electrostatic charging—leaving blind spots that can lead to unforeseen system failures. To address this critical capability gap, we propose the conceptual architecture for the Spacecraft Comprehensive Orbital Resilience Engine (Space-CORE), an advanced framework designed to provide a holistic understanding of spacecraft-environment interactions from initial design through end-of-life. Rather than a monolithic application, Space-CORE is envisioned as a federated software orchestration layer. It is designed to augment and unify trusted, expert-validated US simulation packages (such as NASCAP-2k, MCNP6, and IRENE) through a common data architecture and standardized interfaces. This enables a powerful new workflow where the output of one physics simulation serves as a validated input for another. For example, a radiation transport model could dynamically update a deep dielectric material’s properties, which are subsequently fed into a charging simulation to assess real-time changes in electrostatic discharge risk. The Space-CORE framework will provide “cradle-to-grave” benefits, including rapid multi-fidelity spacecraft design, proactive anomaly mitigation, and powerful forensic “digital autopsy” capabilities. Most critically, Space-CORE provides a revolutionary capability for “self” Space Domain Awareness (SDA). By precisely modeling the impact of space weather on a specific spacecraft, operators can rapidly diagnose on-orbit anomalies, confidently ruling the environment in or out as a causal factor. This paper outlines the Space-CORE conceptual architecture and serves as a call for community engagement to chart a path toward its realization.
