Open Arsenal

Every Variable Accounted For.

FlightDynamics is an open, AI-native specification for launch planning, mission engineering, orbital mechanics, and space operations. It defines a structured, implementation-agnostic framework for how space missions are modeled, simulated, optimized, and executed across their full lifecycle. The specification is designed to support everything from early mission concept design through launch execution, orbital deployment, constellation management, and end-of-life disposal.

At its core, FlightDynamics is built around modular standards that describe each component of a mission as a clearly defined interface. This includes mission planning, payload definition, launch vehicle selection, trajectory design, orbital mechanics, ground operations, communications, and logistics. Each module is independent but interoperable, allowing systems built on the specification to scale from small satellite missions to complex multi-launch campaigns and mega-constellation operations.

The specification emphasizes a local-first architecture, where all core functionality can operate without reliance on external cloud services. Implementations are expected to be self-hosted by default, fully functional in offline or air-gapped environments, and optionally extendable into hybrid or federated deployments. This ensures that organizations maintain full control over their mission data, simulations, and operational workflows without vendor lock-in or mandatory third-party dependencies.

FlightDynamics also integrates AI-native design principles throughout the specification. It defines standardized interfaces for AI-assisted mission planning, optimization, risk analysis, and decision support. Every AI-driven output is required to include explainability metadata such as confidence scoring, constraints considered, and decision provenance. This ensures that automation enhances human decision-making without obscuring how conclusions are reached.

A major feature of the specification is its digital twin and simulation framework. FlightDynamics defines standardized models for simulating launch vehicles, payloads, satellites, ground systems, and entire constellations. These models support Monte Carlo simulation, failure injection, what-if analysis, and mission replay, enabling teams to validate decisions before execution.

Finally, FlightDynamics includes comprehensive standards for security, compliance, APIs, SDKs, plugin extensibility, and data interchange formats. It is designed to be fully extensible, allowing new propulsion systems, launch providers, AI models, and orbital operations concepts to be integrated without breaking compatibility. The result is a future-proof foundation for interoperable, intelligent, and autonomous space mission planning systems.
