Mission Nexus AI

Mission Nexus AI is a simulation-first mission operations platform built for mission-control showcases, combining a realistic spacecraft digital twin, AI-assisted planning and diagnosis, operator-approved command execution, full replay and explainability - and by design it never connects to a real spacecraft. First startup seeds everything needed for a complete demonstration: users and roles, mission configuration, seven immutable versioned runbooks, a realistic 120-tick mission history running from thermal fault through anomaly detection, AI diagnosis, operator-approved radiator deployment and rollback, a generated 240-tick forward plan, and a replay session, with the twin continuing to tick live from that point. AI diagnosis and the copilot use Llama 3.3 70B via Groq when a key is present and fall back to an explainable rule-based engine otherwise, so the system stays fully functional offline. Data lives in zero-config SQLite by default with PostgreSQL and Alembic migrations available.
