An interactive 3D visualization of the Artemis II mission — humanity's first crewed lunar flyby in over 50 years. Follow Orion's complete journey from launch to splashdown in real time.

The spacecraft's trajectory is derived from NASA's official ephemeris data (OEM format, J2000 reference frame), and the Moon's position is fetched live from the JPL Horizons API. Everything renders in a real-time 3D scene directly in your browser.

A fullstack monorepo with a React + Three.js frontend and a Hono API backend. Built through vibe coding with Claude and Gemini.
