Developed a real-time, web-based 3D visualization of active NASA satellite orbits using live Two-Line Element (TLE) data. Built with satellite.js for orbital propagation and Three.js for rendering, the viewer computes orbital positions in real time. Features interactive controls, dynamic orbit trails, realistic Earth motion, and a kiosk display mode for public installations. Deployed on the NASA website and featured in the NASA Headquarters Earth Information Center exhibit.
