🌌 Asteroid Soundscape

A data-art experiment that transforms NASA Near-Earth Object (NEO) flyby data into sound and real-time 3D visuals.

🚀 Overview

This project explores the intersection of astronomy, sonification, and generative art through two connected tools:

• Interactive Web Visualizer (React + Three.js)
• Python Sonification Tool (MIDI generator)

Together, they create a synchronized sonic + visual soundscape of asteroid flybys.

🖥️ Interactive Web Visualizer (React + Three.js)

• Pulls real asteroid close-approach data from NASA’s NEO API
• Renders asteroids orbiting around Earth in 3D
• Reacts in real time to audio input (MP3) or MIDI
• Visual encoding:
  • Hazardous asteroids glow red
  • Non-hazardous asteroids appear blue-white
• Audio-driven effects:
  • Pulses and color shifts sync to amplitude or MIDI note events

---

🎼 Sonification Tool (Python → MIDI)

• Converts asteroid flyby data into a multitrack MIDI composition
• Maps asteroid parameters into musical features, for example:
  • Miss distance → note velocity
  • Velocity → note duration
• Hazardous asteroids trigger percussive/drum hits
• Exports MIDI files that can be loaded into any DAW:
  • Ableton, Logic, FL Studio, etc.

✨ Output

A unified audio-visual dataset performance, where asteroid flybys become:

• Motion + color in 3D space
• Rhythm + melody in MIDI-driven sound
