ORION-X is a browser-based 3D interplanetary mission simulation built using Three.js (WebGL).
The system visualizes an Earth-to-Mars transfer trajectory with real-time animation, mission phase tracking, and cinematic space rendering.

The simulation includes:

3D Earth and Mars models

Deep space starfield environment

Curved interplanetary transfer trajectory

Animated spacecraft movement

Real-time mission phase updates

Mars orbit insertion cinematic ending

The entire project runs purely in the browser using HTML, CSS, and JavaScript

Shipped this project!

I built a cinematic space mission simulation website inspired by NASA control panels. It tracks altitude, fuel, and mission stages in real time and ends with orbit achieved and mission successful.

Through this project, I learned frontend design, GitHub deployment, project structuring, and how to turn a Python concept into a live interactive web experience.

Interplanetary Mission Simulation

ORION-X began as a vision to build a cinematic, browser-based Earth-to-Mars mission simulator using pure frontend technologies. The goal was to create a realistic space agency experience without any backend — only HTML, CSS, JavaScript, and Three.js.

The first phase focused on setting up the 3D environment. A Three.js scene, perspective camera, and WebGL renderer were configured to create a deep-space canvas. A procedural starfield with 8000 points was generated using BufferGeometry for smooth performance.

Next, Earth and Mars were created using sphere geometries and positioned across space to simulate planetary distance. Subtle rotation animations were added to give life to the scene.

The core feature was the interplanetary transfer trajectory. A Quadratic Bezier Curve was used to simulate a curved orbital path instead of a straight line, making the journey more realistic and cinematic. The rocket travels along this path using a progress-based animation system.

Mission logic was then implemented. As the spacecraft advances, the HUD updates dynamically through mission phases:
• Leaving Earth Orbit
• Deep Space Cruise
• Mars Approach
• Mars Orbit Insertion

A live distance counter increases with progress, enhancing the simulation feel.

Finally, a cinematic success overlay was added. When the rocket reaches Mars, a full-screen mission completion sequence appears, signaling successful orbit insertion.

ORION-X demonstrates how advanced 3D simulations can be built entirely in the browser using WebGL — transforming simple web technologies into an immersive space mission experience. 🚀🌌
