Mission Overview

AI traffic control for debris-aware orbital routing

ASTRO-CTRL monitors live satellite traffic, predicts close-approach hazards, builds a planning lattice from projected orbital occupancy, and runs A* search so a threatened spacecraft can shift lanes before debris cuts across its path.

What Changed

From concept demo to connected mission simulation

This upgraded single-file version adds a loading sequence, a home/introduction layer, tab-based navigation, and a tighter link between the orbital scene and the planner so the A* panel represents predicted risk instead of a disconnected random map.

Intro + Mission Tabs The app now opens with an initialization screen and a landing page before the live console starts.

Predictive Planner The grid is prepared from projected traffic and hazard occupancy rather than random debris scattering.

Single-File Delivery Everything still ships in one HTML file, including the home experience, simulation, and system notes.

Mission Loop

How the avoidance flow works

1. Detect

Live collision checks and near-future convergence warnings flag at-risk satellites.

2. Project

Satellite and debris motion are projected forward into the planner grid across future ticks.

3. Search

A* explores lane/time moves to find a safe corridor through the forecast hazard field.

4. Execute

The selected satellite follows the computed avoidance route instead of remaining on its original path.

System Notes

How the A* model maps to orbit

The planner is intended as a time-expanded orbital model. Each route step pushes the mission one tick forward while allowing a limited lane shift, so the search remains interpretable and tied to the live motion of satellites and debris in the scene.

Truthful Scope

What this simulation now does better

Connected Planner State The route panel is no longer just decorative. It is built for the threatened satellite when a critical event occurs.

Integrated Reroute A successful A* run now feeds an active reroute state that changes the satellite's motion in the 3D scene.

Mission Onboarding Users enter through a loader and introduction before stepping into the live mission console.

Known Limits

What remains abstracted

No real orbital burns

Lane changes are stylized avoidance maneuvers, not full physics-based transfer calculations.

No probabilistic uncertainty

Tracked objects are treated as known exactly, without sensor noise or confidence envelopes.

Single active reroute

One avoidance plan runs at a time for clarity and to preserve performance in a single-file build.

Educational simplification

The model is explainable and visual first, even though the planning is now tied to live simulation state.
