PROJECT ASTRAHOLON

Technical Blueprint for Next-Gen Space Colonization

Mission Overview

Project Astraholon represents humanity's most ambitious extraterrestrial habitat, designed as a permanent, self-sustaining colony at Earth-Moon L4 Lagrange point. This rotating megastructure combines cutting-edge engineering with ecological balance to support long-term human settlement in deep space.
