Concordiatra A Harmonious Pilgrimage to the Stars

A comprehensive design study for a multi-generational interstellar colony ship. 20,000 people depart Mars L5 orbit in the 2130s. 3,700 years and 150+ generations later, their descendants arrive at Proxima Centauri.

Concordiatra is a single rotating cylinder—13.6 km long and 3.6 km in diameter—constructed from asteroid-mined high-nickel taenite at Mars L5. Rotating at 0.705 RPM, it provides a full 1.0g of artificial gravity at its rim, where 113 square kilometers of interior surface area support residential communities, agricultural terraces, industrial zones, research facilities, and the transit core that runs its full length.

The name fuses Concordia (Latin: harmony through diversity) with Yatra (Sanskrit: purposeful spiritual journey). Pronounced kon-KOR-dee-AH-tra, it embodies the mission's core principle: humanity can create harmony not by eliminating differences, but by learning to travel together across the vast distances between stars.
