36-mile-long starship planned for humanity's first interstellar journey

The Chrysalis Project proposes a 36-mile-long, cigar-shaped multigenerational starship designed to carry up to 2,400 people on humanity’s first interstellar journey to Alpha Centauri, specifically aiming to reach and settle on the potentially habitable exoplanet Proxima Centauri b. The one-way trip would take approximately 400 years, requiring multiple generations to live and die aboard the ship without returning to Earth. The project won the top prize in the Project Hyperion Design Competition, which focuses on conceptual designs for deep-space multigenerational vessels. The spacecraft would be built at the Earth-Moon L1 Lagrangian point to leverage nearby resources and minimize structural stresses. Its design resembles a Russian nesting doll, featuring multiple self-contained layers that form a complete ecosystem. These layers include farms, biomes for biodiversity preservation, residential areas, and community facilities such as schools and hospitals, all powered by nuclear fusion reactors. Artificial gravity would be generated through constant rotation. Population control
