In an ambitious and visionary project, a groundbreaking study and design competition produced a conceptual model for a spaceship capable of taking humans on a one-way, 250-year journey to Alpha Centauri, the closest star system to Earth. This study, part of the global Project Hyperion competition, has captured the imaginations of scientists, engineers, and architects. The winning design, named Chrysalis, envisions a self-sustaining vessel capable of housing 1,000 passengers over multiple generations.
The Self-Sustaining Ship Designed to Leave Earth Forever
At a staggering 36 miles (58 kilometers) in length, Chrysalis features a sophisticated array of biome ecosystems that are integral to long-term survival. Inside, you’ll find everything from food production rooms and libraries to parks, multi-storey living areas, schools, and even sports complexes. One of the most striking features is the 130-meter-high “cosmos dome”. With its large glass panels, this dome allows the passengers to float freely in space while looking out at the stars.
The ship would be powered by nuclear fusion reactors, a technology that could provide reliable energy for the spacecraft over its multi-generational journey. Concentric cylinders rotating at high speed would generate artificial gravity, allowing the passengers to live and work in a simulated Earth-like environment.
Life on the “Generation Ship”
The ship is divided into several “shells,” each with a specific function to ensure the well-being of its passengers. One shell would house agriculture and biomes—critical spaces designed to recreate Earth’s diverse environments, including tropical forests, boreal forests, and dry scrublands. These biomes are essential for preparing the inhabitants to eventually colonize a new planet, specifically Proxima Centauri b, a planet located four light years from Earth.
Another key feature is its genetic bank, which would store seeds, embryos, and DNA from all species aboard the ship. This precaution is designed to preserve Earth’s biodiversity for future generations. The spacecraft would also use a closed-loop system for water and nutrient recycling, ensuring that resources are carefully managed for the journey ahead.
Though plant-based food production would dominate on the ship, there would be limited space for animals, primarily for aesthetic and diversity purposes, not food production. Protein could be synthetically produced, mirroring today’s lab-grown protein technologies. These sustainable practices would be crucial for surviving a 250-year journey in deep space.
How This Ship Will Keep 1,000 People Alive?
The Chrysalis design isn’t just about survival—it’s about creating a thriving community in the vast expanse of space. The spacecraft’s third shell would be dedicated to living quarters, with 20 sectors containing “module houses” for each of the 1,000 inhabitants. These modular homes would offer personal space while still fostering a sense of unity and shared purpose. Inhabitants could even move between sectors as they wish, creating a fluid and dynamic living environment.
Communal spaces are also a vital part of life aboard Chrysalis. Parks, libraries, and recreation areas would offer passengers the chance to relax and maintain their mental well-being during the long journey. Additionally, large windows and walls could act as screens, simulating landscapes from Earth and creating a sense of connection to their distant home planet.
The design of Chrysalis emphasizes social cohesion, with a family structure that allows individuals to live with their chosen family members, but without rigid ethical requirements. Parents who have children could live together, but they would also have the freedom to decide if they wish to relocate to other sectors during the mission.
Observing the Cosmos from the Cosmos Dome
Perhaps the most fascinating aspect of life aboard Chrysalis is the cosmos dome, which serves as the only space through which inhabitants can observe the external environment of deep space.
This dramatic, glass-panel dome would offer a panoramic view of the stars, providing a visual connection to the universe far beyond the ship. It’s in the cosmos dome where the “Chrysalis Plenary Council” would gather each year, bringing all passengers together for an annual meeting. Interestingly, the dome would face backwards, toward the ship’s origin—the Sun and Earth.
This design was recently awarded first place in the Project Hyperion competition, which tasked teams of scientists, engineers, and architects with conceptualizing a realistic “generation ship” that could support human life for centuries.
