Meet Chrysalis: The starship that could take 2,400 humans to Alpha Centauri, nearest star system in 400 years

Chrysalis spacecraft: A spaceship capable of transporting 2,400 humans on a multigenerational, one-way trip to Alpha Centauri, the nearest star system to our own, got the first prize in the Project Hyperion Design Competition, as per a report. The theoretical vessel, named 'Chrysalis', would take approximately 400 years to cover its 25-trillion-mile journey, according to the engineers who designed it, as reported by Livescience.

What Is Chrysalis and How Far Will It Travel?

Although no one living today would ever step foot on its terminus, the design conceives of a future in which generations would live and die upon a spaceship, a moving civilization in transit, as it would take 400 years to reach Alpha Centauri, according to the report.

Chrysalis designers envisioned it not only as a vessel, but as a sustaining society, according to the report. The travelers would be pioneers of another sort, children born in space who had never known Earth, and will house several generations of people until it enters the star system, where it could shuttle them to the surface of the planet Proxima Centuri b, an Earth-size exoplanet that is thought to be potentially habitable, as reported by Livescience.

Training for Life in Space: Preparing the First Generation

To train the people boarding the ship, the first generation would spend 70 to 80 years in seclusion in Antarctica as the environment would ensure psychological wellbeing, according to the report.

What’s Inside Chrysalis?

The vessel will potentially be 36 miles (58 kilometers) long, and Chrysalis will be designed as a gigantic Russian nesting doll, with encasing habitats that envelop a core, as per the Livescience report. These encasings would house all of the necessities of human existence: homes, schools, parks, farms, and even forests, where every segment would be powered by theoretical nuclear fusion generators, according to the report.

At the center of the ship are shuttles and all the communication equipment, the heart of this mobile world, as per the report. The layer closest to the core is expected to be used to produce food, everything from crops and fungi to animals and insects, keeping a delicately balanced ecosystem, as per the Livescience report.

The second level would accommodate communal living, with libraries, hospitals, and space for study and play, according to the report. The residential level follows, planned with ventilation and climate control for each home, as per the Livescience report. Beyond that are the areas for industry, recycling, and production, as per the report. The outer shell would contain the gear, raw materials, and machinery, probably maintained by robots, according the Livescience.

Chrysalis would only be sustainable for a population of about 1,500 individuals, and births would be planned accordingly, as per the report.

The project engineers said that, those responsible for the ship's governance would collaborate with artificial intelligence, "allowing for resilience of the whole social system, better knowledge transfer between the different generations of inhabitants and a deeper vision of the overall dynamics of the Chrysalis spaceship complex," as quoted in the Livescience report.

However, the entire plan is purely hypothetical, as some of the required technology, like commercial nuclear fusion reactors, doesn't yet exist, but projects like this one can still add to the existing knowledge base and help engineers improve upcoming designs, as reported by Livescience.
