The generation ship is not broken when the engine stops working, but when individuals fail, it breaks down. It is that assumption which lies at the heart of Chrysalis, a 36-mile long ship notion which will carry 1,000 humans on a one-way trip to another star, and which will be constructed on the notion that sociology could be as critical to the ship as shielding or thrust.
Chrysalis emerged as the winner in Project Hyperion, a design competition challenge in generational ship, the work of the Initiative to Interstellar Studies. In contrast to several other interstellar literature, Hyperion entrusts newcomers with the ship being a functional settlement: government, education, food production, health and conflict resolution were to be engineered in the same way as pressure vessels, power buses and so on. The short focused on a voyage in lifetimes, not months, which required a place that could remain self-consistent as a society, even as systems grew old, skills moved and Earth faded into a distant radio memory.
The target world of the competition is typically the rocky planet Proxima Centauri b. The thing is that the presence of “habitable zone” does not mean that there is a guarantee of the existence of life. According to NASA, the planet is listed as either within or close to the habitable zone of its star, and such important aspects are not known, such as whether it is tidally bound and whether it has an atmosphere. In a non-returning mission, those unknowns transform the destination into optional surface project instead of the home of promise, the ship must be habitable like a real home even when they have arrived.
Chrysalis alleviates that fact by considering the onboard community as a closed-loop system with failure modes all on its own. The quality of housing is structured around multi-family instead of atomised single cabin, which is a physical decision primarily aimed at redistributing care work and lessening brittle isolation dynamics experienced with small-group confinement. The choice is biased towards Antarctic-style screening, in the form of remote overwintering as a proxy to long separation, due to the fact that the design presupposes that the interpersonal stability and mental health should be designed in advance, as opposed to fixed during the next stage. The menu is not vegetarian in ideology: the number of inputs needed to produce plant-based calories is lower, biosecurity is also easier, and the system of waste management is also simpler in a closed habitat.
That decision is projected onto a more general technical fact: such a ship as Chrysalis breathes or dies by bioregenerative life support. Closed ecological research has long been interested in regenerative air, water and food cycles what engineers refer to as controlled ecological life-support systems since, in the case of voyages across generations, “bring everything” fails. Food production is not the only purpose of plant growth and it becomes atmospheric management, water recovery, transpiration, condensation, and even partial counteraction of chemical offgassing since vegetation captures some volatile substances. These modules of agriculture are not luxuries, but infrastructure, as basic as pressure control, in that frame.
The organizers of Project Hyperion suggested that the link between the ship and the society is inseparable. According to Andreas Hein: The technological nature of the ship, including propulsion and the life support has been researched extensively, with the technological nature of the ship and the on board society usually being viewed as two distinct concerns.
Chrysalis drives the most difficult question to the extreme: the approval of people who have not yet been born. Volunteering can be done by the initial passengers. Their children get a predetermined world, its laws and its course. It is that that renders education, governance legitimacy, reproductive planning, right to dissent engineering demands, since social fracture turns out to be a life-support emergency, in absence of resupply, no evacuation and no alternative habitat available in the vicinity.
In the meantime, Chrysalis is merely a blueprint a kind of “existence proof,” which incites the human community as hardware. Its greatest service can be this reversal, the way to another star does not start with the improved engine diagram, but the inhabited, service-able, morally consistent society that is capable of continuing to operate without the stars beyond it ever becoming any nearer, at least not in the short term.
