Design an interstellar 'generation ship' to spend decades among the stars with Project Hyperion competition

Human technology has allowed us to extend the scope of our curiosity beyond the confines of our home world and into the solar system. But it's not hard to imagine that one day humans will want to venture further, perhaps towards a star in our galactic vicinity that might host a rocky, watery world not unlike Earth.

Getting there, however, is complicated. Even if human technology reaches a point in the near future where we could create a propulsion system that could get a spaceship within 10% the speed of light (which is orders of magnitude faster than what is currently possible), a journey to a nearby star hosting a potentially habitable world could take decades or hundreds of years at best. Given these limitations, a number of scientists and science fiction authors have pondered the feasibility of something called a "generation ship." A generation ship is a hypothetical spacecraft capable of sustaining human inhabitants for multiple generations as they make the vast journey to a nearby star system.

A new design competition, dubbed Project Hyperion, is calling for submissions for the design of a crewed interstellar generation ship. The project is part of study that is aiming to provide an assessment of the feasibility of crewed interstellar flight using current and near-future technologies, and hopes to inform future research and technology development as well as informing the public about logistics and potential of interstellar travel.

Rather than focusing on the design of the propulsion system, or structural design of the ship, researchers are specifically interested in answering what an ideal space habitat architecture and social system would look like for such a journey.

For the competition, a team of at least one architectural designer, one engineer, and one social scientist is tasked with designing the habitat of a generation ship, including its architecture, and system of societal organization.

The constraints applications must adhere to are as follows:

  • The duration for the hypothetical mission is 250 Earth years from launch to arrival at the destination.
  • The target destination is a rocky planet with an artificial ecosystem created by a precursor probe.
  • The generation ship/habitat generates Earth equivalent gravity via rotation.
  • The habitat will provide atmospheric conditions similar to Earth.
  • The habitat shall protect its inhabitants from radiation and possible impacts.
  • The ship should be able to accommodate 1000 +-500 people over the entire trip duration.

What are some factors that designers should be mindful of? While no human has spent such long periods of time in space, science fiction authors have been exploring what types of challenges such a project could face, in addition, human beings have been living and working in space for some time. What have we learned?

  • Privacy: How will the design of the ship ensure inhabitants can achieve privacy given they are going to be confined to a ship with hundreds of people?
  • Mental health: How will the design of the habit mimic Earth's natural environment?
  • Conflict resolution: How will the design of the habitat minimize potential conflict, and how will the social system deal with possible unethical behavior?
  • Intimacy: How will the design of the ship allow for intimacy between inhabitants?
  • Social Hierarchy: How will social roles be allocated/enforced?
  • Connection to Earth: How will inhabitants maintain their connection to Earth?

Designs will be evaluated on their architectural considerations, such as how the living space will function for its inhabitants, as well as its aesthetic properties. They will also be evaluated on the technical details, such as how the essential physical needs of the inhabitants are met (e.g. food, water, waste recycling). And lastly they will be evaluated on their social planning, such as what cultural value system will the society adopt, and how this system will mitigate against issues the society is likely to come up against.

    A fascinating idea of course. My only objection would not be technical but moral. Is it fair to expect generations of humans to live confined on a ship this size and live their lives without either seeing Earth or their destination planet? I think generational starships are immoral and such technology should only be used if and once there is some kind of hibernation technology for the crew so that they arrive without having used up too much of their lives. This applies also in the case of much extended life spans in the future; who could bear the boredom of such a trip?

    Yes, totally agree. It would be immoral to have a child on such a ship. There are problems with suspended animation that might be difficult to overcome. The naturally occuring phosphorus in our bones emits radiation that degrades the DNA. I have read of a predicted 1,000 year limit.

    I am not so sure that I agree with the morality case made above.

    It really depends on how the spacecraft is designed. If it is just a box with life support plumbing and no windows, it would be very confining, mentally. But if it is a living ecosystem, with room to move around, tasks to perform for survival, and observatories to let people observe where they are and where they are headed (with appropriate telescopic infrastructure), I am not seeing this as being much different the living on Easter Island before Captain Cook got there.

    Confining? - definitely! But, it would be the only "real world" that successive generations ever knew. There would be psychological adaptation - and cultural evolution.

    The real question in my mind would be how humans react to the absolute certainty that their little ecosystem has a limited viable population. Could they accept that, and stay one cohesive culture, or would there be competition for dominance of different subcultures with different ideas - as has developed on our much larger multi-generational space craft that we have named "Earth"?

    A very interesting subject and discussion. If you want to read a very recent fictional take on a generational starship see Anthony Doerr's Cloud Cuckoo Land. This novel features a generation starship called the Argos which is flying its crew of humans to a nearby star at 10% of the speed of light. The trip is scheduled to take around 600 years. At the time in the novel, they're around 7 decades into the trip and quite a few children have been birthed onboard the Argos. It's very interesting how Mr. Doerr handles most of the issues discussed in this article on his fictional Argos. It is especially interesting how he handles the issue of disclosing to the children that the trip is going to take 600 years and none of them are ever going to live to see to the planet that is the trip's destination. The novel is actually way larger than just the Argos, spanning eight centuries and with five main characters, only one of which is on the Argos. I consider it an excellent read and one of Mr. Doerr's best novels. Note: Anthony Doerr won the Pulitzer Prize in fiction for his novel All the Light We Cannot See. Cloud Cuckoo Land is his first novel published after the release of All the Light We Cannot See.
