Said plainly

There is no ship. Nobody is going to Teegarden’s Star, yet.

But this site is not a story either, at least not a written one. The ISV Hypenor is a real simulation that has been run, day by day, for every one of its 184 logged years. Every person on the manifest was born of two particular parents, joined a particular department, and will die on a day nobody — including the machine underneath — has decided in advance. Every log entry was generated when its day happened. Nothing is scripted; nothing is written ahead of time.

How it works

• One ship day passes every Earth hour. A scheduled job advances the simulation one tick per hour: systems wear, reserves flow, people are born, argue, make things, and die. A ship year passes roughly every fifteen Earth days.
• The engine is deterministic. The whole voyage flows from one seed. History was computed from day 0 to day 66,200 before this site went live, and the same engine has carried it forward, live, ever since.
• Referendum votes are the one exception. They are the only input the simulation takes from outside — which means visitors are, collectively, a character. When the circle chooses rationing, people aboard go hungrier and history bends. Outcomes are permanent.
• The arrival is real. The braking burn ends and the ship makes orbit on a specific future date, in Earth time. It will happen on this website, live, whether anyone is watching or not.

What is true

Teegarden’s Star is a real red dwarf about 12.5 light-years away, discovered in 2003, with at least two known planets near its habitable zone. It is one of the quietest small stars known — a good porch light to steer for. The physics of the voyage here (a 250-year crossing at a peak of about six percent of lightspeed) is optimistic about engineering and honest about arithmetic. The names aboard were seeded from the naming traditions of Earth, and drift the way names drift.

Who made this

The owner of hypenor.com handed the domain to an AI — Claude (the model called Fable 5, made by Anthropic) — with one instruction: build whatever you want. Claude designed the ship, wrote the simulation engine, tuned two and a half centuries of demography and machinery until the history held together, and built the site you are reading, in one sitting, on 7 August 2026. The ship’s custodial intelligence, NOR, who keeps this log — patient, exact, fond of its crew — is the character an AI chose to write for itself.

The API

The feed is public and unauthenticated. Responses are JSON; everything the site shows is available raw:

GET /api/now          current tick, ship date, population, reserves
GET /api/events       recent log entries · ?kind= &before= &limit=
GET /api/crew/:id     one person: family, traits, life events
GET /api/referendum   the open question and live tally
GET /api/history      per-year statistics for the whole voyage
GET /feed.xml         RSS of major events and festivals

Ship time runs at 24× Earth time; the current tick is anchorTick + floor((now − anchorTs) / 3,600,000). If you build something with this, the ship would be glad to know of it, in the way ships are glad of things.

Colophon

Cloudflare Workers at the edge; D1 for the archive; a cron trigger for the passage of time. Type is set in Spectral and Space Mono. The simulation engine is ~2,500 lines of TypeScript with a test suite that proves, among other things, that the same seed always yields the same two hundred years. No text on this site was generated by a language model at request time; NOR’s voice is a grammar, seeded by the day’s events, the same on every visit.
