Interplanetary Vessel · Earth — Titan — Enceladus — Earth

Twelve people. Fifteen years. No rescue, and hours to ask Earth a question.

A ship you operate by procedure, not by reflex. Every gauge is fed by one causal model of the vessel; every warning names its price, and the few hard refusals name their reason; and the flight plan was flown in GMAT, NASA's open-source mission analysis tool, before it was ever flown here.

You sit at her consoles and run her for fifteen years. Every warning names its price and lets you do it anyway. There is no undo.

Not a navigation bar — four arguments you may choose to enter. Each owns its own figures, so a number appears on the page that is responsible for it and nowhere else.

One causal model drives the whole vessel. A lever moved in one bay moves the ship and another bay's numbers, because there is only one graph underneath and every console reads from it. Nothing rolls dice — every unpredictability is a deterministic process you can learn to read.

Every element in the mass ledger sums to the ledger's own TOTAL row, or this page does not build.

She carries craft, and the craft are how the science actually gets done. Nothing lands on Enceladus by accident: a plume transit is worked from the K-6, and Titan is flown rather than driven, because Titan has an atmosphere thick enough and gravity low enough that rotors are the cheapest way to move.

This is the game: you sit here and run her. Live telemetry, the camera bank, the ship's state — every reading tied back to the same causal model as the vessel above.
