A 3-minute orientation to the framework, the twelve systems, and the simulators. The fastest way to understand what this site is and how to use it.
// 01 / What this is
A working model of how humans
actually survive in space.
The rockets are on the way. Mars in the 2030s, lunar bases sooner, deep-space transit after that. Most of the public conversation is about the vehicles. Almost nothing is published about whether the people inside them survive. Or how.
Human Space Support is a working model of that question. Twelve interconnected subsystems: food, water, air, body, fracture, decay, awakening, continuity, decisions, skills, cascade, unknowns. They are modeled together because they break together. Stress one and the others react. Real numbers, real thresholds, public data.
The site is in beta. The numbers are model outputs, not measurements. They are being stress-tested for accuracy as the framework matures.
// 02 / The twelve systems
Twelve systems. When one fails,
it affects the other eleven.
(Sometimes catastrophically.)
Most analyses isolate each subsystem and study it alone. This site treats them as a single coupled model, because that's how they actually fail. Every system has its own page with the math, the limits, and the failure modes.
If you want the overview first, read The Hard Limits. It's the page that explains how the twelve subsystems lock together and where the bright lines are.
// 03 / The simulators
Three tools for running
the framework yourself.
Reading the math is one thing. Running it is another. These three simulators let you actually test the framework with your own inputs.
Scenario Engine
Pick a crew size, a duration, a destination, and the mitigation levers. The engine runs the math across all twelve subsystems and tells you exactly where the pressure lands and what fails first.
Run a scenario →Cascade Simulator
Pick a single failure on Day X. Watch it propagate through the other eleven subsystems in real time. The clearest demonstration that these things are coupled, not independent.
Trigger a failure →Mission Generator
The inverse of the scenario engine. Tell it the goal — "send 25 people to Mars for 18 months" — and it solves backwards for the minimum viable mission profile.
