Keeping a crew alive off-Earth means managing radiation dose and the power, mass, and recycling of a life-support system. This simulator estimates total dose, a risk proxy, life-support power, consumables, and recycle rate so you can reason about crew safety and logistics together.
It connects the two things that most constrain long-duration missions — how much radiation the crew absorbs and how self-contained their life support is.
Radiation dose accumulates with exposure time and shielding, and the risk proxy scales dose into a comparable indicator. Life-support power and consumables grow with crew size and duration, while a higher recycle rate — reclaiming water and air — sharply cuts the consumables you must launch.
The tool makes the recycling leverage explicit: closing the life-support loop is often worth more than adding mass, because every kilogram of consumables recycled is a kilogram you never launch.
A multi-month deep-space leg accrues a dose that pushes the risk proxy upward unless shielding improves, while a high recycle rate keeps consumables mass modest — showing why closed-loop life support and shielding are the twin priorities for crewed missions.
No — it is an educational estimate for comparing scenarios, not a health assessment.
Reclaiming water and air reduces the consumables you must launch, which dominates resupply mass.
A simple scaling of dose into a comparable indicator, not a clinical risk number.
