DELTA-SIERRA TOOL — MARS

Mars settlement oxygen-demand calculator

Turn a chosen crew oxygen-consumption assumption into daily demand, nominal stock and margin.

Essential answer

The prefilled rate is an editable educational example. Real architecture must separate metabolism, leakage, EVA, fire response, production, storage and emergency reserve.

Every value below can be changed. Prefilled values are educational examples, not an official NASA architecture.

Calculator

m_O₂ = Population × chosen rate × duration × (1 + margin)
Edit the values and run the calculation.

Method and limits

The calculator deliberately shows intermediate operations. Keep units visible, state the calculation boundary and distinguish a chosen assumption from measured performance.

A numerical result does not prove an architecture is feasible: availability, maintenance, contaminants, storage, redundancy and failure cases still require separate sizing.

The prefilled values are documented in a versioned dataset. They are editable educational examples, not an official mission architecture.
