How to Use This Calculator

Enter the number of crew members and daily CO2 production per person in kg.
Set the target cabin CO2 partial pressure (typically < 0.5% for long-duration missions).
Input the scrubber type (LiOH, CDRA, Sabatier) and rated efficiency.
Review the required scrubber capacity in kg CO2 per day and consumable mass per mission day.
Calculate total LiOH or sorbent mass for mission duration and margin.
