Demonstrated potential health benefits for crew members within the cabin.

Abstract

The Japan Aerospace Exploration Agency (JAXA) has been developing the Carbon Dioxide Removal System (CDRS) for the Lunar Gateway International Habitation module (I-HAB). CDRS provides the essential function of removing CO2 that could harm the crew's health in the closed cabin. It is an amine-based regenerative system that absorbs CO2 and vents it to space under a preliminary design phase. This report presents the current status of design and development including parametric studies on the CO2 removal rate using a CDRS breadboard model and following cabin CO2 analysis to achieve a preliminary design solution.
