The Japan Aerospace Exploration Agency (JAXA) is developing a CO2 removal system to strengthen core life-support technologies for future crewed space missions. The ISS demonstrator of the CO2 removal system (DRCS) is being developed as one of the activities demonstrating Gateway's CO2 removal system (CDRS) and is scheduled to be launched in FY2024. This paper describes the features of the DRCS, the results of the performance tests of the DRCS Proto Flight Model, and the progress of the validation tests.
