  • Description: The Carbon Dioxide Removal Assembly (CDRA) currently aboard the International Space Station (ISS) is a critical component of the air revitalization system in the Environmental Control and Life Support System (ECLSS). The CDRA operates by employing a zeolite material that adsorbs carbon dioxide (CO2) from the cabin air and desorbs it downstream from the cabin for further processing, ensuring CO2 levels at 2 mmHg 1 . The low thermal conductivity of zeolite reduces the heating rate of the temperature swing cycle and increases power requirements.
