Design Status of the Advanced Closed Loop System ACLS for Accommodation on the ISS
The Advanced Closed-Loop System ACLS is a regenerative life support system for closed habitats. With regenerative processes the ACLS covers the life support functions of CO2 removal, Oxygen generation and CO2 Reprocessing. ACLS will be accommodated in the Destiny module, which offers all interfaces needed for extended operations. The NASA System Maturation Team has recommended operating ACLS for a period of one year to evaluate the value of ACLS technologies for future exploration missions. The ACLS Engineering Model is in testing and the Flight Model is being manufactured and assembled. A Delta Phase-II Safety Review is held on the late allocation of ACLS to the Destiny module. The operations concept and associated ground segment infrastructure are being established. The paper summarizes the development and hardware status.
