Environmental control and life support system evolution
Space station growth scenarios were reviewed and environmental control and life support system (ECLSS) growth requirements and ECLSS-driven constraints derived. A broad range of advanced ECLSS technologies were evaluated for their potential of being developed for flight use. Based on these evaluations the 'hooks and scars' needed to accommodate subsystems based on the technologies were defined with particular attention to the fluid electrical interface requirements.
