SUBDOMAINS:

1. Air Revitalization: The overarching function of this area is to maintain a safe and habitable atmosphere within a spacecraft, surface vehicle, or habitat.
2. Water Recovery and Management: This area provides a safe and reliable supply of potable water to meet crew consumption and operational needs.
3. Waste Management: The objective of this area is to safeguard crew health, increase safety and performance, recover resources, and protect planetary surfaces, all while decreasing mission costs.
4. Habitation: This area focuses on habitation functions that closely interface with life-support systems, including food preparation and production, hygiene, metabolic waste collection, clothing/laundry, and the conversion of logistics trash to resources.
