Abstract

As the duration of orbital missions and the size of the crews increase and as plans are made for exploration beyond Earth’s orbit, the ability to provide space crews with a healthy and comfortable living environment grows ever more complex. Advanced environmental control systems will be needed for both planetary exploration missions and permanent settlements beyond Earth’s atmosphere. New technologies will be needed to enhance water reclamation, produce O2, and remove carbon dioxide (CO2). The primary requirements for such a system will be minimal power usage and volume, robust autonomous operation, and a closed-loop design that minimizes reliance on stored consumables. Once we venture beyond low Earth orbit (LEO), the risks associated with radiation increase, the capability for frequent resupply diminishes, and medical assistance and evacuation become less available. Life support systems must become more “closed loop,” more robust, more efficient, more operationally simplified, more automated, and more reliable—while simultaneously requiring less energy-intensive, less massive, and less expensive technology.
