Air quality in the small, closed environment of a spacecraft cabin is always a critical matter for the safety, health, and comfort of the crew. The technologies used to keep air breathable in spacecraft have a unique set of requirements because of several constraints that become more important as the duration and distance of space missions lengthen. Technologies must be extremely robust, as supplies and spare parts are few and resupply may be impossible. They must be well coordinated and function in a tightly integrated life-support system. Mass, volume, and power consumption must be minimal due to the high cost of launch mass and limited solar/battery energy. This article examines some of the issues associated with spacecraft air revitalization and briefly reviews some of the technologies developed to maintain quality and minimize waste through recycling of air. We emphasize approaches for long-duration missions (i.e., more than one month), in which technologies need to be regenerable and the oxygen cycle needs to approach closure. We also discuss air revitalization systems for the International Space Station and needs for long-distance missions such as Mars transit.

This chapter highlights a successful grant proposal submitted in 2002 to the Division of Environmental Biology (DEB) located within the Directorate for Biological Sciences of the National Science Foundation (NSF) (Award NSF DEB-0217463). This NSF-funded grant proposal is an example of the use of spatial science outside of geography—in this case biology. Collectively, the research described below is known as spatial ecology.

This proposal is an example of a qualitative research design. Additionally, the proposal demonstrates that a thesis proposal is just that—a proposal. Whereas some thesis proposals may appear to be nearly completed works, this proposal is an example of a common—but effective—research proposal. The proposal identifies the key issues, methods, and study area and sketches the core theoretical framework that informs the study.
