Miniature Gas Sensor for Monitoring Biological Space Environments

The development of a versatile gas sensor for use in gravitational studies and/or long-term monitoring of biological systems in space must address a number of constraints beyond those found in Earth-based systems. Southwest Sciences proposes to combine a new type of laser with high sensitivity detection methods to develop a multiple gas sensor with application to biological measurements as well as health monitoring and fire safety in space environments. This sensor would provide excellent long-term stability, accuracy, reliability, and space worthiness. The results of Phase I shall provide the critical design information required to build a deliverable prototype multigas sensor in Phase II. The Phase II effort will lead to the commercialization of a rugged, compact multigas sensor for use by NASA in space applications as well as in the commercial sector.
