Low Mass/Power Sensor Suite for Spacesuits

To provide additional telemetry and data for long-term mission, the composition of internal atmosphere of spacesuits must be determined. Specifically, the unambiguous detection and quantification of carbon dioxide is crucial for mission completion. Detection of other gasses (ammonia, oxygen) is also necessary for a complete sensor suite. Seacoast Science and Case Western Reserve University propose a sensor suite for the sensitive and selective detection of CO2 and other specified gasses. This will be accomplished using Seacoast?s proprietary sensor and the application of specially polymers developed in the laboratory of Professor Rigoberto Advincula. We will develop a microsensor array for atmospheric gases, specifically CO2 and NH3 (Phase I) and integrate it into a compact mission-ready sensor suite. In Phase I the feasibility of developing the proposed system will be demonstrated. In Phase II a further optimized system will be fabricated, tested and delivered to NASA for validation.
