This proposal targets complementary technology development to enhancement measurement systems that were targeted in the 2009 Venus Flagship Mission Study such as a GC-MS, nephelometers, or cameras/optical detectors. Significant development of the baseline instrumentation (GC/mass spectrometers) will be needed to meet the specifications for the 2021 mission. The proposed array of miniaturized, robust, high temperature (600-800 C) solid electrolyte chemical sensors can significantly augment decent phase data and provide useful instrumentation options during mission development. Similar sensors can be developed for other planetary studies with potentially harsh atmospheres. This class of sensors has been developed by MEI and OSU in cooperation with NASA and directed primarily towards engine exhaust measurements for enhanced flight measurement capabilities for future use in engine control and IVHM This technology has military and commercial applications as well, which fits well with NASA's mission for the promotion of advanced technology for civil aviation. This technology will also apply to in-situ measurement capabilities for coal power plants, industrial burners, boilers, gas turbines, and other engines.
